Physicists from the Massachusetts Institute of Technology (MIT) are one step closer to measuring the mass of the elusive neutrino, developing a new tabletop particle detector capable of identifying single electrons in a radioactive gas by trapping them in a magnetic bottle.

“Dark energy” used to only be a buzzword used by psychics. Now, though, it's picking up steam in physics, too.

About 1/4 of the universe is composed of dark matter, so it’s kind of a big deal. But do you know what it is?

All the way from the South Pole, new research results from the Niels Bohr Institute have opened the world’s eyes about neutrinos—a type of particle that passes through everything in our universe—by calculating the physical properties of these exotic yet forgotten particles.

In Star Wars, the Death Star is a massive spaceship capable of destroying a planet with just one shot of its laser, but a recently-discovered white dwarf star may have ripped apart a planet at its core by coming too close to it, making it a real-life Death Star.

By observing colliding galaxies with the ESO’s Very Large Telescope (VLT) and the Hubble Space Telescope, astronomers have found evidence suggesting for the first time that dark matter may interact with other dark matter in a way other than through gravity.

Chuck Bednar for redOrbit.com - @BednarChuck After two years worth of work by some 300 researchers, the Dark Energy Survey (DES) project have unveiled the first in a series of dark matter maps showing the distribution of the mysterious substance experts believe makes up roughly 27 percent of the universe. According to BBC News, the maps show how conglomerations of dark matter change over time and was created using a 570-megapixel camera attached to the Victor Blanco telescope in Chile....

A new survey by the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory studied 72 galactic cluster collisions from all different angles and times, revealing that the 85 percent of the universe’s total matter is way weirder than we could ever imagine.

Astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought, narrowing down what this crazy substance might be.

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...
