Astronomers studying a distant galaxy cluster stumbled upon ancient radio signals that might hold clues to the formation of the early universe. While studying the distant galaxy cluster known as ...

This intermediate spiral galaxy spans roughly 65,000 light-years—about half our own galaxy’s width, yet every bit as dynamic. At its core lurks a supermassive black hole weighing between 3 and 10 ...

Astronomers have long sorted galaxies into types based on their visible structure. Spiral galaxies, like our Milky Way, have a flat disk, winding spiral arms and ongoing star formation. Ellipticals ...

An old galaxy reveals clusters of young stars that have formed in an unusually synchronized fashion, challenging the idea ...

An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by models ...

A maelstrom of star formation close to the center of our galaxy has been revealed in two different wavelengths by the James ...

A nearby galaxy is ablaze with new stars in a dazzling new image from the James Webb Space Telescope. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

Researchers have found that there’s something highly unusual about the Milky Way that sets it apart from galaxies which, on a surface level, appear similar. The distinction is technical but ...

Sci-fi tends to paint the edge of our galaxy as a desolate backwater, but in one early galaxy, the galactic rim is the bright, bustling center of activity, and the core is the aging backwater. The ...

Cosmologists may have to rethink galaxy evolution theories as more mature and orderly galaxies are found in the early universe. Credit: NASA / ESA / CSA / Joseph Olmsted (STScI) illustration Imagine ...

A potential dark galaxy — one made primarily of dark matter — may have been spotted in the local universe. Dark galaxies are theoretical, starless systems whose discovery could help astronomers better ...
