Default Poof! Planet-Forming Disk Vanishes Into Thin Air

Some 460 light-years away in the constellation Centaurus, a thick disk of dust swirled around a young star named TYC 8241 2652 1, where rocky planets like our own were arising. Then, in less than 2 years, the disk just vanished. That's the unprecedented observation astronomers report in a new study, out today. Even more intriguing: The same thing may have happened in our own solar system.
