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.

Music by Zero Project. The hunt for planets beyond our solar system has reached a fever pitch. With some 500 planets revealed by ground telescopes, now, the ultimate planet finder, the Kepler space telescope, has released a tsunami of data. Among over a thousand new planet prospects are 200 multi-planet solar systems and 58 worlds in life-friendly orbits. They're all within a narrow window on the sky the size of your hand. That's why this may be the tip of the iceberg in a galaxy that's literally crawling with planets. Scientists are now beginning to envision what these worlds are like, with atmospheres, oceans, geological history. In the process, they are redefining what a planet might need to spawn life.

Hubblecast 22: Hubble Space Telescope Directly Observes Exoplanet Orbiting Fomalhaut.
The NASA/ESA Hubble Space Telescope has discovered an extrasolar planet, for the first time using direct visible-light imaging. The strange world is far-flung from its parent star, is surrounded by a colossal belt of gas and dust, and may even have rings more impressive than Saturn's.

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.
