This celestial object, known as NGC 5866 or the Spindle Galaxy, presents a fascinating sight when observed from its side. While many disk galaxies share similar thinness, NGC 5866's edge-on ...

Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe ...

An international team of astronomers has observed a high-redshift massive star-forming galaxy known as REBELS-25. They found that REBELS-25 is a dynamically cold disk galaxy. This finding was ...

Astronomers peering into some of the furthest reaches of our universe have made a “baffling” discovery: the most distant rotating disc galaxy ever observed. And it closely — if not eerily — resembles ...

Current models of massive galaxy formation suggest that they evolve as part of a slow growth process, gradually increasing in size through mergers with smaller galaxies and the accumulation of clumps ...

In a remarkable discovery, astronomers have found a disc around a young star in the Large Magellanic Cloud, a galaxy neighboring ours. It's the first time such a disc, identical to those forming ...

The Sombrero galaxy has long had a place in astronomical history as an intriguing object. The first written record of this galaxy was noted in 1781, almost 250 years ago, by Pierre Méchain, a French ...

Astronomers have spotted a massive disk galaxy, not unlike our own, that formed 12.5 billion years ago when our 13.8 billion-year-old universe was only a tenth of its current age. But according to ...

This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO ...
