The planet – named WASP-107b and found 200 light years away in the constellation Virgo – is a breakthrough that confirms many of scientists’ predictions about planets elsewhere in space. Scientists long expected it would be found on planets elsewhere in the universe, as it is in gas giants Saturn and Jupiter in our own neighbourhood. With time, it could help us see the atmosphere of planets far deeper into the universe than those we have studied before. “We hope to use this technique with the upcoming James Webb Space Telescope, for example, to learn what kind of planets have large envelopes of hydrogen and helium, and how long planets can hold on to their atmospheres,” said Jessica Spake, part of Exeter’s physics and astronomy department.

Planet with a 5,63,000-km-long tail discovered outside Solar System

India Today  

Astrophysicists have made a groundbreaking discovery regarding the exoplanet WASP-69 b, revealing that it possesses a comet-like tail of gas extending approximately 5,63,000 kilometers. This tail is formed as the planet, a hot Jupiter located 160 light-years from Earth, loses its atmosphere due to intense radiation from its host star. The observed tail is at least seven times longer than …

Astronomers Discover Extremely Rare, Jupiter-like Cloudless Exoplanet 575 Light Years Away from Earth

News 18  

It seems Jupiter has got competition as scientists discover an exoplanet 575 light years away from earth. A team of fifteen scientists led by Munazza Alam, an NSF Graduate Research Fellow, a National Geographic Young Explorer, and a third-year graduate student in the Department of Astronomy at Harvard University, used the Hubble Space Telescope to record data and observe the …

Astronomers find an exoplanet with a cloud-free atmosphere that's larger than Jupiter and has Saturn's mass

Firstpost  

The spectrum of WASP-96b shows the complete fingerprint of sodium, which can only be observed for an atmosphere free of clouds, Astronomers have found that a planet outside our solar system, which is similar to Saturn in mass and exceeds the size of Jupiter by 20 percent, has an atmosphere free of clouds. The spectrum of WASP-96b shows the complete …

Astronomers discover traces of helium in an exoplanet's atmosphere

Daily Mail  

Scientists have discovered helium in the atmosphere of an Exoplanet for the first time. The strength of the signal detected was so large that scientists believe the planet's upper atmosphere could extend tens of thousands of miles into space. This is the first time helium has been found on an exoplanet An international team of astronomers, led by a PhD …
