Astronomers Asking Volunteers To Help Find 'Space Warps'
2013-05-08 12:46:13

Space warps are more commonly known as "gravitational lenses," which allows objects in space to act as a giant lens to other objects even farther away. Studies have found that the human brain is much better at identifying lenses than current computer algorithms, so astronomers are asking volunteers to participate in the Space Warps project.

Black Hole Birth In A Cosmic Flash

Stars sustain themselves by fusing elements in their core, producing even heavier atoms, releasing energy that keeps the immense force of gravity at bay. But eventually, the fusion process will no longer produce enough outward radiation pressure to sustain the star, and it will begin to collapse in on itself.

Blowing Bubbles: The Hunt For Dark Matter Is On At SNOLAB
2013-05-03 05:07:09

A new dark matter experiment is underway in which dark matter particles could potential be directly measured. The experiment, known as COUPP-60, sits a mile and a half underground in Ontario, Canada.

Cosmic Test Upholds Einstein's Theory Of General Relativity

A team of researchers used telescopes around the world to study the most massive neutron star confirmed so far, orbited by a white dwarf. The scientists wrote in the journal Science that so far the new observations match up with Einstein's predictions for general relativity.

White Dwarf Search May Yield Habitable Planets

A dead star, known as a white dwarf, will eventually cool down and fade away because it has no energy source. However, a new study suggests that white dwarfs can still support habitable planets.

Stephen Hawking Touches On God And Dark Matter At Caltech Speech

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

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.

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.

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...
