This supercomputer simulation shows one of the most violent events in the universe: a pair of neutron stars colliding, merging and forming a black hole. A neutron star is the compressed core left behind when a star born with between eight and 30 times the sun's mass explodes as a supernova. Neutron stars pack about 1.5 times the mass of the sun — equivalent to about half a million Earths — into a ball just 12 miles (20 km) across.
As the simulation begins, we view an unequally matched pair of neutron stars weighing 1.4 and 1.7 solar masses. They are separated by only about 11 miles, slightly less distance than their own diameters. Redder colors show regions of progressively lower density.
As the stars spiral toward each other, intense tides begin to deform them, possibly cracking their crusts. Neutron stars possess incredible density, but their surfaces are comparatively thin, with densities about a million times greater than gold. Their interiors crush matter to a much greater degree densities rise by 100 million times in their centers. To begin to imagine such mind-boggling densities, consider that a cubic centimeter of neutron star matter outweighs Mount Everest.
By 7 milliseconds, tidal forces overwhelm and shatter the lesser star. Its superdense contents erupt into the system and curl a spiral arm of incredibly hot material. At 13 milliseconds, the more massive star has accumulated too much mass to support it against gravity and collapses, and a new black hole is born. The black hole's event horizon — its point of no return — is shown by the gray sphere. While most of the matter from both neutron stars will fall into the black hole, some of the less dense, faster moving matter manages to orbit around it, quickly forming a large and rapidly rotating torus. This torus extends for about 124 miles (200 km) and contains the equivalent of 1/5th the mass of our sun.
Scientists think neutron star mergers like this produce short gamma-ray bursts (GRBs). Short GRBs last less than two seconds yet unleash as much energy as all the stars in our galaxy produce over one year.
The rapidly fading afterglow of these explosions presents a challenge to astronomers. A key element in understanding GRBs is getting instruments on large ground-based telescopes to capture afterglows as soon as possible after the burst. The rapid notification and accurate positions provided by NASA's Swift mission creates a vibrant synergy with ground-based observatories that has led to dramatically improved understanding of GRBs, especially for short bursts.

The Aberdeen Proving Ground (APG) Centennial Gala, held Friday, October 20, in Aberdeen was the culminating event of a year-long celebration of APG’s 100th Anniversary. Approximately 780 people attended the Cabaret-themed event, which featured live music, a casino, dancing, comedy, fireworks, acrobats and other performers, and an After-Party at the Speakeasy. Merritt Property, which manages the Aberdeen Corporate Park on route 22 next to the Target store, donated the use of the 90,000-square foot building for the event. U.S. Congressman Dutch Ruppersberger, MG Randy Taylor, local and state elected officials, and senior Army officials were in attendance, as were hundreds of members of the Harford and Cecil County communities.
The Gala was hosted by the APG Centennial Celebration Association, which is working to establish the APG Discovery Center in Aberdeen. This facility will house an interactive STEM educational space for learners of all ages to experience science and technology through hands-on exhibits and demonstrations.
During 2017, the APG community hosted over 150 events during 2017 to commemorative APG’s 100-year history. The Live Fire, the APG Memorial dedication, the Rosie the Riveters movie, exhibits at the college and libraries, historical talks and presentations, and Science Cafes.
Bravura Information Technologies was the presenting sponsor of the event. Additional funding was provided by Harford County Office of Economic Development, APG Federal Credit Union, SURVICE Engineering, Harford Community College, AFCEA, IRA, Association of Old Crows, Tenax Technologies, Northeastern Maryland Technology Council, Veteran Corps of America, Profile Partners, Leidos, Cray Supercomputers, CACI, ManTech, Jacobs, Adams Communication, Booz Allen, Camber, Jones Junction Greater Harford Committee, Signatech, Cecil College and many more businesses.
Now, some people might think these switches controlled the vast array of lights in the dining room. Actually, these switches were binary programming toggles for an old Cray supercomputer which was housed in a still-active subterranean bunker. Er, correction, they were just to control the dining room lights.
It should come as no surprise that this entire area has been thoroughly illegally scrapped for its copper since then.

This is a supercomputer, used to perform extremely complex calculations such as the effects of a nuclear weapon, or the changes brought on by global warming.
Dr. Guang Gao, a distinguished professor of electrical and computer engineering, along with Professor Roberto Giorgi, an associate professor at the Università degli Studi di Siena in Siena, Italy and primary investigator (Coordinator / Scientific Manager) of the TeraFlux project. The TeraFlux project seeks to exploit dataflow parallelism in teradevice computing and propose a complete solution to harness large-scale parallelism in an efficient way. The University of Delaware recently joined the TeraFlux project and received a grant connected to the project from the EU.
