Galaxies

"It has the potential to fully transform our view of the galaxy."

Seen by NASA's Chandra X-ray Observatory, this peaceful galaxy cluster existed when the universe was just 5.8 billion years old and brimming with chaos.

Astronomers have discovered a massive galaxy that does not seem to contain dark matter, a cosmic puzzle that could challenge theories surrounding the evolution of the universe.

Astrophotographer Miguel Claro captured an incredible panoramic image of the Milky Way from the Lut (Dasht-e Lut) desert in Iran.

The Extremely Large Telescope in Chile's Atacama Desert is halfway complete and already making astronomers excited for the view of the cosmos the telescope will provide.

Astronomers have now deduced what alien scientists might see when they gaze at the Milky Way from afar. Our home galaxy is unusual but not unique, at least when it comes to chemistry.

Astronomers have detected high-energy neutrinos coming from within our Milky Way galaxy, potentially opening up an exciting new window of research.

The Virgo Cluster and 1,900 galaxies shine in an incredible image captured from a dark sky preserve in Portugal, by photographer Miguel Claro.

NASA has produced sounds from telescope data on five galaxies in Stephan's Quintet, a binary star system called R Aquarii, and a giant galaxy known as Messier 104.

NASA's X-ray observatory detected the echo of a flare likely caused when an object, perhaps a gas cloud or star, was ripped apart by our galaxy's black hole.
