An overlooked but powerful driver of cloud formation could accelerate the loss of polar sea ice.
Growing Inventory of Black Holes Offers a Radical Probe of the Cosmos
One black hole is nice, but astrophysicists can do a lot more science with 50 of them.
In Violation of Einstein, Black Holes Might Have ‘Hair’
A new study shows that extreme black holes could break the famous “no-hair” theorem, and in a way that we could detect.
Rumbles on Mars Raise Hopes of Underground Magma Flows
