Hubble Views a Galaxy Under Pressure

NeRD

2 min read Hubble Views a Galaxy Under Pressure This NASA/ESA Hubble Space Telescope image shows dwarf galaxy, LEDA 42160. ESA/Hubble & NASA, M. Sun This NASA/ESA Hubble Space Telescope image shows LEDA 42160, a galaxy about 52 million light-years from Earth in the constellation Virgo. The dwarf galaxy is one of many forcing its way through the comparatively dense gas in the massive Virgo cluster of galaxies. The pressure exerted by this intergalactic gas, known as ram pressure, has dramatic effects on star formation in LEDA 42160. The gas…

Stellar Beads on a String

NeRD

Galaxy cluster SDSS J1531+3414 X-ray: NASA/CXC/SAO/O. Omoruyi et al.; Optical: NASA/ESA/STScI/G. Tremblay et al.; Radio: ASTRON/LOFAR; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded in the system known as SDSS J1531+3414 (SDSS J1531 for short). As explained in our press release, this mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling “beads on a string.” SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark…

Hubble Space Telescope tells a starry ‘tail’ of 12 mingling galaxies

NeRD

The Hubble Space Telescope has stepped on the tails of 12 interacting galaxies and found them to be studded with the shining diamonds of young star clusters  —scientists compare the phenomena to cosmic “strings of pearls.” When spiral galaxies interact, either through direct collision or close encounter, their spiral arms unravel. The gravitational force that a galaxy wields is vast, so when two galaxies become close, the gravitational tides that are raised tug on those spiral arms, pulling them out to form long “tails” that can stretch for many tens…

Hubble Spots a Galaxy Shrouded by Stars

NeRD

2 min read Hubble Spots a Galaxy Shrouded by Stars This Hubble image shows irregular galaxy, ESO 245-5, located some of 15 million light-years from Earth. ESA/Hubble & NASA, M. Messa This NASA/ESA Hubble Space Telescope image shows a densely packed field of stars laid upon a background of dust, gas, and light from more distant celestial objects. There are so many stars in this image’s field of view that it may be a little tricky to discern that you are in fact looking at a galaxy. Known as ESO…

NASA’s Hubble Traces ‘String of Pearls’ Star Clusters in Galaxy Collisions

NeRD

3 min read NASA’s Hubble Traces ‘String of Pearls’ Star Clusters in Galaxy Collisions Galaxy AM 1054-325 has been distorted into an S-shape from a normal pancake-like spiral shape by the gravitational pull of a neighboring galaxy, seen in this NASA Hubble Space Telescope image. A consequence of this is that newborn clusters of stars form along a stretched-out tidal tail for thousands of light-years, resembling a string of pearls. They form when knots of gas gravitationally collapse to create about 1 million newborn stars per cluster. NASA, ESA, STScI,…

Hubble Views a Dim but Distinct Galaxy

NeRD

2 min read Hubble Views a Dim but Distinct Galaxy Both visible and ultraviolet wavelengths of light comprise this Hubble Space Telescope image of the spiral galaxy UGC 11105. ESA/Hubble & NASA, R. J. Foley (UC Santa Cruz) This image of the softly luminous spiral galaxy UGC 11105 is from the NASA/ESA Hubble Space Telescope. It lies about 110 million light-years from Earth in the constellation Hercules. Astronomers have different ways of quantifying how bright celestial objects are. Apparent magnitude is one of those methods. It describes how bright an…

Hubble Observes a Galactic Distortion

NeRD

1 min read Hubble Observes a Galactic Distortion The galaxy NGC 5427 shines in this new NASA Hubble Space Telescope image. NASA, ESA, and R. Foley (University of California – Santa Cruz); Processing: Gladys Kober (NASA/Catholic University of America) 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…

Hubble Spies a Spinning Spiral

NeRD

2 min read Hubble Spies a Spinning Spiral This new NASA Hubble Space Telescope image features the face-on spiral and Seyfert galaxy, ESO 420-G013. NASA/ESA/A. Evans (University of Virginia)/Processing: Gladys Kober (NASA/Catholic University of America) 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…

NASA’s Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies

NeRD

6 Min Read NASA’s Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies Webb’s set of 19 PHANGS images of face-on spiral galaxies. Credits: NASA, ESA, CSA, STScI, Janice Lee (STScI), Thomas Williams (Oxford), and the PHANGS team It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes. Only NASA’s James Webb Space Telescope can deliver highly detailed scenes of nearby galaxies…

Bowen (Princeton University)/Processing: Gladys Kober (NASA/Catholic University of America) 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.…
