For decades it was baffling. Out of the still night sky, astronomers peering through their telescopes would occasionally glimpse quick bursts of high-energy light popping off like flashbulbs at the far side of the universe. These bursts seemed impossibly powerful: to appear so bright from so very far away, they must vastly outshine entire galaxies containing hundreds of billions of stars. These explosions, called gamma ray bursts (GRBs), are by far the brightest and most energetic phenomena...

By Kevin Sieff, The Brownsville Herald, Texas Jun. 17--Ten years ago, the University of Texas at Brownsville and Texas Southmost College lacked even a basic physics department. Now, the university's Center for Gravitational Wave Astronomy is world renowned, its students and professors at the cutting edge of international research. In the most recent of the program's accolades, four UTB-TSC physics professors have been selected to teach Chinese scientists and graduate students about their...

ESA's orbiting gamma-ray observatory, Integral has revealed a new population of exotic and dusty binary stars which might represent a brief evolutionary period in a binary star's life. The findings bring to light a gap in our knowledge of the formation and evolution of such binary star systems. Since 2002, when Integral was launched, the observatory has been surveying the galaxy, looking for sources of the most powerful X-rays and gamma rays. Fifteen of its new discoveries appeared to be...

New information about the heart of one of the most famous objects in the sky -- the Crab Pulsar in the Crab Nebula -- has been revealed by an international team of scientists searching for gravitational waves. The team's achievement also is the first direct look into the interior of a neutron star.The research team detected signals from the pulsar -- a rapidly spinning neutron star -- with the Laser Interferometer Gravitational-Wave Observatory (LIGO). The analysis of the signals reveals that...

Aim to produce new generation of astronomer that understands theory and observationThe future of fundamental physics research lies in observing the early universe and developing models that explain the new data obtained. The availability of much higher resolution data from closer to the start of the universe is creating the potential for further significant theoretical breakthroughs and progress resolving some of the most difficult and intractable questions in physics. But this requires much...

The U.S. Laser Interferometer Gravitational-wave Observatories (LIGO) is getting a $205 million upgrade by the National Science Foundation (NSF). Dubbed the "Advanced LIGO Project", the upgrade will enable the new field of gravitational wave astronomy. The National Science Board approved the seven-year project in its March 27 meeting, and the  NSF will provide an initial $32.75 million in funding this year via the Major Research Equipment and Facilities Construction (MREFC) budget...

But gravitational waves may be more sensitive probe of early universe physics than previously thoughtA team of researchers from Case Western Reserve University has found that gravitational radiation"”widely expected to provide "smoking gun" proof for a theory of the early universe known as "inflation""”can be produced by another mechanism. According to physics scholars, inflation theory proposes that the universe underwent a period of exponential expansion right after the big...

The same team of astrophysicists that cracked the computer code simulating two black holes crashing and merging together has now, for the first time, caused a three-black-hole collision.Manuela Campanelli, Carlos Lousto and Yosef Zlochower"”scientists in Rochester Institute of Technology's Center for Computational Relativity and Gravitation"”simulated triplet black holes to test their breakthrough method that, in 2005, merged two of these large mass objects on a supercomputer...

Scientists hope that a new supercomputer being built by Syracuse University's Department of Physics may help them identify the sound of a celestial black hole. The supercomputer, dubbed SUGAR (SU Gravitational and Relativity Cluster), will soon receive massive amounts of data from the California Institute of Technology (Caltech) that was collected over a two-year period at the Laser Interferometer Gravitational-Wave Observatory (LIGO). LIGO is funded by the National Science Foundation and...

Picture the Milky Way galaxy -- a disk of stars and gas, a stellar spheroid and an enormous halo of dark matter. It spirals around a black hole that is supermassive-about three million solar masses. The Milky Way's total mass is about 100 billion solar masses-enormous to us but average among galaxies. Then imagine that galaxy encountering its identical twin. The first galaxy merges with the second to produce a galaxy that's even grander and greater. Cosmologists think that's how galaxies...

Word of the Day
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
