Astronomers have discovered that the birth of neutron stars with magnetic fields trillions of times stronger than Earth's magnetosphere is the "magic trick" behind superbright supernovas.

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown ...

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...

Astronomers have caught what may be a rare cosmic catastrophe unfolding 11,000 light-years away. A seemingly ordinary ...

In A Nutshell Scientists have identified 6,594 solar twins, stars nearly identical to our Sun, in the largest model-driven catalog of its kind ever assembled. Each star was assigned an estimated age, ...

Over 4 billion years ago, as planets were coalescing around the newborn Sun, our star may have gone on an epic road trip across the Milky Way along with thousands of stellar "twins." And we may owe ...

Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of physics.

Researchers at Nagoya University in Japan have conducted the most detailed simulation of the interior of stars and disproved a theory scientists have believed for 45 years: that stars switch their ...

Researchers have uncovered evidence for our sun joining a mass migration of similar "twins" leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created and studied an ...

When worlds collide…suns act squirrely. Astronomers have witnessed a rare and violent cosmic crash between two planets, and ...

An oddly-behaving star led two UW astronomers to capture rare evidence of a collision between two planets in a distant solar ...

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about 13.
