Protest challenges small biz joint venture's structure -- Washington Technology


Protest challenges small biz joint venture s structure
Ascension Island is practically in the middle of nowhere.
Long under British control, the island sits in the middle of the Atlantic Ocean below the equator: 1,000 miles from the coast of Africa and 1,400 miles from the coast of Brazil.
Discovered in 1501, it was barren and populated by seabirds and turtles. The Portuguese introduced goats as a food source for mariners who would stop at the island.
The circle marks the location of Ascension Island in the Atlantic Ocean.
During World War II, it served as an airbase for American and British planes crossing the ocean. The island s military and government usage has continued since. The British used it during the Falklands War and the airstrip was an emergency landing strip for the Space Shuttle. ....

NANOGrav finds possible 'first hints' of low-frequency gravitational wave background


Credit: West Virginia University
In data gathered and analyzed over 13 years, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center (PFC) has found an intriguing low-frequency signal that may be attributable to gravitational waves.
NANOGrav researchers - including a number from West Virginia University s (WVU s) Department of Physics and Astronomy and the Center for Gravitational Waves and Cosmology - measure the times of arrival of radio pulses from exotic stars called pulsars with large radio telescopes, including the Green Bank Telescope (GBT) in Pocahontas County, West Virginia. Pulsars are small, dense stars that rapidly rotate, emitting beamed radio waves, much like a lighthouse. The results from this most recent dataset show perturbations in the arrival times from these pulsars that may indicate the effects of gravitational waves, as reported recently in ....

How the famed Arecibo telescope fell—and how it might rise again

On 1 December 2020, the 900-ton instrument platform of the Arecibo Observatory crashed into its dish, which is cradled in a natural sinkhole.

How the famed Arecibo telescope fell and how it might rise again
Jan. 14, 2021 , 11:52 AM
In the early morning of 10 August 2020, Sravani Vaddi, a postdoc astronomer at the Arecibo Observatory in Puerto Rico, was working from home, but her thoughts were at Arecibo’s giant radio telescope. At 2 a.m., she had one precious hour to focus the 305-meter dish on NGC 7469, a distant galaxy. At its center, two supermassive black holes wheeled around each other, following an earlier galaxy merger. Vaddi wanted to see whether having two dark hearts instead of the usual one made the galaxy shine more brightly by stirring up gases and stoking starbirth. Radio emissions from the glowing gases would help her find out. ....
