🌎 Without the atmosphere, we would see the Sun as white. We perceive the Sun as yellowish or orange-red, depending on the time of the day and atmospheric conditions. But if you would remove the atmosphere, which scatters the light, the Sun would be seen as white. 😳

🤔 Moon has moonquakes, stars have starquakes
Events like earthquakes aren’t unique to our planet. But you can’t exactly call them earthquakes if they happen anywhere else than on Earth. Quakes on other planets have their own name. A quake on Venus is a venusquake. 😅

🌎 A planet can turn into a star
There are a couple of theories about how this could happen, one being that it is possible for a planet with a similar constitution as Jupiter, but with far greater mass, could support a fusion chain reaction if enough energy could be delivered to ignite it. 🌠

💫 Retrograde orbits of planets in our Solar System are an optical illusion. Retrograde motion is when an object moves or rotates in the opposite direction than its primary body – the Sun in our Solar System. 🤯

🌎 The closer the planet is to the Sun, the faster it moves. When a planet is closer to the Sun, the Sun’s gravitational pull is stronger, so the planet moves faster. This is described by the second Kepler’s law of planetary motion. 🤔

🌎 Earth sometimes has more than one moon
Kamoʻoalewa, an asteroid, is one of the most stable quasi satellites. It orbits the Sun but appears to be (currently) orbiting the Earth as well. It will leave orbit at one time (300 years or so). 😱

CERN’s Large Hadron Collider, Geneva, Switzerland, announced that they had achieved temperatures of over 5 trillion kelvins in 2012. The temperature of the Sun’s core is “only” 15 million kelvins. 😱

😨 As far as human hearing goes, space is silent
Everything makes noises, but sound can’t travel through space, so this is why we perceive space as being silent. 🌌

😳 The Big Bang Theory is the most accepted one but not the only theory of how the universe started.

3 Other theories that exist nowadays:
The eternal universe – a universe with no start, always being more or less as it is today

Steady-state – the universe is constantly expanding with new matter self appearing

The black hole theory – our universe was created from a black hole in another universe, meaning we live outside of its event horizon, and another (and another, and another) universe exists outside the black hole we are in. 😱

😱 You can watch the Big Bang, kind of grab an old analog TV, turn it on and watch the static noise. The static noise you see (the specks of white, gray, and black) is caused by random radio waves your TV picks up, both from artificial and natural sources, including radio waves from space. 🌌

😳 There is matter in the vacuum in space
A vacuum is defined as a space entirely devoid of matter. A perfect vacuum isn’t possible, as some types of particles will always be present.

Outer space is the closest to a perfect vacuum; however, you would still find a couple of hydrogen atoms per cubic meter of space. 🌌
