A team of researchers used telescopes around the world to study the most massive neutron star confirmed so far, orbited by a white dwarf. The scientists wrote in the journal Science that so far the new observations match up with Einstein's predictions for general relativity.
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.
The densest matter in the Universe outside of black holes is contained in neutron stars, the ultra-dense cores left behind after massive stars collapse. One of the most reliable determinations yet of the relationship between the radius of a neutron star and its mass has been provided by new results led by the Chandra Observatory.
NASA’s Fermi Gamma-ray Space Telescope, the most advanced space-based gamma-ray mission ever launched is turnings its eye to the problem of dark matter.
Researchers reported in the journal Physical Review Letters that they have found a "glitch" in a 40-year-old theory explaining the periodic speeding up or "glitching" of pulsars.
European Renaissance printers probably knew they were recording history for future generations, but what they didn’t realize is that they were also recording events related to biological history.
Nearly a mile underground beneath the Black Hills of South Dakota, scientists from Lawrence Livermore National Laboratory (LLNL) are using a tank to make key contributions to a physics experiment that will look for one of nature's most elusive particles, "dark matter."
The intimate details of 100 galaxies in the local universe have been published by the Calar Alto Legacy Integral Field Area survey (CALIFA).
Astronomers using simulations were able to catch the Large Magellanic Cloud in the act of stealing stars away from its neighbor, the Small Magellanic Cloud.
Astronomer J. Craig Wheeler reports in The Astrophysical Journal that he has a new theory on the identity of the "parents" of Type Ia supernovae.
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...
