The highest-energy light ever seen hails from the Crab Nebula

Posted by in categories: cosmology, particle physics

Physicists have spotted the highest-energy light ever seen. It emanated from the roiling remains left behind when a star exploded.

This light made its way to Earth from the Crab Nebula, a remnant of a stellar explosion, or supernova, about 6,500 light-years away in the Milky Way. The Tibet AS-gamma experiment caught multiple particles of light — or photons — from the nebula with energies higher than 100 trillion electron volts, researchers report in a study accepted in Physical Review Letters. Visible light, for comparison, has just a few electron volts of energy.“This energy regime has not been accessible before,” says astrophysicist Petra Huentemeyer of Michigan Technological University in Houghton, who was not involved with the research. For physicists who study this high-energy light, known as gamma rays, “it’s an exciting time,” she says.

Hypersonic Missiles Are Unstoppable. And They’re Starting a New Global Arms Race

Posted by in category: military

The arrival of such fast weaponry will dangerously compress the time during which military officials and their political leaders — in any country — can figure out the nature of an attack and make reasoned decisions about the wisdom and scope of defensive steps or retaliation. And the threat that hypersonics pose to retaliatory weapons creates what scholars call “use it or lose it” pressures on countries to strike first during a crisis. Experts say that the missiles could upend the grim psychology of Mutual Assured Destruction, the bedrock military doctrine of the nuclear age that argued globe-altering wars would be deterred if the potential combatants always felt certain of their opponents’ devastating response.

At War

The new weapons — which could travel at more than 15 times the speed of sound with terrifying accuracy — threaten to change the nature of warfare.

SpaceX launches hefty rocket with 24 satellites

Posted by in categories: energy, military, satellites

CAPE CANAVERAL, Fla. (AP) — SpaceX launched its heftiest rocket with 24 research satellites Tuesday, a middle-of-the-night rideshare featuring a deep space atomic clock, solar sail, a clean and green rocket fuel testbed, and even human ashes.

It was the third flight of a Falcon Heavy rocket, but the first ordered up by the military.

The Defense Department mission, dubbed STP-2 for Space Test Program, is expected to provide data to certify the Falcon Heavy — and reused boosters — for future national security launches. It marked the military’s first ride on a recycled rocket.
