Astronomers have been surprised to see a huge shadow sweeping across a disk of dust and gas encircling a nearby star, and incredibly, it takes 16 years for just one rotation.
An international team of scientists, including researchers from the University of Chicago, has made the rare discovery of a planetary system with a host star similar to Earth's sun.
The constellation of Virgo is especially rich in galaxies, due in part to the presence of a massive and gravitationally-bound collection of over 1,300 galaxies called the Virgo Cluster.
