Magellanic gemstone in the southern sky [NGC 290]
Hubble has captured the most detailed image to date of the open star cluster NGC 290 in the Small Magellanic Cloud.
The image taken with the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope show a myriad of stars in crystal clear detail. The brilliant open star cluster, NGC 290, is located about 200,000 light-years away and is roughly 65 light-years across.

Electric Blue Lava Flows From Indonesia’s Deadly Kawah Ijen Volcano
There is a group of volcanoes in Indonesia that spew lava that burns with brilliant blue flames. Located in East Java, the Ijen volcano complex is a group of stratovolcanoes that are highly composed of sulfur, which when ignited produces a distinct blue-colored flame. At night when one of the active volcanoes of Ijen erupts, red lava flows run down the sulfuric slopes clothed in bright blue flames, resulting to an eerie, otherworldly spectacle. (via When On Earth)
"I think music is about our internal life. It’s part of the way people touch each other. That’s very precious to me. And astronomy is, in a sense, the very opposite thing. Instead of looking inwards, you are looking out, to things beyond our grasp."

This weekend marks the 45th anniversary of the first humans walking on the Moon, the Apollo 11 mission. Here’s one of the images from that mission in gif form; the famous Earthrise, as seen from the Command Module spacecraft that remained in Lunar Orbit while 2 astronauts descended to the surface.
Bismuth is a chemical element with an iridescent oxide surface.
Astronomers have long pondered the origins of enormous elliptical galaxies in the young Universe. An object 11 billion light-years away spotted by the Herschel mission may help unravel the mystery.
Two massive spiral galaxies merged to create a giant elliptical galaxy, which were previously believed to form through the absorption of dwarf galaxies over time.
