Mars by Rosetta
On February 24, 2007, the ESA’s Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long way to a 2014 rendezvous with comet Churyumov-Gerasimenkoy, getting close enough to take some very detailed pictures. That data wasn’t initially released by the mission leader, but they were finally made available late last year, including this frame-filling photo of Mars that Rosetta took as it approached the planet, using its main science camera, OSIRIS.

OH MY STARS A Hubble Space Telescope image of an especially photogenic group of interacting galaxies called Arp 273. The larger of the spiral galaxies, known as UGC 1810, has a disk that is tidally distorted into a rose-like shape by the gravitational tidal pull of the companion galaxy below it, known as UGC 1813. Arp 273 lies in the constellation Andromeda and is roughly 300 million light-years away from Earth. (Photo: NASA via the Telegraph)

Sun through the ultraviolet filter. The colors represent different temperatures of gas, of which the red and blue the coldest and hottest green. The temperature on the surface of the Sun is about 6000 degrees Fahrenheit until the center reaches a staggering 15 million degrees.

October 3rd APOD: Io, the bright yellow Galilean moon of Jupiter. This is a true-color image taken by the Galileo spacecraft which orbited from 1995 to 2003. Sulfur and molten rock are the main ingredients for the strange surface color. Due to the strong gravitational force of Jupiter, Io’s interior is heated to extreme temperatures, causing molten rock to explode to the surface. With so many intense volcanoes, the surface is constantly being re-made. Some of the lava is so hot that it glows in the dark!

Aurora Over Norway
Credit & Copyright: Ole Christian SalomonsenExplanation: Auroras can make spectacular sights. Photographed above last weekend, flowing multi-colored auroras helped illuminate a busy sky above Tromsø, Norway. Besides the spectacular aurora pictured above, the photographer caught three satellites streaks, one airplane streak, and a friend trying to capture the same sight. Although auroras might first appear to be moonlit clouds, they only add light to the sky and do not block background stars from view. Called northern lights in the northern hemisphere, auroras are caused by collisions between charged particles from the magnetosphere and air molecules high in the Earth’s atmosphere. If viewed from space, auroras can be seen to glow in X-ray and ultraviolet light as well. Predictable auroras might occur a few days after a powerful magnetic event has been seen on the Sun.
