00:00Think you know everything about space and science?
00:03Well, get ready to be amazed.
00:06From planets made of diamond to stars heavier than mountains.
00:10Here are 20 mind-blowing facts that sound fake, but are 100% true.
00:15Let's begin.
00:17Fact number one.
00:18Did you know?
00:19A day on Venus is actually longer than its entire year.
00:23It takes 243 Earth days just to spin once.
00:27Fact number two.
00:29Jupiter's great red spot is more than a storm.
00:32It's a storm that's been raging for over 300 years.
00:35Fact number three.
00:36Saturn is so light it could float on water.
00:39That is, if you had a bathtub big enough.
00:42Fact number four.
00:44Neptune has the fastest winds in the solar system, blowing at more than 1,200 miles per hour.
00:51Fact number five.
00:52The moon is slowly moving away from Earth, about 1.5 inches farther every year.
00:57Fact number six.
00:59There are more stars in the universe than grains of sand on all the beaches of Earth.
01:03Just imagine that scale.
01:06Fact number seven.
01:07Light from the sun takes 8 minutes and 20 seconds to reach Earth.
01:11So you're always seeing the sun in the past.
01:14Fact number eight.
01:15One tiny teaspoon of a neutron star would weigh more than 6 billion tons.
01:20Fact number nine.
01:21The Milky Way is headed straight for a galactic collision, with the Andromeda galaxy, in about 4.5 billion years.
01:29Fact number ten.
01:30Over 1.3 million Earths could fit inside the sun.
01:34That's how massive it really is.
01:36Fact number eleven.
01:37Time moves slower and stronger gravity.
01:40That means time ticks faster on a mountain than it does at sea level.
01:43Fact number twelve.
01:45Black holes bend space and time so much.
01:48From the outside, time almost seems frozen.
01:51Fact number thirteen.
01:53Absolute zero is the coldest temperature possible, where atoms completely stop moving.
01:57Fact number fourteen.
02:01There's a planet called 55 Cancri e.
02:03And it might be made almost entirely of diamonds.
02:07Fact number fifteen.
02:08The observable universe is about 93 billion light years wide.
02:13And it's still expanding every moment.
02:15Fact number sixteen.
02:17Astronauts grow taller in space, up to 2 inches more thanks to zero gravity.
02:22Fact number seventeen.
02:24You can't burp in space.
02:25Without gravity, gas and liquid won't separate inside your stomach.
02:30Fact number eighteen.
02:32Each astronaut suit costs around 12 million dollars.
02:36Yes, for just one suit.
02:38Fact number nineteen.
02:39If you were exposed to space without a suit, you wouldn't explode, but you would freeze and
02:44suffocate within seconds.
02:46Fact number twenty.
02:47Believe it or not, space has a smell.
02:49Astronauts say it smells like burnt steak, or welding fumes.
02:53So next time you look up at the night sky, just remember, the universe is even weirder and
02:59more wonderful than you ever imagined.
03:01Last time you look up at the night sky, the universe is even more wonderful than you ever imagined.
03:10Congratulations!
