For the first time, astronomers have observed the rapid dimming of a distant quasar and realized that the active black hole engine must have gone on an extreme diet.
A machine on Earth capable of recreating the conditions inside the sun's heart is helping scientists study how iron behaves at mind-boggling temperatures. The results of the experiment, so far, have defied expectations and just might help settle a long-standing solar puzzle.
Measuring the age of stars has been a notoriously difficult proposition, but now astronomers can pin down stellar chronology to a better precision than ever.
'Raise shields!' may be a familiar defensive order given in the Star Trek Universe, but according to space scientists in our Universe, Planet Earth has its own built-in invisible shield that buffers 'killer electrons' from orbital altitudes.
So-called strange stars, made of radically different stuff than ordinary matter, may finally be detectable.
As galaxies mature, they stop forming stars -- but why? Now astronomers are hot on the trail of finding the culprit. Continue reading →
An app called the Distributed Electronic Cosmic-Ray Observatory allows smartphone owners to detect high-energy particles.
If you thought the search for the Higgs boson — the elusive particle that endows matter with mass — was epic, spare a thought for the physicists who have been trying to find a way to discover another subatomic particle … Continue reading →
