Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of ...

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a ...

Hubble Space Telescope images have revealed a second massive collision between planetary bodies orbiting the nearby star Fomalhaut, roughly 25 light-years from Earth. The discovery, reported in a peer ...

Astronomers have uncovered evidence of a rare and violent collision between two planets orbiting a star known as Gaia20ehk, ...

A new study, published in The Astrophysical Journal, finally changes that. Using data from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), researchers built a three-dimensional map of ...

The Sun orbits in the thin disk of the Milky Way. It's located 27,000 light-years (8.3 kiloparsecs) from the Galactic Center, on the inner edge of the Orion spiral arm. It orbits around the galaxy ...

A groundbreaking study in galactic archaeology proves the Sun made a treacherous journey to reach its current home in the ...

"We found a collision within a collision. The galaxy collision triggered a wave of star formation that, over hundreds of millions of years, led to the birth and eventual collision of these neutron ...

Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising ...

Two powerful instruments of the NASA/ESA/CSA James Webb Space Telescope joined forces to create this scenic galaxy view. This ...

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 ...
