But most stunning is the intense fireball meteor. … Read More →

The Tarantula Nebula is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud, about 180 thousand light-years away. The largest, most violent star forming region known in the whole Local Group of galaxies, the cosmic arachnid sprawls across this spectacular view composed with narrowband data centered on emission from ionized hydrogen and oxygen atoms. Within the Tarantula (NGC 2070), … Read More →

NGC 7789: Caroline’s Rose

Found among the rich starfields of the Milky Way, star cluster NGC 7789 lies about 8,000 light-years away toward the constellation Cassiopeia. A late 18th century deep sky discovery of astronomer Caroline Lucretia Herschel, the cluster is also known as Caroline’s Rose. Its flowery visual appearance in small telescopes is created by the cluster’s nestled complex of stars and voids. Now estimated to be 1.6 billion years young, the galactic … Read More →

Comet Machholz Approaches the Sun

Comet 96P/Machholz‘s original fame derives from its getting closer to the Sun than any other short period comet — half as close as Mercury — and doing so every five years. To better understand this unusual comet, NASA’s Sun-monitoring SOHO spacecraft tracked the comet during its latest approach to the Sun in October. The featured image composite shows the tail-enhanced comet … Read More →
