A planet is born Astronomers have for the first time imaged a planet so young — a mere 2 million years old — that it is still gathering material from its birth site, a disk of gas and dust surrounding a star 145 parsecs (473 light years) from Earth. It lies about as far from its star as Uranus does from our Sun. The finding was published on the arXiv preprint server on 17 October (A. L. Kraus and M. J. Ireland preprint at; 2011), although it had been shared at conferences previously. See for more.
