All in all, early galaxies seemed to be larger than what the standard model expected by "roughly a factor of two," study co-author Steve Finkelstein, an astrophysicist at the University of Texas ...

Astronomers may have uncovered the origins of the mysterious “little red dots,” some of the strangest galaxies seen in the ...

Using the James Webb Space Telescope (JWST), the team focused on several of these so-called tidal disruption events (TDEs) in dusty, shrouded galaxies. TDEs occur when a supermassive black hole at ...

However, not all spiral galaxies are created equal, as two recent images from the Hubble Space Telescope show. The image above shows galaxy NGC 3596, a neat and orderly spiral galaxy.

While the new James Webb Space Telescope has spotted even older galaxies, dating to within a mere 300 million years of the beginning of the universe, it’s the size and maturity of these six ...

Astronomers have discovered the most monstrous supermassive black hole ever. At 36 billion times more mass than our sun, it’s so big it’s pushing back the boundaries of possibility. They’ve even had ...

Those simulations also suggest what could become of the Triple if its galaxies do someday collide. "There would still be a galaxy, sort of this trainwreck initially," Satyapal said.

In roughly 4 billion years, our home Milky Way galaxy may collide with the neighboring Andromeda galaxy. We are approaching Andromeda at roughly 250,000 miles per hour, and scientists have ...
