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 […]

Dying, nearby dwarf star is 12 time hotter than our sun

[CLICK ON IMAGE FOR HIGH RESOLUTION, Adam Block, Mt. Lemmon SkyCenter, Univ. Arizona] The gorgeous, gaseous shroud of a dying sun-like star, planetary nebula Abell 36 lies a mere 800 light-years away in the constellation of Virgo. Shrugging off its outer layers, the nebula’s central star is contracting and becoming hotter, evolving towards a final […]

Messier 91 galaxy, missing since 1781, was found by amateur astronomer in 1969

Messier 91 galaxy, missing  since 1781, was found by amateur astronomer in 1969

Barred spiral galaxy Messier 91 (M91) lies in the constellation of constellation of Coma Berenices. The galaxy’s bar stands out quite noticeably. The galaxy represents the faintest object in Charles Messier’s catalog, and he discovered it in 1781. Notably, a rare error by Messier caused the galaxy to go “missing” for centuries, until amateur astronomer […]

The center of our galaxy as viewed from Chile at dawn

[CLICK ON IMAGE FOR HIGH RESOLUTION, Babak Tafreshi (TWAN), ESO Ultra HD Expedition As dawn broke on March 27, the center of the Milky Way Galaxy stood almost directly above the European Southern Observatory’s Paranal Observatory. In the dry, clear sky of Chile’s Atacama desert, our galaxy’s dusty central bulge is flanked by Paranal’s four […]

A sunset on Mars: Slightly different

[CLICK ON IMAGE FOR HIGH RESOLUTION, Mars Exploration Rover Mission, Texas A&M, Cornell, JPL, NASA] What would it be like to see a sunset on Mars? To help find out, the robotic rover Spirit was deployed in 2005 to park and watch the Sun dip serenely below the distant lip of Gusev crater. … Fine […]

Saturn’s rings, edge on, as seen by Cassini

[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, ISS, JPL, ESA, NASA If this is Saturn, where are the rings? When Saturn’s “appendages” disappeared in 1612, Galileo did not understand why. Later that century, it became understood that Saturn’s unusual protrusions were rings and that when the Earth crosses the ring plane, the edge-on […]

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 […]
