... Methane Discovered in the Atmosphere of Mars . ... 19.01.2009 . ... Credit: NASA Explanation: Why is there methane on Mars? ... An important confirmation that methane exists in the atmosphere of Mars occurred last week, bolstering previous controversial claims made as early as 2003 . The confirmation was made spectroscopically using large ground - based telescopes by finding precise colors absorbed on Mars that match those absorbed by methane on Earth. ...

Discover the cosmos! ... 2009 January 19 . Methane Discovered in the Atmosphere of Mars . Credit: NASA . ... The confirmation was made spectroscopically using large ground - based telescopes by finding precise colors absorbed on Mars that match those absorbed by methane on Earth. Given that methane is destroyed in the open martian air in a matter of years, the present existence of the fragile gas indicates that it is currently being released, somehow, from the surface of Mars. ...

... Be Stars . ... Stellar Winds . ... He had found the first emission line star. ... More emission line stars were found soon, and one had to make subclasses to keep some overview. Cas is a main sequence B-type star, and together with other such stars showing hydrogen emission it forms the class of "Be stars", where the "e" stands for emission. ... Struve further speculated that those stars would be surrounded by a disk, basically thrown off the stellar surface by the rapid rotation. ...

Estimating the NEO Population and Impact Risk: Past, Present and Future . ... Since most of the risk resides in the largest impactors, finding that fraction of the largest bodies, and that none of them has a significant chance of impacting in the next century or so, "retires" more than 90 % of the impact risk, including most of the risk of a globally catastrophic impact event. ... In the mid-size range, from ~150 m to ~1 km, the main risk is from tsunami generated by an ocean impact. ...
