Iron 'Fingerprints' Point Astronomers To Supernova Remnants
2014-07-03 03:27:00

An international team of astronomers using data from the Japan-led Suzaku X-ray observatory has developed a powerful technique for analyzing supernova remnants, the expanding clouds of debris left behind when stars explode.

Many of the oldest and most massive galaxies reside together in enormous structures known as clusters, and now a team of astronomers has confirmed the existence of an unusually distant galaxy cluster.

Supernovae Used To Gauge The Power Of Cosmic Lenses

Scientists using the NASA Hubble Space Telescope found that the Large Magellanic Cloud (LMC) completes a rotation every 250 million years. The team used Hubble to measure the average motion of hundreds of individual stars in the nearby galaxy, which is located about 170,000 light-years away from Earth.

The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...
