Red Dwarf Stars May Destroy Possibility Of Life In Their Systems
2013-07-01 18:43:05

About 75 percent of the main sequence stars in our galaxy are classified as red dwarf stars and they represent an exciting population to study in the search for life beyond Earth.

University Of Utah Joins Sky Survey’s Fourth Phase With W.L. Eccles Grant
2013-06-25 12:01:02

University of Utah astronomers will participate in a six-year project to study the formation of our Milky Way galaxy; map stars, gas and supermassive black holes in 10,000 neighbor galaxies; and chart 1 million galaxies and quasars to learn about mysterious “dark energy” that makes the universe expand.

New Hubble Image Shows Interacting Galaxies
2013-06-20 18:59:33

New images taken by the Hubble Space Telescope of a pair of galaxies experiencing a close encounter have been released.

Pulsating White Dwarf Discovered By UT Astronomers
2013-06-20 12:47:40

A group of astronomers have discovered pulsations from the crystallized remnant of a burnt-out white dwarf star.

Black Hole X Ray Mystery Solved
2013-06-14 14:00:15

Astronomers from several institutions have used decades-worth of collected data to confirm theories about how stellar-mass black holes produce their highest-energy light known as hard X-rays.

Project Maps Detailed Motions Of Universe
2013-06-14 11:35:29

An international team of researchers has created a map of the Universe near the Milky Way that better represents the physical dimensions of space. To accomplish this, the team created a video that allows for the perception of depth by rotating, zooming, and panning across the map space.

Data Supports Cold Model Dark Matter
2013-06-13 15:54:45

Researchers found that the density of the dark matter was greater near the center of the galaxy clusters, on average, gradually becoming more diffuse moving out towards the cluster’s edge. This is consistent with a cold dark matter model, which, along with other evidence, has been the leading candidate theory for some years.

Euclid Dark Matter Mission Now In Development
2013-06-11 13:13:58

The European Space Agency's Euclid module under development in France will be helping to explore dark energy and dark matter in the universe.

Dark Matter Not Actually Dark
2013-06-11 09:51:15

New research is building upon the notion that dark matter may be Majorana particles, and suggests that perhaps dark matter can interact electromagnetically after all – meaning that dark matter may not be ‘dark’ after all.

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies. Credit: NASA/Wikipedia What is Cosmology? I once commented to an acquaintance that I was fascinated by the field of Cosmology, and mused that if I had more time, I...

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...

The Bullet Cluster is made up of two colliding clusters galaxies. According to a 2006 study, the Bullet Cluster also shows the best evidence for the existence of Dark Matter. From observations of galaxy cluster collisions it has been found that many show displacement between their center of visible matter and their gravitational potential. Each component, stars, gas, and dark matter, within a cluster pair behaves differently during a collision allowing for each to be studied separately....

The Abell 520 galaxy cluster is an strange structure formed by a major merger. Due to its odd and chaotic nature it has been given the nick-name the Train Wreck Cluster. The Dark Matter within the cluster does not act as expected like it does in other clusters, therefore, Abell 520 creates problems for many of the prevailing theories about Dark Matter. It also disrupts many alternative theories of modified gravity. Similar to the Bullet Cluster the gas contents and galaxies within the...

The cluster CL0024+17, located in Pisces, is a galaxy cluster that is allowing astronomers to probe the distribution of dark matter in space. Dark matter does not reflect light and therefore cannot be seen. It is only detectable by the way its gravity affects the lights around it. Using gravitational lensing astronomers observe the distorted light around the dark matter and are able to tell where it is located within a cluster. A dark matter ring found near the cluster's center, by...
