Latest Dark matter Stories
Observational of distant galaxies suggests one of two possibilities: either these galaxies contain significantly more mass than what is seen, or our physical understanding of gravity is flawed.
The neutrino plays a crucial role in nuclear processes such as fusion. But because of its small mass and neutral charge, it is very difficult to measure and study and as a result has been a source of frustration to physicists and astronomers.
A recent nova, located in the constellation Delphinus, is the brightest such event since 2007 and is visible with the naked eye, assuming the observer is in a relatively dark location away from city lights.
The best way to solve a mystery, as any detective can tell you, is to revisit the scene where it began and look for clues. Scientists, searching for the mysteries of our universe, are trying to go back as far as they can to the Big Bang.
Today, researchers at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) released the first image of the Andromeda Galaxy (M31) processed with the data analysis software developed for the Subaru Telescope's Hyper Suprime-Cam (HSC).
In the hunt for dark matter and dark energy, researchers now have a new weapon in their arsenal: the Hyper-Suprime Cam (HSC).
New observations have given a group of astronomers the best view yet of how star formation regions can get selfish and gassy.
International research including the UK and Japan has confirmed that subatomic particles called neutrinos have a new form of identity-shifting property.
Neutrinos are the most elusive particles having extremely weak interactions with all other particles.

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...
