New Moon brings excellent dark-sky conditions for observing galaxies, nebulae, and star clusters in the sky this week.

JWST has detected the earliest galaxies in the universe, but some look “more mature” than expected. Is it time to rethink how ...

Dozens of 'wandering' black holes could be tumbling through our galaxy right now, new simulations hint. Their existence could ...

Astronomers have observed a massive and extremely active barred spiral galaxy in the early Universe and found that it has important similarities and differences with modern galaxies. This improves our ...

The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it's sensed light from a ...

Astronomers have observed two distant galaxies - both possessing roughly as many stars as our Milky Way - careening toward ...

Astronomers caught a brutal act of cosmic violence for the first time—one galaxy piercing another with deadly radiation.

As one galaxy smashed into the other, the winner pieced its cosmic victim, leaving behind a high level of radiation in a ...

The quasar’s radiation is stripping away gas in its companion galaxy, leaving behind clumps too compact to form new stars.

From a dark site, an 11-inch telescope will reveal several hundred galaxies here, so take your time and be sure of your ...

Astronomers are using Hubble to study vivid gas clouds and newborn stars in the tilted spiral galaxy NGC 3511.

A new, more detailed study of 1,000 distant galaxies explains why some gas-rich galaxies don’t produce as many stars as you’d ...
