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.
NASA will host an audio-only media teleconference at 11 a.m. EDT, Wednesday, June 17, to preview the Katalyst Space mission to boost the orbit of NASA’s Neil Gehrels Swift Observatory. Katalyst’s robotic servicing spacecraft, called LINK, will attempt to rendezvous with Swift and raise its altitude, extending its science mission lifespan and advancing a key […]
Help identify star-forming clumps in galaxy images, and help train machines to do the same.
The Payload for Ultrahigh Energy Observations (PUEO) is a NASA Astrophysics Pioneers Program mission designed to detect the most energetic particles in the universe.
Look closely at this image from NASA’s Hubble Space Telescope and you’ll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the […]
This NASA Hubble Space Telescope image reveals an enigmatic galaxy with a bright center and a face that hints at spiral structure, yet it holds no obvious spiral arms. Reddish-brown clumps and filaments of dust partially obscure the galaxy’s full face, while red, blue, and orange light from distant galaxies shines through its diffuse outer […]
