Astronomers found an #atmosphere where they least expected it—clinging to an #exoplanet that’s too small, too hot and too old to have air, at least in theory.
Observations of the blazing-hot lava #planet TOI-561 b suggest not only that it has a thick atmosphere but also that it may have had one for billions of years.
This is the strongest evidence yet for "air" around a hot rocky world that isn’t just a temporary veil of #hydrogen and #helium left over from planetary formation.

The age of exoplanets began in 1992, when astronomers detected a pair of planets orbiting a pulsar. Now, NASA has announced that there are 6,000 confirmed exoplanets. Read more from @ScienceAlert:

Once again, don’t trust the output of any #AI assistant without verification. This is not the HR 8799 exoplanet system, it’s the YSES 1 exoplanet system.
