Two studies of distant galaxy clusters point to different mechanisms of stopping the baby boom that reigned in the early universe.
Astronomers found six runaway stars when they applied a neural network to data from the European Space Agency’s Gaia mission, which is set to map a billion stars across the Milky Way and beyond.
At what point does a clump of gas ignite, turning into a star? Astronomers now have an answer to what makes a star — and what makes a brown dwarf.
A magnetic field appears to span the space between the Large and Small Magellanic Clouds, the two dwarf galaxies being consumed by our Milky Way Galaxy.
Astronomers have discovered an "iceball Earth" orbiting a star 13,000 light-years away. Multiple eyes on the sky have revealed some of this world's secrets.
