What happens inside a dying star? A recent experiment at CERN's REX accelerator offers clues that could help astrophysicists to recalculate the ages of some of the largest explosions in the universe.
An object discovered by astrophysicists at the University of Toronto (U of T) nearly 500 light years away from the Sun may challenge traditional understandings about how planets and stars form.
An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity ...
(Phys.org) —For astrophysicists, the interplay of hydrogen—the most common molecule in the universe—and the vast clouds of dust that fill the voids of interstellar space has been an intractable puzzle of stellar evolution.
Could the famed "Big Bang" theory need a revision? A group of theoretical physicists suppose the birth of the universe could have happened after a four-dimensional star collapsed into a black hole and ejected debris.
The race is on to solve the mystery of dark energy, the unknown force that is causing the universe to expand faster and faster. It's one of the biggest open questions in cosmology, but now a handful of high-profile projects ...
(Phys.org) —Star clusters with properties not seen before have been discovered by an international team of astrophysicists, led by Swinburne University of Technology's Professor Duncan Forbes.
Enceladus, a white moon of Saturn with ice-spewing volcanoes, owes its strangeness to tides of gravitational forces exerted by its mother, a study in Nature said on Wednesday.
