A view of majestic Saturn, its rings and moon Rhea, courtesy of the Cassini spacecraft

[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SSI, JPL, ESA, NASA] Soft hues, partially lit orbs, a thin trace of the ring, and slight shadows highlight this understated view of the majestic surroundings of the giant planet Saturn. Looking nearly back toward the Sun, the robot Cassini spacecraft now orbiting Saturn captured crescent […]

Heaven above, North Korea below

[CLICK ON IMAGE FOR HIGH RESOLUTION / Jia Hao] Known in the north as a winter meteor shower, the 2014 Geminids rain down on this rugged, frozen landscape. The scene was recorded from the summit of Mt. Changbai along China’s northeastern border with North Korea as a composite of digital frames capturing bright meteors near […]

M1: The Crab Nebula — All that remains of an exploding star seen by astronomers in 1054

[CLICK ON IMAGE FOR HIGH RESOLUTION, Credit:Martin Pugh] The Crab Nebula is cataloged as M1, the first object on Charles Messier’s famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star, witnessed by astronomers […]

What caused the rare structure of the Polar Ring Galaxy NGC 660

[CLICK ON IMAGE FOR HIGH RESOLUTION, Gemini Observatory, AURA, Travis Rector (Univ. Alaska Anchorage)] NGC 660 is featured in this cosmic snapshot, a sharp composite of broad and narrow band filter image data from the Gemini North telescope on Mauna Kea. Over 20 million light-years away and swimming within the boundaries of the constellation Pisces, […]

CLICK ON IMAGE FOR HIGH RESOLUTION / ESA / Rosetta / MPS for OSIRIS Team; MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA/Elisabetta Bonora & Marco Faccin (Alive Universe Images) Spacecraft Rosetta continues to approach, circle, and map Comet Churyumov-Gerasimenko. Crossing the inner Solar System for ten years to reach the vicinity of the comet last month, the robotic spacecraft continues to […]

Stunning view of Saturn’s north pole

Stunning view of Saturn’s north pole

[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SSI, JPL, ESA, NASA] Acquiring its first sunlit views of far northern Saturn in late 2012, the Cassini spacecraft’s wide-angle camera recorded this stunning, false-color image of the ringed planet’s north pole. The composite of near-infrared image data results in red hues for low clouds and […]

Moon over Saturn

Moon over Saturn

[CLICK ON IMAGE FOR HIGH RESOLUTION, Carlos Di Nallo] What happened to half of Saturn? Nothing other than Earth’s Moon getting in the way. As pictured above on the far right, Saturn is partly eclipsed by a dark edge of a Moon itself only partly illuminated by the Sun. This year the orbits of the […]

The Hercules cluster offers clues about galaxy interactions

The Hercules cluster offers clues about galaxy interactions

[CLICK ON IMAGE FOR HIGH RESOLUTION, Image Credit & Copyright: Ken Crawford These are galaxies of the Hercules Cluster, an archipelago of island universes a mere 500 million light-years away. Also known as Abell 2151, this cluster is loaded with gas and dust rich, star-forming spiral galaxies but has relatively few elliptical galaxies, which lack […]
