Hubble’s view of a few thousand of the Abell 1689 galaxy cluster

Hubble’s view of a few thousand of the Abell 1689 galaxy cluster

A new image from NASA’s Hubble Space Telescope shows an enormous collection of galaxies and star clusters in stunning detail. Hubble spied 10,000 or so of the estimated 160,000 globular star groupings thought to reside in the huge galaxy cluster Abell 1689, which lies about 2.25 billion light-years away from Earth. For comparison, our own […]

Andromeda on the rocks

[CLICK ON IMAGE FOR HIGH RESOLUTION]   The Andromeda Galaxy 2.5 million light years away is the most distant object easily seen by the unaided eye. Other apparent denizens of the night sky, stars, clusters, and nebulae, typically range from a few hundred to a few thousand light-years away and lie well within our own […]

Astrophotography winner: Two interacting galaxy groups

Astrophotography winner: Two interacting galaxy groups

[CLICK ON IMAGE FOR HIGH RESOLUTION]: Martin Pugh (Heaven’s Mirror Observatory) A careful look at this colorful cosmic snapshot reveals a surprising number of galaxies both near and far toward the constellation Ursa Major. The most striking is NGC 3718, the warped spiral galaxy near picture center. NGC 3718’s spiral arms look twisted and extended, […]

Sombrero Galaxy’s bulge packed with clusters of star clusters

Sombrero Galaxy’s bulge packed with clusters of star clusters

[CLICK ON IMAGE FOR HIGH RESOLUTION]  Caltech / Palomar Observatory / Paul Gardner, Salvatore Grasso, and Ryan Hannahoe Named the Sombrero Galaxy for its hat-like resemblance, M104 features a prominent dust lane and a bright halo of stars and globular clusters. Reasons for the Sombrero’s hat-like appearance include an unusually large and extended central bulge […]

Remarkable symmetry at center of 120,000 light-year-diameter Messier 109

Remarkable symmetry at center of 120,000 light-year-diameter Messier 109

[CLICK ON IMAGE FOR HIGH RESOLUTION]  / Bob Franke Beautiful barred spiral galaxy M109, 109th entry in Charles Messier’s famous catalog of bright Nebulae and Star Clusters, is found just below the Big Dipper’s bowl in the northern constellation Ursa Major. In telescopic views, its striking central bar gives the galaxy the appearance of the […]

[Click on image for high resolution.] Credit: Adam Block, Mt. Lemmon SkyCenter, University of Arizona Bright spiral galaxy NGC 3169 appears to be unraveling in this cosmic scene, played out some 70 million light-years away just below bright star Regulus toward the faint constellation Sextans. Its beautiful spiral arms are distorted into sweeping tidal tails […]

Neighbors: The relatively close Fornax galaxy cluster

Neighbors: The relatively close Fornax galaxy cluster

[CLICK ON IMAGE FOR HIGH RESOLUTION /  Marco Lorenzi] How do clusters of galaxies form and evolve? To help find out, astronomers continue to study the second closest cluster of galaxies to Earth: the Fornax cluster, named for the southern constellation toward which most of its galaxies can be found. Although almost 20 times more […]

Merry Yosemite Christmas!

Merry Yosemite Christmas!

[CLICK ON IMAGE FOR HIGH RESOLUTION / Wally Pacholka / AstroPics.com, TWAN A starry band of the Milky Way climbs over Yosemite Valley, Sierra Nevada Range, planet Earth. Jupiter is the brightest celestial beacon on the wintry scene, though. Standing nearly opposite the Sun in the constellation Taurus, the wandering planet joins yellowish Aldebaran and […]
