Several days ago, the Calbuco volcano erupted for the first time in nearly 50 years, and it did so with quite a vengeance.
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.
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?
Another dimension: Professor Marc in het Panhuis and PhD student Shannon Bakarich are building objects using 4-D printing, where time is the fourth dimension.
Since it went into orbit, piggybacking on the Discovery Space shuttle in the spring of 1990, the Hubble Space Telescope has revolutionized nearly everything that we know about our universe.
Pointing telescopes towards the heavens is not an arbitrary practice. It’s not something that we do just to see pretty things.

This NASA/ESA Hubble Space Telescope image of the cluster Westerlund 2 and its surroundings has been released to celebrate Hubble’s 25th year in orbit The Hubble Space Telescope is turning 25 tomorrow, and in celebration of this day, NASA and the ESA are focusing the telescope in on some of the most astounding features in our universe.

If scientists, specialists, researchers, teachers, and basic scientific facts won’t convince you that vaccines are beneficial, well, maybe Elmo will.
Individual electrons measured by the detector – (Image by the researchers, via MIT) A longstanding mystery of particle physics may soon be solved, thanks to a surprisingly compact new particle detector developed at the Massachusetts Institute of Technology (MIT).

Dartmouth astrophysicists and their colleagues have not only proven that a supermassive black hole exists in a place where it isn’t supposed to be, but in doing so have opened a new door to what things were like in the early universe.
