A research team led by astronomers and astrophysicists at the University of Warwick have found that some of the Universe’s loneliest supernovae are likely created by the collisions of white dwarf stars into neutron stars.

The new PandaX facility, located deep underground in the southwestern Chinese province of Sichuan, hosts a large liquid-xenon detector designed to search for direct evidence of dark matter interactions with the nuclei of xenon and to observe 136Xe double-beta decay.

From the physics labs at Yale University to the bottom of a played-out gold mine in South Dakota, a new generation of dark matter experiments is ready to commence.

The PandaX experiment of China, which is located in the deepest underground laboratory, has released its technical design report recently.

Using the ESA’s XMM-Newton and NASA’s Chandra X-ray Observatory, astronomers have located a mysterious X-ray signal that could be produced by sterile neutrinos – particles that are a potential candidate for the abundant and essentially invisible substance known as dark matter.

Astronomers Discover Bizarre Type Of Hybrid Star
2014-06-05 03:57:41

In a discovery decades in the making, scientists have detected the first of a “theoretical” class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Żytkow.

Pulsating X-rays Allow XMM-Newton To Reveal A Mysterious Star
2014-06-04 03:32:58

XMM-Newton has revealed a unique star. It is a celestial chimera with the body of a normal massive star yet the magnetic field of a dead, stellar dwarf. This makes it a singular object among the billions of known stars.

Have Experts Finally Solved The Mystery Of Magnetars?

When a massive star reaches the end of its life, it explodes in a brilliant supernova explosion. The remnant of the stellar core will usually form either a neutron star or a black hole.

Brightening Star Offers Astronomers New Way To Study Binary Systems
2014-04-22 10:48:49

Researchers searching for planets orbiting around a distant star look for a signature dimming of that star’s light, but what if the distant star suddenly gets a bit brighter?

Syracuse University Plays Key Role In Search For Elusive Dark Matter
2014-04-11 13:31:00

Physicist Richard Schnee hopes to find traces of dark matter by studying particles with low masses and interaction rates, some of which have never been probed before

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

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
2004-10-19 04:45:42

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...
