The Death of a Star: Type Ia Supernova Simulation

This animation shows a thermonuclear flame burning its way through a white dwarf star. The flame produces hot ash, which buoyantly rises as the flame burns. The ash breaks out of but remains gravitationally bound to the surface of the star and collides at a point on the opposite side of the star from the breakout location. The blue shows the approximate surface of the star and the orange shows the interface between the star and the hot ash produced by the flame.

NASA SDO - X1.1 Solar Flare, March 5, 2012

After several days of a quiet Sun, the solar activity is now high again. Big sunspot AR1429, which emerged on March 2nd, is crackling with strong flares. This morning brought the strongest so far--an X1-class eruption on March 5th at 0413 UT. This flare propelled a bright Coronal Mass Ejection into Space, which will probably miss Earth, but hit Mercury and Venus. Even if this CME misses, high-latitude sky watchers should still be alert for auroras in the nights ahead. An M2-class eruption from the same sunspot on March 4th produced another, wider CME that might yet intersect Earth. The cloud is expected to deliver a glancing blow to our planet's magnetic field on March 6th at 04:30 UT (+/- 7 hr). Take a look at the forecast from our friends at the NASA Goddard Space Weather Lab: http://iswa.gsfc.nasa.gov/downloads/20120305_085600_anim.tim-den.gif Credit: NASA SDO

Birth of the Tycho Brahe's 1572 supernova remnant

Animation showing the evolution of the supernova remnant over time until today's view. Artist's illustration of how a supernova remnant is born. The animation starts with the progenitor of Tycho Brahe's supernova of the year 1572. Following a titanic thermonuclear blast, which has blown apart a white dwarf star, material is ejected into interstellar space at an incredibly high velocity of up to 30,000 kilometres per second or one tenth of the speed of light! Over the last 4 centuries the debris have expanded to a diameter of more than 20 light years. Million degree hot gas as well as heated dust particles are seen in an composite image of the remnant today, which has been obtained with the Chandra and Spitzer Space Telescopes and the Calar Alto observatory. This real image concludes the animation. Credit and copyright: Max-Planck-Institut für Astronomie (Ors Hunor Detre, Oliver Krause) http://www.mpia.de/IRSPACE/Tycho_release
