That’s no asteroid! – On the evening of 21 February 1906, A. Kopff discovered asteroid 596 Scheila. It was found to have a fairly typical Main Body orbit, meaning that it lives comfortably in the middle of the Asteroid Belt between Mars and Jupiter. Beyond that, it never attracted much notice, being just one amongst billions of asteroids. –Urban Astronomer

Incredible Engineering Camera Views of the Space Shuttle in Action – Whenever there is any issue with the space shuttle, you’ll hear talk about the engineering camera footage that NASA can look at to review with a fine-tooth comb everything that took place during launch and ascent. Here is a look at some of that footage — in high resolution, and in super slow-motion — to provide a glimpse of the intricate details engineers look for. –Nancy Atkinson / Universe Today

Geminids – First Session Results – was able to spend ~40 minutes watching the Geminids so far tonight. This first session lasted from 11:43 pm (6:43 UT) till 12:28 am (7:28 UT). With a limiting magnitude of +5.4, I counted 23 meteors with 13 being Geminids and 10 being non-Geminids –Carl Hergenrother

Saturn Rings Formed From Moon Gone – Saturn’s rings are one of the most awe-inspiring features in the solar system but they may have had a violent creation 4.5 billion years ago according to a new theory advanced by astronomer Robin M. Canup at the Southwest Research Institute in Boulder, Colorado, published in Nature. –Spaceports

Epic Filament Eruption - A very long solar filament that had been snaking around the Sun erupted (Dec. 6, 2010) with a flourish. STEREO (Behind) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km long (about half a solar radius) and a prominent feature on the Sun visible over two weeks earlier before it rotated out of view. Filaments, elongated clouds of cooler gases suspended above the Sun by magnetic forces, are rather unstable and often break away from the Sun. - Courtesy of SOHO/STEREO consortium. SOHO is a project of international cooperation between ESA and NASA.

A Dazzling Planetary Nebula

This picture of NGC 6572 shows the intricate shapes that can develop as stars exhale their last breaths. Hubble has even imaged the central white dwarf star, the origin of the dazzling nebula, but now a faint, but hot, vestige of its former glory. - Credit: ESA/Hubble & NASA
