An image of Antares, taken with the Very Large Telescope in interferometry mode. It is the most detailed picture of any star apart from the Sun. The star has 900 times the diameter of Sun and is (sort of) nearby at 550 light years distance, making it a great target for these observations. The star has an apparent diameter of 41 milliarcseconds, corresponding to the width of a human hair seen from 500 meters away.
