Hubble Captures a Suspected Galaxy Encounter

UGC 3912 is classified as a spiral galaxy … but you wouldn’t know it from this detailed NASA Hubble Space Telescope image. UGC 3912’s distorted shape is typically indicative of a gravitational encounter with another galaxy. When galaxies interact – either brush up against each other’s gravitational fields or even collide – their stars, dust, […]

Hubble Observes a Galactic Distortion

The galaxy NGC 5427 shines in this new NASA Hubble Space Telescope image. It’s part of the galaxy pair Arp 271, and its companion NGC 5426 is located below this galaxy and outside of this image’s frame. However, the effects of the pair’s gravitational attraction is visible in the galactic distortion and cosmic bridge of […]

Hubble Spies a Spinning Spiral

Looking like a baseball lobbed into the depths of the universe, ESO 420-G013 is a face-on spiral galaxy and a Seyfert galaxy. Dark lanes of dust are visible against the background glow of the galaxy’s many stars.  About 10 percent of all the galaxies in the universe are thought to be Seyfert galaxies. They are […]

Hubble Studies a Sparkling Galaxy Pair

A pair of small, interacting galaxies shine in this new NASA Hubble Space Telescope image. The larger of the two galaxies is named NGC 5410 and was discovered in 1787 by British astronomer William Herschel. It spans 80,000 light-years across and has a bright white bar of stars at its center. It is also a […]

Hubble Captures a Faint Bridge of Stars

One of the galaxies from a galactic group known as Arp 295 is visible in this new NASA Hubble Space Telescope image, along with part of the faint 250,000-light-year-long bridge of stars and gas that stretches between two of the galaxies. The galaxies have passed close enough together that their mutual gravity created this cosmic […]

How NASA Chases and Investigates Bright Cosmic Blips

Stephen Lesage’s phone started vibrating just after halftime on Oct. 9, 2022, while he was watching a soccer game in Atlanta with a friend. When Lesage saw the incoming messages, the match no longer seemed important. There had been a rare cosmic event, and he needed to get to his computer immediately. NASA’s Fermi Gamma-Ray […]

Hubble Glimpses a Bright Galaxy Group

This new NASA Hubble Space Telescope image shows a group of interacting galaxies known as LEDA 60847. LEDA 60847 is classified as an active galactic nuclei, or AGN. An AGN has a supermassive black hole in the galaxy’s central region that is accreting material. The AGN emits radiation across the entire electromagnetic spectrum and shines […]

New U.S. Postal Service Stamps Feature Iconic NASA Webb Images

The U.S. Postal Service has issued two new Priority Mail stamps celebrating NASA’s James Webb Space Telescope, the largest, most powerful, and most complex telescope ever put in space. The stamps, issued Jan. 22, feature images of the cosmos captured by Webb since it began its science mission in 2022. Webb is a mission led […]

Hubble Observes an Askew Galaxy Coaxing Star Formation from its Partner 

Arp 300 consists of two interacting galaxies, UGC 05028 (the smaller face-on spiral galaxy) and UGC 05029 (the larger face-on spiral). Likely due to its gravitational dance with its larger partner, UGC 05028 has an asymmetric, irregular structure, which is not as visible from ground-based telescopes but is quite distinct in this new image from […]

Hubble Views a Galactic Supernova Site

This image features a relatively small galaxy known as UGC 5189A, which is located about 150 million light-years away in the constellation Leo. This galaxy was observed by the NASA/ESA Hubble Space Telescope to study a supernova explosion in 2010 known as SN 2010jl.
