Ever since the announcement of the discovery of exoplanet Gliese 581g, there has been a buzz in the news, on websites, Twitter – pretty much everywhere
This is a space science nut's favorite story in years. A new planet found in the Goldylocks zone in a different solar system. Why not expect it?
It would not surprise me if in fact there is not one orbiting Gliese but that the nearest three dwarf stars did, just taking into account irony and error associated with the kind of assumptions that are made in this study.
Interesting fact of the day: when visiting the Keck telescopes in Hawaii, the astronomers hosting our group tell me that the infrared interferometry method they use to make these planet-finding observations are precise enough to detect a star's motion as small as one yard.
