Stephen Hawking Touches On God And Dark Matter At Caltech Speech
2013-04-18 11:09:45

Although he probably never expected a career in physics would warrant it, Stephen Hawking received a ‘rock star’ reception to his speaking engagement at the California Institute of Technology (Caltech) in Pasadena, California on Tuesday.

Evidence Of Dark Matter In WIMP Experiment
2013-04-16 09:16:50

An international collaboration of scientists has, for the first time, observed a concrete hint of a WIMP – weakly interacting massive particle – which physicists believe could be behind the mysterious phenomenon of dark matter.

Blue Supergiant Star Born In The Wild Discovered
2013-04-11 15:09:53

A duo of astronomers has discovered a Blue Supergiant star located far beyond our Milky Way Galaxy in the constellation Virgo

Scientists Discover The Earliest Known Starburst Galaxies In The Universe
2013-04-05 15:32:28

An international team of researchers announced it has found some of the universe’s earliest starburst galaxies, essentially young energetic clusters of cosmic gas and dust that form stars at an alarming rate.

Kepler Data Shows Light-bending Gravity In Action
2013-04-05 08:44:27

NASA's Kepler space telescope has observed the effects of a dead star bending the light of its companion star, one of the first detections of this phenomenon in double star systems.

Evidence That Dark Matter Is Real
2013-04-04 05:36:28

For decades scientists have wondered whether a mysterious form of matter – known simply as Dark Matter since it does not interact directly with light – makes up the majority of the “stuff” in the Universe.

Probes Of Dark Matter On Galaxy Scales 2013
2013-04-03 19:01:07

Scientists are coming together this summer to try and collaborate on solving the mystery of dark matter.

Cosmic Journey 13 Billion Years In The Making Seen By Plank
2013-04-02 11:43:48

Cosmologists using data from ESA's Planck satellite have compiled the first all-sky image of the distribution of dark matter across the entire history of the Universe as seen projected on the sky.

Gravitational Lensing In The Unusual "Magatama" Galaxy
2013-04-01 09:37:32

In a course of studying young galaxies at a distance of 11.6 billion light years from Earth, a team of astronomers noticed a strangely shaped galaxy that looks like a "magatama", an ancient, comma-shaped Japanese amulet made of stone.

Starburst Galaxies Observations Reveal They Occured Earlier In Universe Than Previously Believed
2013-03-13 14:29:45

Scientists making observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope say they have found that the most vigorous bursts of star birth in the universe actually took place earlier than previously thought.

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...
