• Hubble witnesses death throes of ancient comet

  

  Astronomers have witnessed the beginning of the end of an ancient comet. After billions of years, Comet 332P may only have a century and a half left to live, as the Hubble Space Telescope captured detailed images of it fragmenting, throwing dozens of building-sized pieces into space. The observation is helping scientists learn about the life and death of comets. Named 332P/Ikeya-Murakami, astronomers believe the comet spent about 4.5 billion years in the Kuiper Belt, the rocky region beyond Nep..

• Should we be trying to colonise Venus instead of Mars?

  

  VIDEO Despite the fact that there's mounting evidence that Venus was once habitable, and was so similar to our own planet that it's been nicknamed 'Earth's twin next door', it doesn't really get talked about all that much. Certainly not as much as Mars. But Venus is millions of kilometres closer, so why aren't we interested in colonising it instead?  As this episode of Space Time explains, there's a huge disparity between the kind of attention that Mars and Venus get, both from space agencies a..

• Dino camouflage hints at forest home

  

  Recent research has found dinosaurs may have cooed instead of roared, and the infamous Tyrannosaurus Rex may have been even bigger than we imagine. Now, using a particularly well-preserved fossil with hints of skin pigmentation intact, researchers at the University of Bristol have managed to produce what they call "the most scientifically accurate life-size model of a dinosaur," and used it to infer the creature's likely habitat. An ancestor of Triceratops, the Psittacosaurus was a herbivore ab..
