Instead of a relatively distant dark galaxy, Westmeier thinks the object is more likely a regular gas cloud at the edge of the Milky Way ... data of the disk’s rotation are necessary to ...

The study is published in Astronomy & Astrophysics. Large spiral galaxies like the Milky Way are expected to take several billion years to form. During the first billion years of cosmic history ...

The image of Zhúlóng shows its spiral arms, an old central bulge and a large star-forming disc, which resembles the Milky Way. (Image Credit: © NASA/CSA/ESA, M ...

Large spiral galaxies like the Milky Way are expected to take several billion years to form. During the first billion years of cosmic history, galaxies are thought to be small, chaotic ...

Given its recognizable features and impressive size, the researchers have dubbed this galaxy the most distant Milky Way "twin" ever observed. The detection of such a fully formed spiral galaxy so ...

"What makes Zhúlóng stand out is just how much it resembles the Milky Way in shape, size, and stellar mass." Astronomers have discovered the most distant and thus earliest spiral galaxy ever ...

Astronomers are able to use magnetic fields to map our environment within the Milky Way using a technique called Faraday rotation. It works like this. There's a bunch of dust—literal dust grains ...

First, the gas in the central molecular zone (CMZ), a dense and chaotic region near the Milky Way’s core, appears to be ionised (meaning it is electrically charged because it has lost electrons ...

Among these was the Milky Way, the galaxy which is home to billions of stars including our own Sun and the planet we all live on. This is our galaxy, there may be many like it, but this one is ours.

(Xiao et al., arXiv, 2024) In addition, it's quite large for a galaxy in the early Universe, measuring some 62,000 light-years in diameter, with a mass comparable to that of the Milky Way. "What makes ...
