The prospect of picking my own blog topic this week out of any and all astronomical topics was just TOO daunting for an indecisive person like me. So, I decided to just talk about a bunch of really super incredible amazing things all in the same post. The following are some seriously AWESOME astronomical facts:
- Only one two-billionth of the sun’s energy output is actually sent to the Earth.
- When an object falls into a black hole, scientists call it “spaghettification” because of the way black holes stretch the objects they absorb.
- If you could find a body of water big enough to put Saturn in it, Saturn would float.
- Saturn’s moon Titan, Jupiter’s moon Lo, Neptune’s moon Triton are all so massive that they’ve pulled their own moons into orbit.
- The core of a star can reach temperatures of 16 million degrees Celsius. If a single grain of sand was this hot, it would be able to kill a human being from 150 kilometers away.
- Neutron stars are so incredibly dense that a single tablespoon of their matter would weigh approximately 10 billion tons.
- 96% of the universe cannot be seen because it does not emit or reflect light.
- Technically, “space” begins at the Karman Line, which is only 100 km above the surface of Earth. Thus, a car driving into the sky could be in space in less than an hour.
- Since there is no wind or atmosphere on the Moon, footprints there will last pretty much forever…or until our Sun explodes or s meteor collides with it or something else disastrous like that.
- Scientists have discovered a star that is so cold and compact it has crystallized into a solid diamond.
Pretty sweet, right?
