Due to the Moon drifting away from Earth at a rate of about 1.5 inches per year, our planet's rotation is gradually slowing down. In about a billion years, a day could stretch to 28 hours
The Boomerang Nebula holds the record for the coldest known natural place, with a temperature of just -458 degrees Fahrenheit (-272 degrees Celsius), only one degree above absolute zero.
Venus takes about 243 Earth days to complete one rotation but orbits the Sun in just 225 Earth days, making a year on Venus shorter than a day.
A sugar-cube-sized amount of material from a neutron star would weigh about as much as all of humanity combined due to the extreme density of closely packed neutrons.
The universe is expanding at an accelerating rate due to dark energy, causing some galaxies to move away from us faster than the speed of light.
Estimates suggest there are more stars in the universe than grains of sand on all the beaches on Earth combined, with around 100 billion trillion stars.
When a star gets too close to a black hole, it can be torn apart by gravitational forces in a process called "spaghettification," before being consumed by the black hole.
