Ancient supernovae buffeted Earth’s biology with radiation dose, researcher says

Research published in April provided "slam dunk" evidence of two prehistoric supernovae exploding about 300 light years from Earth. Now, a follow-up investigation based on computer modeling shows those supernovae likely exposed biology on our planet to a long-lasting gust of cosmic radiation, which also affected the atmosphere.

Chernobyl: new tomb will make site safe for 100 years

Thirty years after the Chernobyl nuclear accident, there’s still a significant threat of radiation from the crumbling remains of Reactor 4. But an innovative, €1.5 billion super-structure is being built to prevent further releases, giving an elegant engineering solution to one of the ugliest disasters known to man.

Cosmic Beacons Reveal the Milky Way’s Ancient Core

An international team of astronomers led by Dr. Andrea Kunder of the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany has discovered that the central 2000 light years within the Milky Way Galaxy hosts an ancient population of stars. These stars are more than 10 billion years old and their orbits in space preserve the early history of the formation of the Milky Way.

Fast radio burst ‘afterglow’ was actually a flickering black hole

Last February a team of astronomers reported detecting an afterglow from a mysterious event called a fast radio burst, which would pinpoint the precise position of the burst's origin, a longstanding goal in studies of these mysterious events.

Lost lithium destroyed by ancient stars

Lithium, the lightest metal, used in batteries and mood-stabilising drugs, is rarer than it should be. Models of the period after the Big Bang explain how it, hydrogen and helium were synthesised in nuclear reactions, before the universe cooled enough for the stars and planets that we see today to come into being.

Getting to the heart of the matter: CERN’s hidden heritage

A nuclear physicist and an archaeologist at the University of York have joined forces to produce a unique appraisal of the cultural significance of one of the world's most important locations for scientific inquiry.
