The generation of coherent extreme ultraviolet and X-ray photons by high harmonic generation from solid targets relies on the formation of a steep electron density gradient tuned by the leading edge of a relativistically intense laser pulse interacting with a bulk, solid-density target.

The Lyrid shower is among the oldest recorded meteor showers, dating back as far as 2,700 years. The meteor shower is visible when Earth travels through the path of Comet Thatcher, rendering a trail of the comet's remnants visible to skywatchers.

"A stellarator is a thing that is objectively very difficult to design, objectively very difficult to build, but if it works, it can control the burning hot plasma better than a tokamak."

"There are examples of balls that transfer high or low energy through all eras of play. There is no trend that suggests the magnitude of energy transfer is increasing or decreasing over time."

Energy Secretary Chris Wright stated, 'A lot of the nuclear security scientists are in DOE. So yes, of course we are looking into this.' He confirmed that the investigation is part of a broader inquiry involving multiple government branches.

The new Samuel Oschin Air and Space Center, designed by ZGF Architects, is a 200,000-square-foot addition that will nearly double the Science Center's educational exhibit space.

The Minamitorishima operation, conducted with the scientific deep-sea drilling vessel Chikyu, represents the world's first attempt to sample at such depths.

Inside the Natick Soldier Systems Center, the US Army puts its own gear through extreme tests, including burning uniforms and freezing equipment, to ensure durability.
