JWST confirms giant planet atmospheres vary widely
Mar 28, 2023 (SPX)
Using NASA's James Webb Space Telescope (JWST), the researchers discovered that the atmosphere of exoplanet HD149026b, a 'hot Jupiter' orbiting a star comparabl...
Planet hunting and the origins of life
Mar 28, 2023 (SPX)
Degrees in pocket, Ricker returned to MKI as a research scientist. Then, as now, much of his research was devoted to developing solid-state photon detectors bas...
Webb measures temperature of rocky exoplanet for first time
Mar 27, 2023 (AFP)
When the Trappist-1 system was discovered in 2017, astronomers were excited at the prospect that some of its seven rocky planets -- which are roughly similar to...
Small stars may host bigger planets than previously thought
Mar 27, 2023 (SPX)
Gas giants, like other planets, form from disks of material surrounding young stars. According to core accretion theory, they first form a core of rock, ice and...
Webb Telescope spots swirling, gritty clouds on remote planet in spectrum data
Mar 23, 2023 (SPX)
Cataloged as VHS 1256 b, the planet is about 40 light-years away and orbits not one, but two stars over a 10,000-year period. "VHS 1256 b is about four times fa...
Searching for life with space dust
Mar 23, 2023 (SPX)
When you hear the words vacuum and dust in a sentence, you may groan at the thought of having to do the housework. But in astronomy, these words have different ...
Researchers detect silicate clouds, methane, water, carbon monoxide on distant planet
Mar 23, 2023 (UPI)
