Saturn’s moon Enceladus could have ocean currents below subsurface, shows study
Buried beneath 20 kilometers of ice, the subsurface ocean of Enceladus—one of Saturn's moons—appears to be churning with currents akin to those on Earth.
The...
Scientists capture the magnetic fields at edge of this black hole
Black holes don't just take in matter. They also spit it out.
From their polar regions, they can launch massive jets of energetic plasma that...
How fast is the universe expanding?
Determining how rapidly the universe is expanding is key to understanding our cosmic fate, but along with more precise data comes a conundrum.
Estimates based...
