Our coverage sheds light on the boundless darkness, the physical violence and the mysterious, awesome reaches of our universe. We ponder how it all began and about our place in the cosmos: Are we alone? Is there life on other planets? Will interplanetary travel save the human race? We also explore space through images, videos and illustration.
First gravitational wave detection of colliding neutron stars sent scientists racing to collect light from the event.
Anything that has mass and moves can give off gravitational waves, but for familiar items they are extremely tiny.
A 100-year-old theory helped open up a brand-new world of astronomy.
The Deep Underground Neutrino Experiment may address important physics questions and change the way we look at our planet.
