Cosmic Rays Influence Cloud Formation
2013-09-05 08:39:02

A new study has resurrected the hypothesis that cosmic rays may influence cloud formation on Earth.

Cosmic Rays Origins
2013-08-30 11:25:08

Streaming across the Universe are high-energy charged particles, known as cosmic rays. For more than their origins have remained a mystery.

Mexico Observatory To Hunt For Gamma Rays In Known Universe
2013-08-22 07:35:15

A new observatory has begun formal operations in Mexico. The High-Altitude Water Cherenkov Gamma Ray Observatory is designed to study the origin of very high-energy cosmic rays and observe the most energetic objects in the known universe.

Dark Matter Not Actually Dark

New research is building upon the notion that dark matter may be Majorana particles, and suggests that perhaps dark matter can interact electromagnetically after all – meaning that dark matter may not be ‘dark’ after all.

Extragalactic Ankle And Galactic Knee
2013-06-03 17:42:35

It is obvious from the data of the KASCADE-Grande experiment at the Karlsruhe Institute of Technology (KIT) that the so-called “knee” of the cosmic rays, a bend in the energy spectrum at high energies, is located at different energies for light and heavy particles.

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.

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.

Evidence That Dark Matter Is Real
2013-04-04 05:36:28

For decades scientists have wondered whether a mysterious form of matter – known simply as Dark Matter since it does not interact directly with light – makes up the majority of the “stuff” in the Universe.

2013-03-18 20:49:50

AURA announced today that Dr. Steven M. Kahn will assume the role of Director of the Large Synoptic Survey Telescope (LSST) Project effective July 1, 2013.

New Cosmic Ray Telescope Hosted By Space Station
2013-03-12 15:44:52

The National Aeronautics and Space Administration has awarded $4.4 million to a collaboration of scientists at five United States universities and NASA’s Marshall Space Flight Center to help build a telescope for deployment on the International Space Station in 2017.

WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

Cosmic Rays -- Cosmic Rays. Cosmic rays are energetic particles that are found in space and filter through our atmosphere. Cosmic rays have interested scientists for many different reasons. They come from all directions in space, and the origination of many of these cosmic rays is unknown. Cosmic rays were originally discovered because of the ionozation they produce in our atmosphere. Cosmic rays also have an extreme energy range of incident particles, which have allowed physicists to...
