An 18-member international team of researchers has found exciting new evidence that supports the theory of an extraterrestrial impact that occurred nearly 13 000 years ago. Their evidence lies in material found in a thin layer of sedimentary rock in Pennsylvania and South Carolina in the United States and in Syria.
Astronomers have used the NASA/ESA Hubble Space Telescope to study some of the smallest and faintest galaxies in our cosmic neighbourhood. These galaxies are fossils of the early Universe: they have barely changed for 13 billion years.
To better understand Saturn's moon Titan, scientists must study the methane in its atmosphere, the persistence of which was likely influenced by an ocean of water recently discovered 100 kilometers below the moon's surface.
The effect of spaceflight on a microscopic worm - Caenorhabditis elegans (C. elegans) - could help it to live longer. The discovery was made by an international group of scientists studying the loss of bone and muscle mass experienced by astronauts after extended flights in space.
A giant gas cloud is on collision course with the black hole in the centre of our galaxy in 2013. This is a unique opportunity to observe how a super massive black hole sucks in material, in real time.
