The aircraft is one of Northrop Grumman’s best models.

The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning aircraft. Its latest and most advanced version is the E-2D Advanced Hawkeye.

which features the AN/APY-9 radar (capable of detecting fighter-sized stealth aircraft), radio suite, mission computer, integrated satellite communications, flight management system, improved T56-A-427A engines, a glass cockpit and aerial refueling.


Using the Large Phased Array (LPA) radio telescope of Pushchino Radio Astronomy Observatory (PRAO) in Russia, astronomers have detected seven new pulsars and determined their basic parameters. The finding is reported in a paper published August 18 on the arXiv pre-print repository.

Pulsars are highly magnetized, rotating emitting a beam of electromagnetic radiation. They are usually detected in the form of short bursts of radio emission; however, some of them are also observed via optical, X-ray and gamma-ray telescopes.

Now, a group of Russian astronomers led by PRAO’s Sergey Tyul’bashev reports the detection of seven new pulsars. The discovery was made with LPA as part of a daily sky survey conducted in a test mode, covering a full day in right ascension and 50 degrees in declination. The new pulsars were detected at a frequency of 111 MHz.

Today it only takes one and a half hours to make a superconducting particle accelerator at the Department of Energy’s SLAC National Accelerator Laboratory colder than outer space.

“Now you click a button and the machine gets from 4.5 Kelvin down to 2 Kelvin,” said Eric Fauve, director of the Cryogenic team at SLAC.

While the process is fully automated now, getting this accelerator, called LCLS-II, to 2 Kelvin, or minus 456 degrees Fahrenheit, took six years of designing, building, installing, and starting up an intricate system.
