Galaxies

The Hubble and Euclid space telescopes caught a stunning portrait of a dying star at the heart of the Cat's Eye Nebula.

The Milky Way nebula RCW 36 resembles a stunning cosmic bird of prey in an incredible Very Large Telescope image.

The galaxy NGC 941 was imaged by the Subaru Telescope at the summit of Maunakea, Hawai'i.

The JUICE spacecraft captured its first detailed glimpse of interstellar comet 3I/ATLAS, revealing a glowing coma and sweeping tail.

Astronomers have dived into the turbulent and chaotic heart of the Milky Way, discovering hidden chemistry around our galaxy's supermassive black hole.

Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.

It may be one of the most iconic sights in the night sky, but astronomers have never seen the Helix Nebula like this before.

"The knowledge of these will ultimately help us understand the formation of the first stars and planets and how our own Milky Way came into being."

Some newly found stars in a small galaxy called Sextans A are forming without some of the usual "ingredients," raising questions about how the early universe evolved.

There may not be as nearly as many small galaxies in the early universe as astronomers predict there should be, which has big implications for the story of how our universe grew up.
