What do we know about stars? How can stars teach us about ourselves, the Earth?
Is Earth safe from nearby exploding stars?
Scientists used an Earth system model to test how radiation from a nearby supernova would affect life on our planet. They found that the…
Dying stars create new elements
Astrophysicists showed that collapsing white dwarfs can eject enough material to form heavy elements.
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…

An astronomer analyzed ancient supermassive black holes with mathematical models and found they likely grew exponentially after light,…
Citizen scientists and AI help astronomers find galaxies
Scientists trained an AI algorithm to categorize distant galaxies using volunteer classifications. Their model could improve the accuracy of…
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…
Searching for the first supernovae in the universe
Astronomers developed new theoretical models for how stars evolve that suggest the JWST could glimpse the oldest stars in the universe…
Why the Milky Way is shaped like a spiral
A team of astronomers reconstructed a 3-part history of the Milky Way Galaxy by comparing the physics and chemistry of 10 million red giant…
