SPACE PHOTOS THIS WEEK: Giant Star, Mars Aurorae, More

November 25, 2008--A new image taken by the Hubble Space Telescope is the most detailed view yet of two massive star systems in the Carina Nebula, 7,500 light-years away.

The brightest, known as WR 25, is a binary star that sits at the center of the image. Its neighbor, Tr16-244, is a triple star system that lies to its upper left. Both systems contain supermassive stars that are quickly burning through their hydrogen fuel, emitting large amounts of light and heat.

The bright orange star that seems to sit to the left of WR 25 is actually a smaller object that's much closer to Earth.
