... Planets . ... The planets were found using the HARPS instrument on the 3.6m telescope at ESOтАЩs La Silla Observatory. ... A planet in orbit around a star causes the star to regularly move towards and away from observers on Earth. ... One newly discovered planet, HD 85512 b, is best hope found so far for a habitable exoplanet. ... The HARPS team so far have found that about 40% of stars similar to own Sun have at least one planet smaller than Saturn (which is 95 times more massive than Earth). ...

... These 'anomalies' include binary sources and lenses (especially a star with a planet), a finite extent of the source and its brightness profile, and rotation effects in the observer (earth around sun), the lens, and the source. To fit light curves which involve binary lenses, I have developed a code, which now works also for extended sources, and which also includes all rotation effects. ...

... solar system . ... Solar system ice: source of Earth's water . Scientific findings contradict prevailing theories about the relationship between comets and water-bearing carbonaceous chondrites and suggest that meteorites, and their parent asteroids, are the most likely sources of Earth's water. ... Therefore, by comparing the deuterium content of water in carbonaceous chondrites to the deuterium content of comets, it is possible to tell if they formed in similar reaches of the solar system. ...
