Using gravitational microlensing, scientists have discovered a rare, large planet at the edge of the Milky Way. The planet is ...

Astronomers have uncovered a colossal, searing-hot filament of gas linking four galaxy clusters in the Shapley Supercluster a ...

“For example, Chandra’s X-rays reveal the high-energy radiation around the supermassive black hole at the center of M31 as ...

"The fact that there is only around a 50-50 chance of a merger was very surprising." A titanic cosmic collision between the Milky Way and its closest large galactic neighbor, Andromeda, may not be as ...

The team found only a 2 percent probability that the galaxies will collide in the next five billion years. In slightly over half of the simulated scenarios, Andromeda and the Milky Way experience at ...

Scientists have built detailed Milky Way simulations under strange new physical laws to probe dark matter, revealing how ...

The Milky Way and the neighboring Andromeda galaxy are currently hurtling through space toward each other at a speed of about 250,000 miles per hour (400,000 kph), setting up a possible future ...

COZMIC simulator crafted detailed models of the Milky Way to investigate dark matter and how the universe might behave under ...

A vast filament of gas stretching across the cosmos may help solve the mystery of the Universe’s missing matter. Astronomers have identified a massive filament of hot gas connecting four galaxy ...

Created as a tribute to dark matter pioneer Vera Rubin, the image was created with the aid of a vast array of telescopes.

The knowledge that Andromeda is moving toward the Milky Way is core to our understanding of an expanding universe. Having four years previously figured out that Andromeda — a fuzzy blob to the ...
