A Monash student has made a breakthrough in the field of astrophysics, discovering what has until now been described as the Universeâ€™s â€˜missing massâ€™.
Physicists at Rice University and their collaborators have detected the antimatter partner of the helium nucleus, antihelium-4.
An International team of scientists in the XENON collaboration, including several from the Weizmann Institute, announced on Thursday the results of their search for the elusive component of our universe known as dark matter.
WASHINGTON, March 24, 2011 /PRNewswire-USNewswire/ -- X-ray observations made by the Suzaku observatory provide the clearest picture to date of the size, mass and chemical content of a nearby cluster of galaxies.
Quantum physicists pave the way for investigating new states of matter in ultracold atom mixtures.
NASA said on Wednesday that its Chandra X-ray Observatory discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter at the core of a neutron star.
Using lasers to contain some ultra-chilled atoms, a team of scientists has measured the viscosity or stickiness of a gas often considered to be the sixth state of matter.
Type Ia supernovae (SNe Ia) play an important role as cosmological distance indicators and have been used successfully to determine cosmological parameters, which resulted in the discovery of the accelerating expansion of the Universe.
Researchers from the Institute for Corpuscular Physics (IFIC) and other European groups have studied the effects of the presence of dark matter in the Sun.
Search for ultra high energy neutrinos from space turns the moon into part of the 'detector'.
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...
