Hubble Monitors Supernova In Nearby Galaxy -- This is a Hubble Space Telescope (HST) composite image of a supernova explosion designated SN 2014J in the galaxy M82. At a distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades. The explosion is categorized as a Type Ia supernova, which is theorized to be triggered in binary systems consisting of a white dwarf and another star - which could be a second white dwarf, a star like our sun, or a giant star. Astronomers using a ground-based telescope discovered the explosion on January 21, 2014. This Hubble photograph was taken on January 31, as the supernova approached its peak brightness. The Hubble data are expected to help astronomers refine distance measurements to Type Ia supernovae. In addition, the observations could yield insights into what kind of stars were involved in the explosion. Hubble's ultraviolet-light sensitivity will allow astronomers to probe the environment around the site of the supernova explosion and in the interstellar medium of the host galaxy. Because of their consistent peak brightness, Type Ia supernovae are among the best tools to measure distances in the universe. They were fundamental to the 1998 discovery of the mysterious acceleration of the expanding universe. A hypothesized repulsive force, called dark energy, is thought to cause the acceleration.

The moon's Hayn Crater, located just northeast of Mare Humboldtianum, is an exquisite example of a complex crater. The central peak complex in the image above is dramatically illuminated by the low Sun casting long shadows across the crater floor. The floor of Hayn crater contains spectacular remnants of the impact event: impact melt, slump blocks, and complex debris. In some areas, rocks on the floor have cracked and eroded into fields of boulders. Credit: NASA/GSFC/Arizona State University #nasagoddard #moon #crater #space #science

Hubble Looks in on a Nursery for Unruly Young Stars This striking new image, captured by the NASA/ESA Hubble Space Telescope, reveals a star in the process of forming within the Chameleon cloud. This young star is throwing off narrow streams of gas from its poles — creating this ethereal object known as HH 909A. These speedy outflows collide with the slower surrounding gas, lighting up the region. Credit: NASA & ESA #nasagoddard #hubble #hst #space #star #cloud
