A halo of dark matter surrounding our Galaxy
Researchers studied the motions of stars in the outer regions of the Milky Way Galaxy and found that the gravitational field of a long,…

What lies between the stars?
Astronomers simulated the clouds of material between stars. They found that regions of space with more heavy elements tend to be cooler and…
JWST reveals properties of dusty star-forming galaxies
Astronomers used new JWST data to unravel the structures of 22 dusty star-forming galaxies that previous telescopes couldn’t see.
The fate of massive rotating stars
Researchers showed that massive stars at the end of their lives are more likely to collapse into black holes than to explode into…
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…
