Scientists have found a gigantic quasar 500 trillion times brighter than the Sun, fueled by the fastest-growing black hole known to exist.

Though the ERS-2 satellite is huge as far as space debris goes, it is expected to safely fall to the Earth without causing any harm or damage.

Washington announced Tuesday they had discovered new intelligence related to Russian nuclear capabilities and attempts to develop a space-based weapon.

It is unclear why Russia would need to use nuclear weapons to destroy a satellite. The New York Times said the United States cannot counter such a weapon.

If successful, the flight would represent the first controlled descent to the lunar surface by a US spacecraft since the final Apollo crewed moon mission in 1972, and the first by a private company.

The new capabilities, related to Russian attempts to develop a space-based weapon, do not pose an urgent threat to the United States, the source said.

Getting in the Super Bowl spirit? Sagittarius A*, the supermassive black hole at the heart of our galaxy, spins so fast that it makes spacetime around it shaped like a football.

Mimas is the seventh-largest moon of Saturn, which all told has well over 100 moons ranging from Titan - larger than the planet Mercury - to some only the size of a city block.

Scientists using NASA's James Webb Space Telescope found that black holes actually created stars and galaxies in the early universe, in a study that rewrites our understanding of the universe.

Asteroid era? Don't worry, the asteroid measured in terms of the "Shake it Off" sensation won't hit the Earth. It's not like "Everything Has Changed."
