Using one of the most sensitive neutrino detectors on the planet, an international team including physicists Laura Cadonati and Andrea Pocar at the University of Massachusetts Amherst are now measuring the flow of solar neutrinos reaching earth more precisely than ever before.
Researchers at the CRESST II experiment in Italy say they may have seen more hints of dark matter.
Older stars may have to slow down their rotations before exploding as supernovae.
They were always mysterious.
Type Ia supernovae are violent stellar explosions whose brightness is used to determine distances in the universe.
Science Channel's "Through The Worm Hole" will be airing its new episode "Can We Travel Faster Than Light?" on Wednesday July 20th in classic mind-blowing style.
Astronomers have discovered a pair of white dwarfs spiraling into one another at breakneck speeds.
Yet another independent line of evidence points to the dominance of dark matter in galaxy clusters.
An international research team led by Japan and that includes the University of Colorado Boulder may have taken a significant step in discovering why matter trumped antimatter at the time of Big Bang, helping to create virtually all of the galaxies and stars in the universe.
KICP's Juan Collar leads a team that detected a seasonal signal variation compatible with dark matter theory.
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....
White Dwarf -- A white dwarf is a a star supported by electron degeneracy. A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star goes through a red giant phase and then expels most of its outer material (creating a planetary nebula) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf. A typical white dwarf is half as massive as the Sun, yet only...
Supernova -- A supernova is a star that increases its brightness drastically within a matter of days, making it appear as if a "new" star was born (hence "nova"). The "super" prefix distinguishes it from a mere nova, which also involves a star increasing in brightness, though to a lesser extent and through a much different mechanism. Astronomers have classified supernovae in several classes, according to the lines of different elements that appear in their spectra. The first element...
Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...
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...
