40 Incredible Space Facts: Every Astronomer Should Know


 Here are some incredible astronomical space facts for you 

stellar black hole
There are tens of thousands of black holes at the center of our home Milky Way galaxy hundreds of them are paired with a star and nearly 10,000 are isolated one's black holes are impossible to spot because light can't escape from them, astronomers can only track them down with album x-rays or by estimating their gravitational pull.
  • It rains molten glass on some planets 
  • Some planets have moons with their own rings 
  • Some planets have active volcanoes that spit ice like pluto

Scientists now know what space sounds like enthralled then let's discover some more astounding space facts

Venus spins at its own unhurried pace a full rotation takes 243 Earth days and it takes the planet a bit less than 225 Earth days to go all the way around the Sun. It means a day on Venus is longer than a year. 

You can see solar eclipses because even though the moon is 400 times smaller than the Sun it's also 400 times closer to earth so it's perfectly capable of obscuring the star but in 50 million years I won't be around, then the moon won't be able to block the Sun completely because of the satellites changing orbit.

The highest mountain in the solar system is Olympus Mons on Mars it's three times as high as Mount Everest the Earth's highest mountain above sea level if you were standing on top of Olympus Mons you wouldn't understand you were standing on a mountain its slopes would be hidden by the planet's curvature. here's topography

A full NASA space suit costs an unbelievable twelve million dollars yeah I can believe that 70% of this hefty sum is for the control module and backpack.

Astronomers have found a massive reservoir of water in space the largest ever detected too bad it's also the farthest 12 billion light-years away from us the water vapor cloud hole 140 trillion times as much water as all the Earth's oceans combined.

Utter space isn't a perfect vacuum it contains not only stars and planets but also clouds of interstellar dust space plasma and cosmic rays those are atom fragments dashing from the outskirts of the solar system.

One phenomenon people should be worried about while exploring space is cold welding if two pieces of the same kind of metal touch in space they bond and get permanently stuck together it doesn't happen on earth since water and air keep pieces separate. 

Astronauts onboard the International Space Station don't use their feet to walk they float around so in orbit the skin on their feet becomes very soft and starts to peel off that's why they have to take their socks off very carefully otherwise skin cells will break free and float around in the almost weightless environment.

Earthquakes on the moon or more correctly moonquakes aren't something from science fiction they don't occur as often as on our planet and when they do it happens closer to the center of the satellite scientists think moon quakes might be caused by the gravity of Earth and the Sun. 

One of the moons of Saturn Rhea might have a ring system consisting of three narrow bands if astronomers managed to confirm it it'll be the first time people discovered rings around a moon a that's nothing I've had rings around my collar for years. 

Normal visible matter for example planets and stars makes up just 5% of the universe the rest consists of invisible dark energy that's 68% and dark matter about 27% add it up and there's 95% of space we know nothing about in its darkest areas.

Space is freezing cold - 454 degrees Fahrenheit but try orbiting Earth and the sunlight and you'll understand how scorching 250 degrees feel that's one of the reasons astronauts space suits are white this color is the best reflect the heat from the Sun. 

There are six Mars exploration missions on or around the Red Planet at the moment does that mean that Mars is inhabited by robots.

The little green men aren't saying if the Sun was the size of a front door our planet would be the size of a nickel. In other words the Sun could fit more than 1 million Earth's.

Moon rocks have a super slow erosion rate of about 0.04 inches for every 1 million years that's why the Apollo astronauts footprints left on the moon are likely to stay there for 10 to 100 million years.
Jupiter's moon Io is four-and-a-half billion years old almost as old as the planet itself, it's one of the very few bodies in the solar system with active volcanoes and these volcanoes are powerful enough to produce spectacular views that are later captured by Earth's telescopes.

A neutron star gets born after a supernova collapses after birth it rotates extremely fast about 60 times per second but this rate can sometimes grow up to 600 times per second.

Space isn't supposed to be black there are stars everywhere shouldn't they light everything up around you don't see stars wherever you look because some of them haven't existed long enough for their light to reach earth.

Another one of Saturn's moons has unique two-tone coloring. 

The difference between the satellites to hemispheres is impressive, one of them is light and the other is eerily dark, scientists haven't figured out this mystery yet. 

All of the planets of the solar system would fit between Earth and the moon with some space left yes there's lots of space

In space Saturn isn't the only planet that has rings gas giants Uranus, Neptune, and Jupiter have rings of their own but they are thin and almost impossible to see. 

NASA can convert plasma waves radio waves and magnetic fields into audio tracks and listen to what's happening in space they record all kinds of intriguing sounds from beeps - ambulance-like Howl's at the same time-space itself is an eerily silent place there are some sound waves and vibrations but people can't perceive them. 

Chariklo is a tiny celestial body orbiting the Sun between Saturn and Uranus in the outer solar system just 157 miles across it's not a planet but it has two rings of its own and that's not one of them 

One of the things Jupiter's famous for is the Great Red Spot a giant spinning storm this phenomenon used to be so gigantic that it could fit two or even three Earth's but the spot is shrinking right now it wouldn't fit more than one earth.

Astronomers have found out the real hue of a planet orbiting another star for the first time, HD 189 733 beam has a beautiful azure color the reason might be molten glass rain falling down on the planet it scatters blue light in the atmosphere the planet might look like Earth from a distance but it's a gas giant orbiting very close to its star the temperature on the planet rises higher than 1800 degrees Fahrenheit

The only asteroid belt in the solar system astronomers know about is between Mars and Jupiter there are thousands of asteroids in this area their irregularly shaped solid objects of different sizes but all of them are way smaller than a planet.

The ocean on Jupiter is larger than any other in the solar system but unlike Earth's oceans it's made not of water but of metallic hydrogen the ocean's depth is a mind-blowing 60 miles (100 kilometers Thick) 10 times the depth of Earth's oceans. 

Scientists have analyzed the chemical content of some meteorites found in the Sahara Desert Antarctica and other places some of the rocks turned out to have Martian origin others arrived from the moon or the asteroid belt between Mars and Jupiter.

Earth gets more energy from the Sun in one hour than people spend in one year during the past 15 years we've started using 20% more solar energy it might seem like a big deal but it's just 0.7% of the amount of energy humans use every year. 

Venus is infamous for its powerful winds at the cloud tops they blow 50 times faster than the planet rotates these fierce winds never stop and can get even stronger with time. 

The largest canyon in the solar system Valles Marineris on Mars is more than ten times larger than the Earth's Grand Canyon some astronomers believe that the canyon appeared billions of years ago when the planet was cooling down. 

Cryovolcanoes on Pluto sometimes informally called ice volcanoes to spit ice or rather a melted mixture of water ice and frozen ammonia nitrogen and methane 

The Milky Way galaxy and the Andromeda galaxy are going to meet in three-point seven five billion years they're moving towards each other at breakneck speed when the two galaxies collide they'll form a huge elliptical galaxy
