Rare gas detected on distant exoplanet sheds light on planet formation: study

Sydney, June 2 (UNI) Astronomers have detected silicon monoxide gas in the atmosphere of a planet 850 lightyears from Earth, the first time the gas has ever been observed on any planet, including those in the solar system. According to a press release from the University of Newcastle in Australia on Monday, the research offers unprecedented insight into the formation and atmospheric chemistry of exoplanet WASP-121b, also known as Tylos. The planet, discovered in 2015, is an ultra-hot gas giant similar in size to Jupiter but far hotter, with temperatures exceeding 2,500 degrees Celsius, the release said. The international team, led by Tom Evans-Soma from the University of Newcastle and involved 18 institutions across Australia, Germany, the United States, Britain and India, used NASA's James Webb Space Telescope to observe Tylos continuously for 40 hours, which is the most comprehensive observation ever made of an exoplanet completing a full orbit, it said. Over 3,500 exposures, about one every minute, were captured, allowing researchers to analyze both the dayside and nightside atmospheres, said the study published in Nature Astronomy. While expected molecules like water vapor and carbon monoxide were found, the surprising detection of silicon monoxide and methane, rare on such hot planets, challenges existing atmospheric models, Evans-Soma said. The study suggests Tylos formed in a cold, distant region rich in ice and rocky material before migrating closer to its star, where intense heat vaporized the rocks into silicon monoxide, a planet born in ice and forged in fire, he said. Though Tylos is uninhabitable, the study advances the search for Earth-like planets by improving techniques to detect potential signs of life in distant atmospheres, he added. UNI XINDUA AKT SSP

3D map of exoplanet atmosphere shows wacky climate

Ammon News - Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics. According to a new paper published in the journal Nature, astronomers have mapped the 3D structure of the layered atmosphere of one such ultra-hot Jupiter-size exoplanet, revealing powerful winds that create intricate weather patterns across that atmosphere. A companion paper published in the journal Astronomy and Astrophysics reported on the unexpected identification of titanium in the exoplanet's atmosphere as well. As previously reported, thanks to the massive trove of exoplanets discovered by the Kepler mission, we now have a good idea of what kinds of planets are out there, where they orbit, and how common the different types are. What we lack is a good sense of what that implies in terms of the conditions on the planets themselves. Kepler can tell us how big a planet is, but it doesn't know what the planet is made of. And planets in the "habitable zone" around stars could be consistent with anything from a blazing hell to a frozen rock. Like the Transiting Exoplanet Survey Satellite (TESS), Kepler identifies planets using the transit method. This works for systems in which the planets orbit in a plane that takes them between their host star and Earth. As this occurs, the planet blocks a small fraction of the starlight that we see from Earth (or nearby orbits). If these dips in light occur with regularity, they're diagnostic of something orbiting the star. The frequency of the dips in the star's light tells us how long an orbit takes, which tells us how far the planet is from its host star. That, combined with the host star's brightness, tells us how much incoming light the planet receives, which will influence its temperature. (The range of distances at which temperatures are consistent with liquid water is called the habitable zone.) And we can use that, along with how much light is being blocked, to figure out how big the planet is. Last year, astronomers discovered an unusual Earth-size exoplanet they believe has a hemisphere of molten lava, with its other hemisphere tidally locked in perpetual darkness. And at about the same time, a different group discovered a rare small, cold exoplanet with a massive outer companion 100 times the mass of Jupiter. This latest research relied on observational data collected by the European South Observatory's (ESO) Very Large Telescope, specifically, a spectroscopic instrument called ESPRESSO that can process light collected from the four largest VLT telescope units into one signal. The target exoplanet, WASP-121b—aka Tylos—is located in the Puppis constellation about 900 light-years from Earth. One year on Tylos is equivalent to just 30 hours on Earth, thanks to the exoplanet's close proximity to its host star. Since one side is always facing the star, it is always scorching, while the exoplanet's other side is significantly colder.

Astronomers reveal 3D structure of an alien planet's atmosphere

By Will Dunham WASHINGTON (Reuters) - Astronomers for the first time have deciphered the three-dimensional structure of the atmosphere of a planet beyond our solar system, revealing three layers like a wedding cake on a ferociously hot gas planet that orbits close to a star bigger and hotter than our sun. The researchers peered through the atmosphere of WASP-121b, a planet also called Tylos, by combining all four telescope units of the European Southern Observatory's Chile-based Very Large Telescope, discerning a stratification of layers with different chemical compositions and intense winds. See for yourself — The Yodel is the go-to source for daily news, entertainment and feel-good stories. By signing up, you agree to our Terms and Privacy Policy. Until now, researchers have been able to determine the atmospheric chemical composition for some planets outside our solar system - called exoplanets - but without mapping the vertical structure or how the chemical elements were distributed. WASP-121b is an "ultra-hot Jupiter," a class of large gas planets that orbit close to their host star, making them extremely hot. Its atmosphere is mainly composed of hydrogen and helium, like that of Jupiter, our solar system's largest planet. But WASP-121b's atmosphere is not like anything ever seen before. The researchers differentiated three layers by looking for the presence of specific elements. WASP-121b's bottom layer was characterized by the presence of iron - a metal in gaseous form because of the incredible heat of the atmosphere. Winds move gas from the planet's eternal hot side to its cooler side. The middle layer was characterized by the presence of sodium, with a jet stream blowing circularly around the planet at about 43,500 miles (70,000 km) per hour - stronger than any winds in our solar system. The upper layer was characterized based on its hydrogen, with some of this layer being lost into space. "This structure has never been observed before and defies current predictions as to how atmospheres should behave," said astronomer Julia Victoria Seidel of the European Southern Observatory and the Lagrange Laboratory at the Observatoire de la Côte d'Azur in France, lead author of the study published this week in the journal Nature. The researchers also detected titanium in gaseous form in WASP-121b's atmosphere. On Earth, neither iron nor titanium exist in the atmosphere because they are solid metal owing to our planet's lower temperatures, relative to WASP-121b. Earth does have a sodium layer in the upper atmosphere. "For me, the most exciting part of this study is that it operates at the very limits of what is possible with current telescopes and instruments," said study co-author Bibiana Prinoth, a doctoral student in astronomy at Lund University in Sweden. WASP-121b has roughly the same mass as Jupiter but twice the diameter, making it puffier. It is located about 900 light-years from Earth in the direction of the constellation Puppis. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). WASP-121b is tidally locked, meaning that one side of it perpetually faces its star and the other side faces away, like the moon is to Earth. The side facing the star has a temperature around 4,900 degrees Fahrenheit (2,700 degrees Celsius/3,000 degrees Kelvin). The other side is at about 2,200 degrees Fahrenheit (1,250 degrees Celsius/1,500 degrees Kelvin). The planet orbits its star at about 2.5% of the distance of Earth to the sun. It is about a third closer to its star than our solar system's innermost planet Mercury is to the sun - so close that it completes an orbit in 1.3 days. Its host star, called WASP-121, is roughly 1-1/2 times the mass and diameter of the sun, and hotter. Being able to make out the structure of an exoplanet's atmosphere could be helpful as astronomers search for smaller rocky planets capable of harboring life. "In the future, we will likely be able to provide similar observations for smaller and cooler planets and thus more similar to Earth," Prinoth said, especially with the European Southern Observatory's Extremely Large Telescope due to be completed in Chile by the end of the decade as the world's largest optical telescope. "These detailed studies are necessary to provide context for our place in the universe," Seidel said. "Is Earth's climate unique? Can theories we derive from our one data point - Earth - actually explain the whole population of exoplanets?" "With our study we have shown that climates can behave vastly differently that predicted. There is much more diversity out there than what we have at home," Seidel added.
