Galaxies in space the size of the Milky Way head for a collision

Galaxies in space the size of the Milky Way head for a collision

[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble Legacy Archive, NASA, ESA; Processing: Judy Schmidt] What will survive this battle of the galaxies? Known as Seyfert’s Sextet, this intriguing group …. actually contains only four interacting galaxies. Near the center of this Hubble Space Telescope picture, the small face-on spiral galaxy lies in the distant background […]

A view of Saturn that would have been impossible from Earth

A view of Saturn that would have been impossible from Earth

[CLICK ON IMAGE FOR HIGH RESOLUTION / NASA/JPL/SSI; Composition: Gordan Ugarkovic] This image of Saturn could not have been taken from Earth. No Earth based picture could possibly view the night side of Saturn and the corresponding shadow cast across Saturn’s rings. Since Earth is much closer to the Sun than Saturn, only the day […]

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

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 […]

Andromeda on the rocks

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 […]

NGC 2170: Celestial still life with a cosmic brush

[FOR HIGH RESOLUTION, CLICK ON IMAGE] / Adam Block, Mt. Lemmon SkyCenter, U. Arizona] The beautiful, dusty nebula NGC 2170 shines at the upper left. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a compact red emission region, and streamers of obscuring dust against a backdrop of […]
