How did Mars get its moons?
Astronomers calculated possible trajectories for small objects approaching Mars. They found that as many as 1 in 50 get captured in orbit,…

Astronomers model early star clusters
Scientists used computer simulations to determine how ancient star clusters formed. Their results were similar to real clusters found with…
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…
Where do deep-space gamma-rays come from?
Researchers found that distant star-forming galaxies can only account for about half of the high-energy radiation from outside the Milky Way…
The Sun’s coldest regions are warmer than expected
Researchers found that the coldest regions of the Sun’s surface are much hotter than models predicted, likely due to turbulence in its…
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…
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…
The universe’s dust is on the decline
Astronomers found the density of dust in the universe has been steadily decreasing for the last 10 billion years, as it coalesced to form…
Creating a cosmic family tree
Astronomers traced the genealogy of a kilonova explosion by using models to find its most likely parent stars.
