The only other pulsar known to have ever approached Vela’s energy level was the Crab Pulsar, situated over 6,000 light-years from Earth — and even that constellation maxed out at just 1 ...

NASA's ISS-mounted X-ray telescope NICER has weighed and measured the closest pulsar to Earth. The neutron star PSR J0437 spins 174 times a second and has a mass of 1.4 suns.

For example, we could theoretically use Earth as a flywheel system, storing the kinetic energy from its spin to apply to our energy needs. "If you used the spinning momentum of the planet to meet ...

The Earth's spin is really starting to pick up speed. As CBS News reports , June 29 was the fastest day in recorded history, clocking in at 1.59 milliseconds shorter than the average 24 hours we ...

That sloshing around can influence the speed of the Earth’s spin, ABC reported. Some scientists think this could be the beginning of a new period of shorter days, Interesting Engineering reported.

A constellation of satellites orbiting 250 miles above Earth’s surface shows how solar and wind have taken off in recent years: Here’s what renewable energy sites looked like eight years ago ...
