NASA’s Hubble finds that star formation in the Andromeda galaxy has undergone a 500-million-year decline.

This Hubble image features spiral galaxy NGC 4654, located 72 million light-years away in the constellation Virgo (the Maiden).

Media are invited to join NASA for a virtual news conference at 2 p.m. EDT, Wednesday, July 29, to preview the Nancy Grace Roman Space Telescope mission, scheduled to launch from the agency’s Kennedy Space Center in Florida on Sunday, Aug. 30. NASA will stream this event live through a variety of platforms. Learn where […]
Red, white, and blue stars glitter like a sparkler being waved on a dark night in this new image from NASA’s Hubble Space Telescope.
Blue and white stars shine brightly against crimson gas in this image from NASA’s Hubble Space Telescope.
More than 500,000 stars blaze red, white, and blue in this NASA Hubble image of the globular cluster Messier 3 (M3).

The subject of today’s NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more than 150 globular clusters in our galaxy, though there may be […]

Astronomers using NASA’s Hubble Space Telescope have found something they never expected — ultraviolet light from a galaxy that existed just 1.4 billion years after the big bang.

Some stars have planets. Others are orbited by brown dwarfs, balls of gas too massive to be planets, but too low-mass to be stars. Astronomers love these brown dwarf-star pairs because being paired with a star helps reveal a brown dwarf’s age. Ages of astronomical objects are often hard to measure, but essential for understanding […]
Looking somewhat like a swarm of bees returning to their hive, this NASA Hubble Space Telescope image features the galaxy cluster MACS0329-0211.
