Study suggests black hole jets get their power from spin
(Phys.org) —A team of space scientists working in Italy has found more evidence that suggests the energy needed to emit jets from supermassive black holes comes from the spin of the black hole itself. In their paper published ...
New findings could help keep satellites and space debris from colliding
Half a million objects, including debris, satellites, and the International Space Station, orbit the planet in the thermosphere, the largest layer of Earth's atmosphere. To predict the orbits—and potential collisions—of ...
