Unlikely Planets Found In Violent Star Clusters 30
astroengine writes "When it comes to forming planets, Mother Nature isn't very picky. Despite horrific conditions inside densely packed open clusters, stars apparently have no problem forming and hanging on to an orbital brood. That's the conclusion from a new study (abstract) that used data collected by NASA's now-dormant Kepler space telescope to hunt for planets in a one-billion-year old open cluster called NGC 6811, a collection of about 70 stars located about 3,400 light years away in the constellation Cygnus."
Globular clusters (Score:5, Informative)
So far, the only place where planets haven’t been found yet is in globular clusters, an environment even more extreme that open clusters like NCG [sic!] 6811.
Aren't globular clusters very old? And, consequently, not very metallic? The lack of planets in them can hardly come as a surprise.
