Lead Ingots From Shipwrecks Being Used To Hunt For Dark Matter
2013-12-02 08:18:12

Albeit with much controversy, physicists are using ancient lead ingots from sunken ships in the study of dark matter in neutrinos. Archaeologists have gone on the offensive, expressing concerns over the destruction of underwater cultural heritage.

Neutron Star Mystery Heats Up

New research appearing in the latest edition of the journal Nature is casting doubts on currently accepted theories has to how the surface of a neutron star heats itself up.

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

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...
