Zooming in on a nearby young star called HD 141569A, astronomers using the Subaru telescope on Mauna Kea, Hawaii, discovered a hole in a disk of gas and dust encircling the star. The existence of this large gap, which is about the size of the orbit of Saturn, supports the theory that this young star ended its infancy abruptly by ionizing and pushing away the gas in the disk from which it was born.
