Nearby M7 star cluster stands out in a sea of … stars, farther away at our galaxy’s center

[CLICK ON IMAGE FOR HIGH RESOLUTION, Lorand Fenyes] M7 is one of the most prominent open clusters of stars on the sky. The cluster, dominated by bright blue stars, can be seen with the naked eye in a dark sky in the tail of the constellation of the Scorpion (Scorpius). M7 contains about 100 stars […]

Hubble provides closeup of 100,000 stars in M15 near our galaxy’s center

[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble, NASA] Stars, like bees, swarm around the center of bright globular cluster M15. This ball of over 100,000 stars is a relic from the early years of our Galaxy, and continues to orbit the Milky Way’s center. M15, one of about 170 globular clusters remaining, is noted for […]

Dwarf galaxies: 200 million stars jammed 25 times closer together than in our Milky Way

[CLICK ON IMAGE FOR HIGH RESOLUTION] The bright core and outer reaches of giant elliptical galaxy M60 (NGC 4649) loom large at the upper left of this sharp close-up from the Hubble Space Telescope. Some 54 million light-years away and 120,000 light-years across, M60 is one of the largest galaxies in the nearby Virgo Cluster. […]

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 […]

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 […]

[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 […]

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 […]

Stardust memories

[CLICK ON IMAGE FOR HIGH RESOLUTION] Cosmic dust clouds sprawl across a rich field of stars in this sweeping telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Probably less than 500 light-years away and effectively blocking light from more distant, background stars in the Milky Way, the densest part of the […]
