Stellar flares could masquerade as life on exoplanets
Astronomers tested whether energy bursts from stars could artificially elevate typical “biosignature” gases on exoplanets.

The lifecycle of a steam world
Scientists studied exoplanets with high water contents and found that they initially have outer vapor layers, which then cool and shrink…
Machine learning helps find other Earths
Astronomers used an algorithm on stars with known exoplanets to identify 44 systems with potential Earth-like planets, 8 of which they…
What’s a Super-Earth made of?
Astronomers observed a super-Earth with properties requiring surface water or a steam atmosphere. It challenges the paradigm that rocky…
Astronomers find distant galaxies with neural networks
Researchers developed a computer algorithm that correctly predicted the light emission characteristics of ancient faraway galaxies based on…
How did Super Jupiters form?
Astronomers profiled the characteristics of exoplanet TOI-2145b to explore the origins of Super Jupiters. They suggested these massive…
Alien life could face threats from passing stars and supernovae
Astronomers examined 84 of the closest known stars with potentially habitable exoplanets and found that 3 face possible extinction-level…
Astronomers simulate hidden minor planets across the Galaxy
Researchers modeled how planets smaller than Earth formed and changed over the first billion years of their existence. They found these…
Exoplanets with weird orbits might be more habitable
Astronomers modeled the ideal climatic and atmospheric conditions for exoplanets and found that planets with non-circular orbits had more…
Astronomers discover new rare hot Neptunes
Scientists discovered 2 new examples of medium-sized, closely-orbiting exoplanets whose characteristics shed light on how planetary systems…
