Non-Astronomy Scientists May Help Answer Cosmology Conundrum
2013-11-28 06:41:07

Measuring the invisible and intangible is a challenge for sure, but scientists have made inroads on one front: the study of dark matter and dark energy, two of the most mysterious substances in our cosmos.

Ancient Brown Dwarfs

New research has found the two oldest brown dwarfs in the galaxy, and they have a somewhat unexpected property: they move extremely fast.

Axion Search For Dark Matter
2013-11-07 08:36:41

A research team is hunting for a theorized but never-before-seen elementary particle called an axion that may be at the heart of dark matter.

LUX Dark Matter Detector Finds Nothing Yet

Just three months into its operation, the Large Underground Xenon experiment is already the most sensitive dark matter detector in the world.

Experiment Looks For Dark Matter Particle

MIT physicists have proposed a new experiment to look for the elusive dark matter particle known as the 'A Prime' particle.

Hubble, Spitzer And Chandra Team Up For Frontier Fields Mission

In an ambitious new project, NASA officials are looking to combine three of the agency’s most powerful space telescopes in what is being called the deepest probe of the universe ever attempted.

Colliding Galaxies Create Supermassive Black Holes

At the center of almost every galaxy we have studied is a black hole of such magnitude that the traditional black hole progenitor does not seem likely. These aptly named supermassive black holes can reach millions or billions of times the mass of our Sun.

Twisted Path Ancient Light Mapped

When astronomers peer into the deepest regions of the cosmos they are not seeing the Universe as it exists today, but rather how it looked billions of years ago.

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...
