Each August, as planet Earth swings through dust trailing along the orbit of periodic comet Swift-Tuttle, skygazers enjoy the Perseid Meteor Shower. As Earth moves through the denser part of the comet’s wide dust trail this year’s shower peaks around 6:00 UT August 13, when light from a nearly full Moon masks all but the brighter meteor streaks.

The flow of hot gas toward a black hole has been clearly imaged for the first time in X-rays. The observations from NASA’s Chandra X-ray Observatory will help tackle two of the most fundamental problems in modern astrophysics: understanding how black holes grow and how matter behaves in their intense gravity.
This animation shows how a black hole may have formed in SN 1979C. The collapse of a massive star is shown, after it has exhausted its fuel. A flash of light from a shock breaking through the surface of the star is then shown, followed by a powerful supernova explosion. The view then zooms into the center of the explosion.
