Latest Astroparticle physics Stories
Predicting solar flares still remains a hit-or-miss task for scientists, but new research may shed more light on helping to predict just when the events could occur.
Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are annihilating each other in space.
"If dark matter is a fundamental particle, billions of these particles will have passed through your body by the time your finish reading this article. - George Lake"
In August, physicists will gather to celebrate a century of research since the discovery of cosmic rays.
Scientists from the XENON collaboration announced a new result from their search for dark matter.
Scientists have determined that previously undetected particles could be seen as they accumulate around black holes.
NASA said that its Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun on March 7.
According to a new study, large amounts of dark matter do not surround the Sun, despite some widely accepted theories.
There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies.
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...
