Latest Exotic matter Stories
Sometimes when you're looking for one thing, you find something completely different and unexpected.
Ever since audiences heard Goldfinger utter the famous line, â€œNo, Mr. Bond; I expect you to die,â€ as a laser beam inched its way toward James Bond and threatened to cut him in half, lasers have been thought of as white-hot beams of intensely focused energy capable of burning through anything in their path.
The existence of Dark Matter particles in the Sun's interior seems inevitable, despite dark matter never having been observed (there or elsewhere), despite intensive ongoing searches.
When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe rewriting some of the assumptions of physics.
A team of European researchers have pinpointed a magnetar--an unusual type of neutron star that possesses an immensely powerful magnetic field.
This month physicist Juan Collar and his associates are taking their attempt to unmask the secret identity of dark matter into a Canadian mine more than a mile underground.
Scientists leading an underground experiment to discover dark matter may be forced to relocate to a location even deeper below the Earth's surface.
The question of what causes a Type Ia supernova is one of the great unsolved mysteries in astronomy.
Neutrinos are likely half as massive as previous estimates suggested.
A sensitive measuring device must not be dropped - because this usually destroys the precision of the instrument.
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...
