Dark Energy Survey Will Look For Supernovae
2013-07-01 18:32:12

The greatest cosmological puzzle of the 21st century continues to be to measure, characterize and understand the source of dark energy – the apparent force that is driving the accelerating expansion of the Universe.

How Does Hydrogen Drive Star Formation In Galaxies
2013-06-13 05:00:58

A major field of study in astronomy seeks to understand how galaxies form and evolve. One advantage that we possess is that as we study the light from the most distant galaxies, we are effectively looking back in time, seeing the oldest galaxies in the Universe when they were still young.

Supernova Light Echo Detected
2013-06-05 13:28:46

Astronomers discovered light echoing off of material surrounding a recent supernova explosion, supporting the theory that exploding white dwarfs become unstable from matter donated by large non-degenerate stars.

Hubble Helps Astronomers Map Ejected Supernova Material In 3D
2013-06-04 12:22:13

Astronomers using NASA's Hubble Space Telescope have mapped out a 3D structure of material ejected from an exploding star.

Earth's Neighborhood In The Milky Way Sits On Spiral Arm, Not Spur
2013-06-03 14:49:23

New research using the ultra-sharp radio vision of the National Science Foundation's Very Long Baseline Array (VLBA) has determined that we live in a more upscale neighborhood in our galaxy than previously thought.

Mystery Of Nearby SS Cygni Star System Finally Resolved
2013-05-23 13:22:47

Scientists have finally resolved the mystery over the distance and measured brightness of a nearby star system known as SS Cygni.

Young Universe Was A Massive Factory For Star Formation
2013-04-17 13:36:09

Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old.

Hubble Space Telescope Breaks Record For Furthest Supernova
2013-04-04 12:49:29

The NASA/ESA Hubble Space Telescope has broken the record in the quest to find the furthest supernova of the type used to measure cosmic distances.

Astronomers Identify New Type Of Supernova 100 Times More Massive Than Our Sun
2013-03-26 13:30:57

Astronomers discovered a new type of supernova of a star about 10 to 100 times more massive than our sun.

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...
