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, […]

Lagoon Nebula: Baby stars on board

[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble Legacy Archive, NASA, ESA, Judy Schmidt] The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. The […]

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 […]

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 […]
