To detect dark matter, you need to build an ultra-sensitive detector and put it somewhere ultra-quiet. For one physics collaboration, that place is almost a mile under Lead, S.D.

The universe used to be filled with a hydrogen fog, before early stars and galaxies burned through the haze. Astronomers are studying galaxies that tell them about this period in the early universe.
A new survey catalogs Americans’ expectations about the future of space, from NASA to SpaceX. Two space policy experts describe how these results stack up against the current state of space affairs.
To find out what is beyond space, a good place to start would be to figure out where space – our universe – ends.
If an astronaut were to die on Mars, neither cremation nor burial would be good options.
The way particles interacted while the universe was forming seconds after the Big Bang could explain why the universe exists the way it does – a physicist explains matter-antimatter asymmetry.
Both Stephen Alexander’s elementary teachers and televised NASA missions throughout the ‘60s influenced his journey into science. He recounts NASA’s legacy, 65 years after the agency’s inception.
Three Indigenous studies scholars draw from colonial histories and explain why listening for alien life can have ethical ramifications.
Ready or not, sex in space will be happening within the decade.
While a return to the Moon will allow the U.S. to collaborate with other nations interested in space, this endeavor is also complicated by geopolitical tensions.
While UFO videos might seem compelling, they’re rarely backed up with evidence. A sociologist explains why claims of alien life gain traction through both social and mass media every few years.
Astronomers have detected the coldest star ever found to emit radio waves using the Australian SKA Pathfinder telescope.
Space telescopes are limited in size due to the difficulties and cost of getting into orbit. By revamping an old optical technology, researchers are working on a lightweight and thin telescope design.
If you haven’t seen Stanley Kubrick’s 1968 sci-fi classic, then it’s likely you will have seen other films influenced by it.
With a solar eclipse and several meteor showers coming up, an astronomy professor shares travel tips for viewing astronomical phenomena.
Astronomers have for the first time detected the background hum of gravitational waves likely caused by merging black holes.
The planet Halla looks like it should have been devoured by its host star, a red giant called Baekdu – but a secret in the star’s past may hold the answer to the planet’s present.
Advances in technology have allowed tourists to go to places and do things they couldn’t in the past. But in extreme environments, the consequences of failure are high.
President Erdoğan has been hoping his government’s science wins would spark a wave of patriotic support.
Upgrades to the hardware and software of the advanced observatory should allow astrophysicists to detect much fainter gravitational waves than before.
