August 28, 2018 E.T., phone Earth? How neutron-star crashes could help aliens call us The first-ever observations of merging binary stars stunned the astronomy community last year, but not quite as much as the first-ever signal from extraterrestrial life might someday stun the world.
August 22, 2018 Physicists think they've spotted the ghosts of black holes from another universe We are not living in the first universe. There were other universes, in other eons, before ours, a group of physicists has said. Like ours, these universes were full of black holes. And we can detect traces of those long-dead black holes in the cosmic microwave background (CMB) — the radioactive remnant of our universe's violent birth.

August 14, 2018 The origins of the 'OMG particle' Right now, as you read this very text, your DNA is getting sliced up by tiny, invisible bullets. The damage-dealers are known as cosmic rays, even though they are absolutely not rays — but the name stuck from a historical misunderstanding. Instead, they're particles: electrons and protons, mostly, but occasionally heavier things like helium or even iron nuclei.
