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.

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.
