A new analysis of Hubble surveys, combined with simulations of galaxy interactions, reveals that the merger rate of galaxies over the last 8 billion to 9 billion years falls between the previous ...
New simulations suggest dark matter could explain the mysterious gamma-ray glow at the Milky Way’s center. The findings show that the galaxy’s early mergers may have shaped dark matter in a way that ...
For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287.

A gamma ray glow at our galaxy’s center has puzzled scientists for almost two decades. New computer simulations back the ...
Scientists at Johns Hopkins may be closing in on dark matter’s elusive trail, uncovering a mysterious gamma ray glow at the ...
In recent groundbreaking research published in Monthly Notices of the Royal Astronomical Society, scientists from the University of Queensland have provided insights into the likely fate of our galaxy ...
An artist's concept depicts the Milky Way galaxy and its spiral shape. Our solar system is located in one of the spiral arms. - NASA/JPL-Caltech A collision between our Milky Way galaxy and its ...
The chance that our Milky Way Galaxy will collide with the Andromeda Galaxy may not be as certain as previously thought, according to researchers, who say that a new simulation has found a 50% chance ...
A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope. The interacting galaxy ...
