Martian 'ice cauldrons' are prime spot to hunt LGMs, say boffins

One of the reasons it's so hard to find life on Mars is that hardly anwyhere we've spotted on the red planet combines liquid water and survivable temperatures. Now a study from the University of Texas (UT) suggests such a place may exist, because it once had enough volcanic activity to produce the right conditions. The …

It has been an epic journey, much more than 12 years in the making, but Rosetta has gone out in a blaze of glory. The final commands were uploaded to the spacecraft mid-morning on September 29 – and now there is no going back. Rosetta was programmed to touch down on comet 67P some time in the late morning of September 30. It …
