With the help of the NASA/ESA Hubble Space Telescope, a German-led group of astronomers have observed the intriguing characteristics of an unusual type of object in the asteroid belt between Mars and Jupiter: two asteroids orbiting each other and exhibiting comet-like features, including a bright coma and a long tail. This is the first known binary asteroid also classified as a comet. The research is presented in a paper published in the journal Nature this week.

A group-analysis of 30 exoplanets orbiting distant stars suggests that size, not mass, is a key factor in whether a planets atmosphere can be detected. The largest population-study of exoplanets to date successfully detected atmospheres around 16 hot Jupiters, and found that water vapour was present in every case. The work by a UCL-led team of European researchers has important implications for the comparison and classification of diverse exoplanets.

From blob-like jellyfish to rock-like lichens, our planet teems with such diversity of life that it is difficult to recognise some organisms as even being alive. That complexity hints at the challenge of searching for life as we dont know it the alien biology that might have taken hold on other planets, where conditions could be unlike anything weve seen before. The Universe is a really big place.

With NASA'sCassini spacecraftnow just a blur of molecules in Saturn's cloud tops, another gas giant is rotating into the crosshairs of the planetary exploration community. Cassini plunged intentionally to its death Friday(Sept. 15), bringing an end to 13 years of exploration that revolutionized researchers' understanding of the Saturn system and its ability to host life.

WASHINGTONAppearing silently and without warning in the space agencys parking garage, the Cassini probe reportedly emerged from the shadows Monday and uttered You thought you could get rid of me? while confronting petrified NASA administrator Robert Lightfoot, Jr. I bet you never thought youd see me again, did you? said the battered and scorched space craft, which reportedly came forth suddenly from behind a support column into the stark fluorescent light to confront the trembling NASA official. Your mistake wasnt trying to kill me, Robertit was not finishing me off when you had the chance.
