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

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 […]

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 […]

Alnitak, Alnilam, Mintaka: The glorious belt of Orion

[CLICK ON IMAGE FOR HIGH RESOLUTION /  Rogelio Bernal Andreo] Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie about 1,500 light-years away, born of Orion’s well-studied interstellar clouds. In fact, clouds of gas and dust adrift in this region have […]
