Methane, on the other hand, although found in abundance on Jupiter, Saturn, Uranus, and Neptune, was tricky to spot on exoplanets located so far away, at least by means of space-based spectroscopy.

NASA’s Juno spacecraft has once again delivered a stunning view of Jupiter’s ever-changing atmosphere. In this latest image, a trail of drifting clouds ...

Jupiter's atmosphere is mostly composed of hydrogen and helium, with small amounts of ammonia, methane, water vapor and other gases. These latter components condense at different levels to form ...

For the first time ever, the James Webb telescope has detected methane in an exoplanet's atmosphere. Wed, 19 Feb 2025 13:36:55 GMT (1739972215991) Story Infinite Scroll ...

Now, James Webb has detected methane in an exoplanet’s atmosphere for the first time. The exoplanet in question is WASP-80 b, which is what astronomers call a “warm Jupiter.” ...

Astronomers have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an ...

Cassini’s cameras come equipped with filters that sample three wavelengths where methane gas absorbs light. These are in the red at 619 nanometer (nm) wavelength and in the near-infrared at 727 ...

Scientists still don’t know what gives it its characteristic hue; its atmosphere is primarily hydrogen, helium and methane. How common is this event Jupiter reaches opposition every 13 months or so.

Hill used the absorption bands of methane (619 nm) and ammonia (647 nm), both well-known features in Jupiter's visible spectrum, to calculate the abundance of these gases above Jupiter’s cloud tops.
