To rule out false positives, astronomers must first understand a planet as well as they can about its geology and atmospheric processes. Ciencia y Ecología El telescopio James Webb revela nuevas claves sobre las "galaxias guisante" Estas peculiares galaxias fueron identificadas por primera vez en 2009 pero solo gracias al James . She lives near Boston. But Webb’s first capture of an exoplanet already hints at future possibilities for studying distant worlds. Webb sees the universe in infrared light, which is invisible to the human eye – and makes it the perfect space observatory to reveal details about distant worlds. Since HIP 65426 b is about 100 times farther from its host star than Earth is from the Sun, it is sufficiently distant from the star that Webb can easily separate the planet from the star in the image. Till vänster kan du se en bild av den är tagen av Nasa:s Spitzer Space Telescope's Infrared Array Camera. Liked this coffee mug ? That is because of the particulars of Webb’s optical system and how it translates light through the different optics. The James Webb Space Telescope will be able to see planets orbiting other stars and analyze gases and molecules on the surface. For the first time, astronomers have used NASA's James Webb Space Telescope to take a direct image of a planet outside our solar system. Webb observed the brighter elliptical galaxy (left) and spiral galaxy (right) in near-infrared light, and Hubble collected data in visible and ultraviolet light. Webb's landscape-like view, called "Cosmic Cliffs," is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. As HIP 65426 b is about 100 times farther from its host star compared to earth's distance from sun, it helped Webb to easily separate the planet from the star during observations. NIRISS was contributed by the Canadian Space Agency. 10:18 PM EDT, Thu September 1, 2022. The study of starlight that interacts with a planet’s surface or atmosphere will be carried out by astronomers. “It’s amazing to see the Webb performing so well.”. Astronomers have found more than 5,000 planets orbiting other stars (SN: 3/22/22). Your effort and contribution in providing this feedback is much The HIP 65426 b planet is more than 10,000 times fainter than its host star in the near-infrared, and a few thousand times fainter in the mid-infrared. The observation, which reveals the presence of specific gas molecules based on tiny decreases in the brightness of precise colors of light, is the most detailed of its kind to date, demonstrating Webb’s unprecedented ability to analyze atmospheres hundreds of light-years away. The James Webb Space Telescope revealed features of a new protostar forming. “Obtaining this image felt like digging for space treasure,” said Aarynn Carter, a postdoctoral researcher at the University of California, Santa Cruz, who led the analysis of the images. The discovery of thousands of planets orbiting other stars in our galaxy has provided new insights into the formation and evolution of planetary systems. She later took a career break to pursue further education and added a Master's in Science from the International Space University, France, to her Bachelor's in Journalism and Master's in Cultural Anthropology from Prague's Charles University. “This is a transformative moment, not only for Webb but also for astronomy generally,” said Sasha Hinkley, associate professor of physics and astronomy at the University of Exeter in the United Kingdom, who led these observations with a large international collaboration. September 2, 2022 at 11:02 am. Part of the allure of NGC 7469 — beyond its beautiful spiral shape — is that the galaxy is home to an active galactic nucleus (AGN). El Telescopio Espacial James Webb ha capturado su primera imagen directa de un exoplaneta. The exceptional detail and clarity of these measurements is possible because of Webb’s state-of-the-art design. From The Innovator's Workbench, featuring Casey McGlynn, Partner WSGR. Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) are both equipped with coronagraphs, which are sets of tiny masks that block out starlight, enabling Webb to take direct images of certain exoplanets like this one. It feels amazing.”. The finding of so-called barred galaxies, similar to our Milky Way . The small white star in each image marks the location of the host star HIP 65426, which has been subtracted using the coronagraphs and image processing. The telescope has already shared the first spectrum of an exoplanet by detecting a water signature in its atmosphere and found the first clear evidence of carbon dioxide in an exoplanet’s atmosphere. The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems I: High contrast imaging of the exoplanet HIP 65426 b from 2-16 μm. Jan 11, 2023, 03:10 am 2 min read.

The galaxies appear to dance with one another, showcasing how these interactions can drive galactic evolution. When the James Webb Space Telescope launches in December, astronomers around the world are expecting to find the unexpected, said Sara Seager, astrophysicist and planetary scientist at the . The ancients debated the existence of planets beyond our own; now we know of thousands. The exoplanet was first discovered in 2017 using the European Southern Observatory’s Very Large Telescope and its SPHERE instrument, located in Chile. El telescopio James Webb ha detectado signos inequívocos de dióxido de carbono en la atmósfera de un Júpiter caliente, un exoplaneta de características similares a Júpiter, pero que orbita mucho más cerca de su estrella. Promotional Offer - Get $200 cashback on any purchase of $500 or more with this offer. The James Webb Space Telescope captured the Cartwheel galaxy, which is around 500 million light-years away, in a photo released by NASA on August 2. Esta no es la primera imagen de este tipo, el telescopio Hubble ya. While the team has not yet studied the atmosphere of HIP 65426 b in detail, it did report the first spectrum — a measurement of light in a range of wavelengths — of an object orbiting a different star. Spitzer spent 1,000 hours staring at TRAPPIST-1 and was . Today, our mission remains the same: to empower people to evaluate the news and the world around them. The largest and most complex space telescope ever built, Webb is able to gather light that has been traveling for 13.5 billion years, almost since the beginning of the universe. Estas observaciones son un primer paso en la observación de CO2 y otros compuestos en la atmósfera de planetas similares a la Tierra. The image of an exoplanet would just be a spot, not a grand panorama, but by studying that spot, we can learn a great deal about it. How James Webb can help us find alien life. It then underwent an extraordinary sequence of deployment . Enter the Space & Beyond Box Photo Contest! Our mission is to provide accurate, engaging news of science to the public. July 21, 2022. This is because different elements and molecules absorb light at characteristic energies; and this is how we know where in a spectrum we might expect to see the signature of sodium (or methane or water) if it is present. The JWST will be able to fully characterize any new planet discovered… It is currently estimated that Planet 9 is quite large, but due to its size, most ground based telescopes would be unable to detect it. "The Spitzer Space Telescope played a gigantic role in uncovering the TRAPPIST-1 system and JWST is the follow-up," Nikole K. Lewis, an exoplanet scientist at Cornell University, told Space.com. They can then use this information to make inferences about the overall make-up of the planet, as well as how, when, and where it formed. That mission has never been more important than it is today. signal, Why fusion ignition is being hailed as a major breakthrough in fusion – a nuclear physicist explains, Jim Kaler, world-renowned expert on stars, dies at age 83, Distant suns provide the most precise test of electromagnetism yet, Astronomy Magazine Collection 2016-2020 DVD-ROM, James Webb helps shed light on black holes and star formation. A boiling Saturn-like planet 700 light-years away from the sun has become the best-explored planet outside our solar system. How is this good for studying exoplanets? Sin embargo, antes de que ese proyecto se concrete, la Nasa deberá pasar . WASP-96b, as the planet is known, is seven times as massive as Jupiter and circles a star nearly 400 light-years away. The James Webb Space Telescope's measurements of the planet's atmosphere have revealed unprecedented details of its chemistry, and even allowed astronomers to test methods for detecting alien life. We may even discover previously unknown planets, too.”. NASA said the Webb telescope will be able to glean new details about HIP 65426 b, including a more precise measurement of its mass and age. Lisa Grossman is the astronomy writer. NASA’s Nancy Grace Roman Space Telescope, slated to launch later this decade, will demonstrate an even more advanced coronagraph. WASP-96 b is one of more than 5,000 confirmed exoplanets in the Milky Way. Two galaxies, known as II ZW96, form a swirl shape while merging in the constellation Delphinus. Earth’s atmosphere absorbs a lot of the planet’s infrared wavelengths — exactly the wavelengths JWST excels at observing. “I think what’s most exciting is that we’ve only just begun,” Carter said. In addition, Webb’s extreme stability and its orbital location around Lagrange Point 2 roughly a million miles away from the contaminating effects of Earth’s atmosphere makes for an uninterrupted view and clean data that can be analyzed relatively quickly. Collaboration with ground-based telescopes can help us measure the mass of the planets, via the radial velocity technique (i.e., measuring the stellar wobble produced by the gravitational tug of a planet), and then Webb will do spectroscopy of the planet's atmosphere. Investigadores de la NASA afirman que un nuevo sistema de propulsión para grandes naves podría alcanzar Marte en una semana y Júpiter en solo un mes When a planet passes in front of a star, the starlight passes through the planet's atmosphere. Kristen Walbolt Photograph: Nasa/ESA/CSA, A Carter (UCSC), the ERS 1386 team, and A . As a result, the JWST will be able to see objects 13.6 billion years ago, approximately 100 to 250 million years after the Big Bang. The Hubble Space Telescope has snapped direct images of exoplanets before, but it remains tricky to accomplish from space because stars typically outshine planets. We earn a commission for every product bought through our website. The scientists are preparing a paper about the observations, but the findings have yet to be peer-reviewed. Spectroscopy is simply the science of measuring the intensity of light at different wavelengths. Hinkley led the observations of HIP 65426 b with an international team. The observations revealed that WASP-39b is shrouded in thick clouds containing sulfur and silicates. Light takes a long time to travel across the Universe, which means that the JWST can view the first stars and galaxies when they formed in the early universe. NIRISS is able to detect color differences of only about one thousandth of a micron (the difference between green and yellow is about 50 microns), and differences in the brightness between those colors of a few hundred parts per million. 1719 N Street, N.W., Washington, D.C. 20036, 4 key things to know about lung infections caused by fungi, 50 years ago, scientists sequenced a gene for the first time, Meet some of the microbes that give cheeses flavor, Complex supply chains may have appeared more than 3,000 years ago, Indigenous people may have created the Amazon’s ‘dark earth’ on purpose, Extreme weather in 2022 showed the global impact of climate change, No, Yellowstone isn’t about to erupt, even after more magma was found, We could get messages back from spacecraft sent through a wormhole, Io may have an underworld magma ocean or a hot metal heart, Humans haven’t set foot on the moon in 50 years.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages Webb for the agency and oversees work on the mission performed by the Space Telescope Science Institute, Northrop Grumman, and other mission partners. © The planet is about nine times Jupiter's mass. That is because of the particulars of Webb’s optical system and how it translates light through the different optics. Future US, Inc. Full 7th Floor, 130 West 42nd Street, Several important molecules, ices, and minerals have the ability to have strong chemical signatures in the visible and ultraviolet wavelengths when analyzed with Webb’s telescope. In any case, I urge the write to keep up the great work. Till . Its 270-square-foot gold-coated mirror collects infrared light efficiently. In spite of this, James Webb has shown . The exoplanet, or planet outside of our solar system, is a gas giant about six to 12 times the mass of Jupiter. A spectrum of light measured from another exoplanet, WASP-96 b, was one of the first Webb observations released to the public in July, but . Why is an infrared telescope key to characterizing the atmospheres of these exoplanets? A light curve from Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) shows the change in brightness of light from the WASP-96 star system over time as the planet transits the star. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Exoplanets are close to much brighter stars, so their light is generally overwhelmed by the light of the host stars. Nos interesa mucho tu opinión. To see a planet directly, astronomers have to block out the light from its star and let the planet’s own light shine, a tricky process. The observations are notable, however, because they hint at how the Webb telescope could be used to search for potentially habitable planets elsewhere in the universe. That’s probably out of JWST’s reach — Earth-sized planets are still too small see. “At first all I could see was light from the star, but with careful image processing I was able to remove that light and uncover the planet.”. Atmospheres are also essential for life as we know it: Having the right atmosphere allows for climate regulation, the maintenance of a water-friendly surface pressure, shielding from hazardous space weather, and the housing of life’s chemical building blocks. Esto ha sido parte del programa de, NASA & STScI | Disminución del brillo de WASP-39 durante el tránsito del exoplaneta, NASA & STScI | Variación de la luz absorbida en función de la longitud de onda. The planet, a gas giant . This part of the spectrum is particularly sensitive to water as well as other key molecules like oxygen, methane, and carbon dioxide, which are not immediately obvious in the WASP-96 b spectrum but which should be detectable in other exoplanets planned for observation by Webb. Both the Near-Infrared Camera and Mid-Infrared Instrument are also outfitted with so-called coronagraphs that help block out starlight. “There are many more images of exoplanets to come that will shape our overall understanding of their physics, chemistry, and formation. The image, as seen through four different light filters, shows how Webb’s powerful infrared gaze can easily capture worlds beyond our solar system, pointing the way to future observations that will reveal more information than ever before about exoplanets. The observations hint at how the Webb telescope could be used to search for potentially habitable planets elsewhere in the universe. An artist's depiction of the exoplanet WASP-39b. Webb will also carry coronagraphs to enable direct imaging of exoplanets near bright stars. Specifically, JWST is capable of measuring the chemical composition of exoplanet atmospheres with unprecedented sensitivity. That detection would rely on a similar atmospheric analysis as conducted on WASP-39b, then compare the results with models of alien planets. In each filter image, the planet appears as a slightly differently shaped blob of light. In addition, the much higher abundance of oxygen compared to carbon in the thick clouds revealed that WASP-39b formed much farther away from its star than it orbits today. One method Webb will use for studying exoplanets is the transit method, which means it will look for dimming of the light from a star as its planet passes between us and the star. In the habitable zone of its star, Proxima Centauri, Proxima b encounters bouts of extreme ultraviolet radiation hundreds of times greater than Earth does from the Sun. The study of exoplanets is providing clues to some of the most fundamental questions about our place in the Universe. Site Editor: “I’ve literally been waiting for this day for six years. We may even discover previously unknown planets, too.”. The combination of large size, short orbital period, puffy atmosphere, and lack of contaminating light from objects nearby in the sky makes WASP-96 b an ideal target for atmospheric observations. Galaxy II ZW 96, imaged here by the James Webb Space Telescope, is one of four merging luminous infrared galaxies (LIRGs) selected from the Great Observatories All-sky LIRGs Survey (GOALS) sample. The exoplanet in Webb’s image, called HIP 65426 b, is about six to 12 times the mass of Jupiter, and these observations could help narrow that down even further. The blue line on the graph is a best-fit model that takes into account the data, the known properties of WASP-96 b and its star (e.g., size, mass, temperature), and assumed characteristics of the atmosphere. This program aims to explore the complex, feedback-driven relationship between black hole growth and star formation. A transmission spectrum made from a single observation using Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) reveals atmospheric characteristics of the hot gas giant exoplanet WASP-96 b. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. At only four light-years away, Proxima Centauri b is our closest known exoplanet neighbor. While the light curve confirms properties of the planet that had already been determined from other observations – the existence, size, and orbit of the planet – the transmission spectrum reveals previously hidden details of the atmosphere: the unambiguous signature of water, indications of haze, and evidence of clouds that were thought not to exist based on prior observations. She worked as a reporter at the Engineering and Technology magazine, freelanced for a range of publications including Live Science, Space.com, Professional Engineering, Via Satellite and Space News and served as a maternity cover science editor at the European Space Agency. At only four light-years away, Proxima Centauri b is our closest known exoplanet neighbor. Exoplanets are close to much brighter stars, so their light is generally overwhelmed by the light of the host stars. The observatory's MIRI instrument. That object is called VHS 1256 b. It’s as heavy as 20 Jupiters, so it may be more like a transition object between a planet and a star, called a brown dwarf, than a giant planet. A NASA mission has spotted an Earth-size exoplanet orbiting a small star about 100 light-years away. Just because Proxima b’s orbit is in the habitable zone, which is the distance from its host star where liquid water could pool on a planet’s surface, doesn’t mean it’s habitable. Taking direct images of exoplanets is challenging because stars are so much brighter than planets. Subscribers, enter your e-mail address for full access to the Science News archives and digital editions. Located roughly 1,150 light-years away in the southern-sky constellation Phoenix, it represents a type of gas giant that has no direct analog in our solar system. From the ratios of carbon to oxygen, of potassium to oxygen, and of sulfur to hydrogen in the planet's atmosphere, the researchers inferred that the gas giant planet must have formed from collisions of several smaller planetesimals. Researchers will be able to use the spectrum to measure the amount of water vapor in the atmosphere, constrain the abundance of various elements like carbon and oxygen, and estimate the temperature of the atmosphere with depth. Visit our corporate site (opens in new tab). The system can detect biosignatures by studying planets as they pass in front of their host stars and capturing light that filters through their atmospheres. Mon, Mar 20, 2023 5:30pm PT. In effect, Webb is a time machine, allowing us to peer at the first galaxies to form after the Big Bang. On June 21, Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) measured light from the WASP-96 system for 6.4 hours as the planet moved across the star. The exoplanet, or planet outside of our solar system, is a gas giant about six to 12 times the . New images from NASA 's James Webb Space Telescope (JWST) reveal for the first time galaxies with stellar bars — elongated features of stars stretching from the centers of galaxies into their outer disks — at a time when the universe was a mere 25% of its present age. And the space observatory only began making scientific observations this summer. A second Earth-sized world is found in habitable zone of a star with three previously known planets. Discovery Company. Purple represents 3 micrometers, blue is 4.44 micrometers, yellow is 11.4 micrometers and red is 15.5 micrometers. The atmospheric composition of the hot gas giant exoplanet WASP-39 b has been revealed by the NASA/ESA/CSA James Webb Space Telescope. “We’ve demonstrated really how powerful JWST is as an instrument for the direct imaging of exoplanets,” says exoplanet astronomer and coauthor Aarynn Carter of the University of California, Santa Cruz. While the Hubble Space Telescope has analyzed numerous exoplanet atmospheres over the past two decades, capturing the first clear detection of water in 2013, Webb’s immediate and more detailed observation marks a giant leap forward in the quest to characterize potentially habitable planets beyond Earth. Webb also captured the spectral information of these galaxies (Photo credit: NASA) Three of the earliest galaxies have been identified from the deep-field image . That means the atmosphere is getting mixed up, with winds or currents pulling molecules from lower depths to its top and vice versa. The sheer intensity of starlight that batters WASP-39b makes the planet an ideal laboratory for studying such photochemical reactions, scientists said in the statement. Tereza is a London-based science and technology journalist, aspiring fiction writer and amateur gymnast. Explore the universe with news on fascinating discoveries, scientific advancements and more. The exoplanet HIP 65426 b in different bands of infrared light, as seen from the James Webb Space Telescope. The space telescope observed the planet on July 17 and July 30, capturing its glow in four different infrared wavelengths. A planetary tour through time. The new imaging reveals 66 star-forming regions within NGC 7469, nearly half of which went unseen in previous Hubble observations. Join our Space Forums to keep talking space on the latest missions, night sky and more! The shape of the planet doesn’t look like a perfect circle because of the telescope’s optics, in particular its hexagonal mirror. Estas observaciones son un primer paso en la observación de CO2 y otros compuestos en la atmósfera de planetas . “I think what’s most exciting is that we’ve only just begun,” Carter said.

Sign up for CNN’s Wonder Theory science newsletter. If the planet displays more oxygen than those models predict, for example, it could be a sign of life. “These are wavelengths of light that we’ve never ever seen exoplanets in before,” Hinkley says. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency. Researchers have been analyzing the data from these observations and are preparing a paper they will submit to journals for peer review. Nebulosa de Carina. peered through interstellar dust to see the galaxy's "bones. NASA's Webb telescope captures first evidence of carbon dioxide on an exoplanet. As carbon dioxide and nitrogen are released from terrestrial sources, methane is also released into the atmosphere by animals such as cows and volcanoes. “It was really impressive how well the Webb coronagraphs worked to suppress the light of the host star,” Hinkley said. With a mass less than half that of Jupiter and a diameter 1.2 times greater, WASP-96 b is much puffier than any planet orbiting our Sun. “There are many more images of exoplanets to come that will shape our overall understanding of their physics, chemistry, and formation. The exoplanet, or planet outside of our solar system, is a gas giant about six to 12 times the mass of Jupiter. In 2017, astronomers discovered HIP 65426 b and took a direct image of it using an instrument on the Very Large Telescope in Chile. The James Webb Space Telescope: A Revolutionary New Telescope. The observations even allowed astronomers to test methods that one day could help detect life on other exoplanets. The ring has a diameter of just 3,200 light-years, while the galaxy itself if some 90,000 light-years wide. The graphical representations of these measurements are called spectra, and they are the key to unlocking the composition of exoplanet atmospheres. An image shows the exoplanet HIP 65426 b in different bands of infrared light, as seen from the James Webb space telescope. These chemicals interact with the light of the parent star, producing sulfur dioxide in a reaction similar to the one that produces ozone in Earth's atmosphere. The dust of this star-forming region, rather than the stars themselves, is the highlight, and resembles ghostly figures. Visit the Shop to see more. Exoplanet Science™ is an Amazon Affiliate Program partner. Although NGC 7469 has been extensively studied in the past, JWST’s infrared vision lets researchers peer through the galaxy’s dense dust clouds like never before. The five galaxies of Stephan's Quintet can be seen here in a new light. We will be able to see Mars, the giant planets Venus, Jupiter, and Venus, as well as minor planets Pluto and Eris, and even small bodies in the solar system such as asteroids, comets, and Kuiper Belt Objects. Its discovery was announced in 2016. The two stars in WR140 produce shells of dust every eight years that look like rings, as captured by the Webb telescope. Manager: The exoplanet is about 100 times farther from its host star than Earth is from the sun, which allowed Webb and its instruments to separate the planet from its star. The instrument was designed and built by Honeywell in collaboration with the Université de Montréal and the National Research Council Canada. Updated This preliminary data indicates that the Webb instrument can detect faint chemical signatures in light from other planets, despite the fact that WASP-96b is unlikely to host life. According to an ESA release, these star-forming regions are largely concentrated in a “starburst ring” tightly wrapped around the galaxy’s core. January 09, 2023 9:51 PM. Webb's firsts keep coming: Observations of the exoplanet WASP-39 b show fingerprints of atoms and molecules, as well as signs of active chemistry and clouds. — James Webb Space Telescope will seek clouds of vaporized gems on exoplanets (Image credit: NASA, ESA, CSA, Joseph Olmsted (STScI)), James Webb Space Telescope will seek clouds of vaporized gems on exoplanets, James Webb Space Telescope spots alien planet shrouded in weird sand-filled clouds, Astronomers may be getting Webb Space Telescope exoplanet measurements wrong, Q&A with Dr. Z: Former NASA science chief talks about his 6 years at the helm. The exoplanet is a gas giant, meaning it has no rocky surface and could not support life. Astronomers have captured the first direct image of an exoplanet with the James Webb Space Telescope. We will gain a better understanding of the planet, its moon, and the other objects in our solar system by studying this. Discovered on 6 July 2017 by the SPHERE consortium, HIP 65426 b is a super Jupiter exoplanet orbiting the star HIP 65426. Astronomers have captured the first direct image of an exoplanet with the James Webb Space Telescope. The exoplanet is located about 355 light-years away from Earth and was first discovered in 2017, according to NASA. Scientists are analyzing Webb’s data of HIP 65426 b and a forthcoming study will be submitted to journals for peer review. The first images beamed back from NASA's James Webb Space Telescope (JWST) have stunned the world this year. B. This artist's concept portrays the seven rocky exoplanets within the TRAPPIST-1 system, located 40 light-years from Earth. Editor’s Note: This post highlights images from Webb science in progress, which has not yet been through the peer-review process. arXiv:2208.14990. Webb’s view, at longer infrared wavelengths, reveals new details that ground-based telescopes would not be able to detect because of the intrinsic infrared glow of Earth’s atmosphere. These are extremely bright regions at the hearts of some galaxies that shine due to the light emitted from superheated gas and dust as it violently swirls around a central supermassive black hole. It’s been done before, but for only about 20 planets total (SN: 11/13/08; SN: 3/14/13; SN: 7/22/20). Astronomers used NASA's planet-hunting TESS mission to spot the fourth world in . Follow us on Twitter @Spacedotcom and on Facebook. One of the main uses of the James Webb Space Telescope will be to study the atmospheres of exoplanets, to search for the building blocks of life elsewhere in the universe. NASA, ESA, CSA, e STScI. All Rights Reserved. The gas giant is up to 12 times the mass of Jupiter and its orbit is around 100 times farther from its host star than Earth is from the sun. Though the poster could have been a little more diplomatic, the comment does raise a valid point. “What we’d like to do is get down to study Earths, wouldn’t we? WASP-39b is a gas giant about one-third the size of the solar system's largest planet, Jupiter, and orbits only 4.3 million miles (7 million kilometers) away from its parent star, or eight times closer than the distance of the solar system's innermost planet Mercury from the sun.
