New technology expected to capture images of 20 billion galaxies in the next decade.

Astronomers witnessed two galaxies engaged in an intense deep-space battle for the first time. Watch the “cosmic joust” in action.

Galaxies come in many different variations, but astronomers classify them into four main types: spiral, elliptical, irregular and peculiar.

Euclid, a European space telescope, just captured 26 million galaxies to reveal the secrets of the dark universe.

Thus, astronomers of the P.K. Sternberg State Astronomical Institute (GAISH) MSU, thanks to X-ray data, discovered a fundamental X-ray difference between Seyfert type I and type II galaxies, as well ...

Looking at a distant galaxy means looking back in time.

Three Alma antennas on the 5km altitude plateau of Chajnantor in Chile. wikipedia, CC BY-SA Our study examined the distribution of dust in more than 100 distant galaxies, which we know were ...

Seyfert galaxies aren't as luminous and distant as quasars, making them a more convenient way to study similar phenomena in lower energy light, like infrared.

These galaxies – some hundreds of them and called the Little Red Dots – are very red and compact, and visible only during about 1 billion years of cosmic history.

“However, Seyfert galaxies are unique from other sorts of AGNs because the galaxy itself can still be clearly seen — different types of AGNs are so bright that it’s nearly impossible to observe the ...

Quasars were the first known member of the menagerie of active galaxies. But they all have one thing in common: a voracious appetite.

Rather than ripping up our fundamental models of the universe, the unexpectedly big and bright galaxies spied in the early universe by JWST probably have astrophysical explanations ...
