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 […]

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, […]
