Astronomers have obtained the first image of a dusty disc closely encircling a massive baby star, providing direct evidence that massive stars form in the same way as their smaller brethren. This discovery, made thanks to a combination of ESO’s telescopes, is described in an article in this week’s issue of Nature.

In one aspect the life of the Mars500 crew is just like home: they have to clean the microwave, scrub the toilet, mop the floors and vacuum around. In this latest video diary Diego shows the crew hard at work keeping their home tidy - doesn't look so 'interplanetary'.

NASA’s Kennedy Space Center is helping with the unprecedented effort to save wildlife from the effects of the BP Deepwater Horizon oil spill in the Gulf of Mexico.

NASA officials will discuss an upcoming International Space Station spacewalk by two Russian cosmonauts during a news briefing at 2 p.m. CDT on Wednesday, July 21.

Tycho's Supernova, the red circle visible in the upper left part of the image, is SN 1572 is a remnant of a star explosion is named after the astronomer Tycho Brahe, although he was not the only person to observe and record the supernova. When the supernova first appeared in November 1572, it was as bright as Venus and could be seen in the daytime. Over the next two years, the supernova dimmed until it could no longer be seen with the naked eye. In the 1950s, the remnants of the supernova could be seen again with the help of telescopes. When the star exploded, it sent out a blast wave into the surrounding material, scooping up interstellar dust and gas as it went, like a snow plow. An expanding shock wave traveled into the surroundings and a reverse shock was driven back in toward the remnants of the star. Previous observations by NASA's Spitzer Space Telescope indicate that the nature of the light that WISE sees from the supernova remnant is emission from dust heated by the shock wave. To the right is a star-forming nebula of dust and gas, called S175. This cloud of material is about 3,500 light-years away and 35 light-years across. It is heated by radiation from the young, hot stars within it, and the dust within the cloud radiates infrared light. Image Credit: NASA/JPL-Caltech/UCLA
