I think the first thing to remember is: We are right at the beginning of this adventure. There's so much excitement that every little signal - every "wiggle" in a spectrum - gets people saying, "Oh! That might be life!" And then, on the other side, other people respond with, "I don't see enough wiggles, so there's probably not even an atmosphere. Dead planet. Move on." Both reactions are too fast.
Researchers have detected what they say is the strongest evidence yet of a coronal mass ejection (CME) coming from a star other than our Sun. CMEs are massive bursts of fast-moving plasma that can be detected thanks to the characteristic radio signal they produce. However, despite decades of searching, these signals have only been identified from the Sun. Now a team has identified a similar signal coming from a distant star in the Milky Way.
Astronomers found an atmosphere where they least expected itclinging to an exoplanet that's too small, too hot and too old to have air, at least in theory. James Webb Space Telescope (JWST) 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.
