Several days ago, the Calbuco volcano erupted for the first time in nearly 50 years, and it did so with quite a vengeance.

Scientists Generate Broadband Terahertz Radiation from Microplasma in Air

A microplasma is created by focusing intense laser pulses in ambient air with a microscope objective in the lab of University of Rochester Institute of Optics Researchers at the University of Rochester’s Institute of Optics have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation.

Kornmesser/Nick Risinger) Despite the fact that helium is one of the most abundant elements in the universe, its existence wasn’t known until 1868, when Pierre Janssen—a french physicist and mathematician—accidently stumbled across strange spectral lines in the Sun’s light during a solar eclipse.

10 Solutions to the Fermi Paradox

Tentatively finding even the most faint sign of extraterrestrial life would be the single most important discovery in the history of mankind, it could possibly help us find answers to the most existential mysteries of science, like “how did life on Earth arise,” and, more importantly, “are we alone?
