| First transiting planets in a star cluster discovered Posted: 26 Jun 2013 01:28 PM PDT All stars begin their lives in groups. Most stars are born in small groups that quickly fall apart. Others form in huge, dense swarms, where stars jostle with thousands of neighbors while strong radiation and harsh stellar winds scour interstellar space, stripping planet-forming materials from nearby stars. It would thus seem an unlikely place to find alien worlds. Yet 3,000 light-years from Earth, in the star cluster NGC 6811, astronomers have found two planets smaller than Neptune orbiting sun-like stars. |
