Scientists know that dark matter exists because although we can’t see it, we can see the effects of what it does in the world, sort of like a ghost bumping around a haunted house. And we’re not sure w...
Scattered across our Milky Way galaxy are tens of millions of black holes — immensely strong gravitational wells of spacetime, from which infalling matter, and even light, can never escape. Black hole...
The Large Underground Xenon (LUX) dark matter experiment, which operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its searc...
On the heels of their participation in the historic research that resulted in the detection of gravitational waves, West Virginia University astrophysicists continue to plow new ground ...
We evaluate a s2 statistic to test against the Homestake data the hypothesis that the neutrino Ñux from the Sun is constant. We use estimates of standard deviations derived 1000 simulations of t...
Results of the XENON100 experiment are a bright spot in the search for dark matter.The team of international scientists involved in the project demonstrated the sensitivity of their detector...
The National Science Foundation’s Green Bank Telescope (GBT) will join in the most powerful, comprehensive, and intensive scientific search ever for signs of intelligent life in the Universe. The inte...
Seeking to expand how we observe and understand the universe where we live, the National Science Foundation today helped dedicate the Advanced Laser Gravitational Wave Observatories (Advanced LIGO) at...
We discovered a large-scale shell G53.9+0.2 around the Crab-like pulsar wind nebula (PWN) G54.1+0.3 with 1420 MHz continuum Very Large Array observations. This is confirmed by a new infrared (IR) imag...
We present 12 CO J = 1 → 0 observations of ultraluminous infrared galaxies (ULIRGs) obtained using the Redshift Search Receiver (RSR) on the 14 m telescope of the Five College Radio Astronomy Observat...
The 3 mm wavelength spectra of 10 galaxies have been obtained at the Five College Radio Astronomy Observatory using a new, very broadband receiver and spectrometer, called the Redshift Search Receiver...
A sensitive search for pulsars has been conducted using the 92-meter transit telescope of the National Radio Astronomy Observatory. Nearly 50% of the sky north of +20(DEGREES) declination was searched...
COLUMBUS, Ohio—A newly discovered planet in a binary star system located 3,000 light-years from Earth is expanding astronomers’ notions of where Earth-like—and even potentially habitable—planets can f...
The first dedicated search for ultra-high energy (UHE) tau neutrinos of astrophysical origin was performed using the IceCube detector in its 22-string configuration. The search also had sensitivity to...
We report on the first X-ray images of the Phoenix dwarf galaxy, taken with \emph{XMM-Newton} in July 2009. This local group dwarf galaxy shares similarities with the Small Magellanic Cloud (SMC) incl...
