These gases could signify intelligent life beyond Earth
Astronomers proposed that the industrial gases nitrogen trifluoride and sulfur hexafluoride could provide measurable signs of advanced…
Scientists observe a changing exoplanet orbit
Astronomers conducted a multifaceted study of the exoplanet TrES-1 b and found that its orbit is shifting, possibly due to an unseen…
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…
