Astronomy and Space News. Mars Will Not Kill You. June 26, 2011. Artist’s impression of ‘Near Earth Asteroids.’ Credit: NASA/JPL. A newly discovered asteroid will pass menacingly close to Earth on Monday 27 June. The space rock, dubbed 2011 MD, will pass 12,000km above Earth’s surface over the southern Atlantic Ocean at about 11.30pm Australian Eastern Standard Time (AEST). For comparison, the distance between Earth and the moon is about 380,000 kilometres. Objects the size of a house, like this one, com...

http://russblib.blogspot.com/2015/08/august-stargazing.html

RussBLib - what the . Better late than never, in most things. Never pass up a chance to sit down or relieve yourself. Saturday, August 1, 2015. The truth is out there. Somewhere. Pushing Toward Earth 2.0. If you want to start hearing the StarDate program in your area, you can request a station to carry our program by emailing the request to. It may sound like a villain from a Marvel comic book, but a magnetar is really the "corpse" of a once-mighty star — and the most powerful magnet in the univers...

Astronomy and Space News - Astro Watch: New theory points to ‘zombie vortices’ as key step in star formation

http://www.astrowatch.net/2013/08/new-theory-points-to-zombie-vortices-as.html

Wednesday, August 21, 2013. New theory points to ‘zombie vortices’ as key step in star formation. But for the protostar to grow bigger, the spinning disk needs to lose some of its angular momentum so that the gas can slow down and spiral inward onto the protostar. Once the protostar gains enough mass, it can kick off nuclear fusion. 8220;After this last step, a star is born,” said Marcus, a professor in the Department of Mechanical Engineering. 8220;Current models show that because the gas in the disk is...

Astronomy and Space News - Astro Watch: Russian Proton-M Rocket Destroyed Over Siberia

http://www.astrowatch.net/2015/05/russian-proton-m-rocket-destroyed-over.html

Sunday, May 17, 2015. Russian Proton-M Rocket Destroyed Over Siberia. A Russian State Commission has begun the process of determining the reasons for the anomaly. ILS will release details when data becomes available. In parallel with the State Commission, ILS will form its own Failure Review Oversight Board (FROB). The FROB will review the commission’s final report and corrective action plan, in accord with U.S. and Russian government export control regulations. Some experts suppose that one of the cause...

Astronomy and Space News - Astro Watch: Magnetar Near Supermassive Black Hole Delivers Surprises

http://www.astrowatch.net/2015/05/magnetar-near-supermassive-black-hole.html

Friday, May 15, 2015. Magnetar Near Supermassive Black Hole Delivers Surprises. In 2013, astronomers announced they had discovered a magnetar exceptionally close to the supermassive black hole at the center of the Milky Way. Using a suite of space-borne telescopes including NASA's Chandra X-ray Observatory. Magnetars are dense, collapsed stars (called " neutron stars. That possess enormously powerful magnetic fields. At a distance that could be as small as 0.3 light years. The inset contains Chandra's cl...
