Yes, the cartilage disks in your spine expand due to the lack of gravity, making you taller.
Roughly 5 billion years. (A closer approximation is 4.6 billion years)
Vredefort Ring in South Africa, 299km diameter! There is conjecture around the Chicxulub crater in Mexico being potentially bigger though.
Charged particles from the solar winds slowing down in our atmosphere.
The Drake equation, named after Frank Drake.
N = R* • fp • ne • fl • fi • fc • L
N = The number of civilizations in the Milky Way Galaxy whose electromagnetic emissions are detectable.
R* = The rate of formation of stars suitable for the development of intelligent life.
fp = The fraction of those stars with planetary systems.
ne = The number of planets, per solar system, with an environment suitable for life.
fl = The fraction of suitable planets on which life actually appears.
fi = The fraction of life bearing planets on which intelligent life emerges.
fc = The fraction of civilizations that develop a technology that releases detectable signs of their existence into space.
L = The length of time such civilizations release detectable signals into space.​​​​​
Yes! The entire solar system is orbiting the center of our galaxy plus the Sun itself rotates.
A term 'spaghettification' has been used here! The closer you are to a black hole, the faster you accelerate towards it. Basically your feet would be pulled faster toward the black hole than your head which means you would stretch and stretch until shredded!
Olympus Mons is the largest volcano in the solar system. Found on Mars, it is 3 times higher than Mt Everest. It can be this big due to lower gravity on Mars as well as the lack of plate tectonics.
The universe is about 13.8 billion years old.
The nearest star to earth, excluding the sun, is about 4.3 light years away. Its name is Alpha Centauri.
False. All matter pulls all other matter towards it, this pull is what we call ‘gravity.’ In space, this pull is just much weaker because you are further away from other matter.
No. The gas molecules in space - and yes there is gas - are too far apart for sound to properly travel.
Supernova. Each blast is the extremely bright, super-powerful explosion of a massive star as it dies.
Distance. How far light travels in 1 year! (9.46 trillion kilometres (9.46 x 1012 km))
False. Correct answer: Astronomer. An astrologer is a person who believes that you can get information about people’s lives from patterns in the stars. Lots of scientists have tried to study this, but have not found any evidence that it actually has any effect on our lives.
True. Mercury, Venus, Earth and Mars are terrestrial planets (also known as rocky planets). They are mostly made up of silicate rocks and metals. Jupiter and Saturn are known as gas giants, while Uranus and Neptune are ice giants.
At least 82 moons are known to orbit Saturn, of which 53 are officially named; this does not include the hundreds of moonlets in its rings.
Alpha Proxima Centauri. It’s about 4.2 lightyears away from us. If you travelled there in one of today’s rockets, it’d take you about 168,000 years to get there!
When the moon is full and at its closest point to the Earth.
True. Space debris (or space junk) orbiting the Earth can be travelling at up to 8km/s. That’s faster than a bullet!
True. US astronaut Scott Kelly shaved 13 milliseconds off his Earth age by spending 11 months aboard the International Space Station. He and his identical twin Mark (who is also an astronaut) have also taken part in studies to investigate the genetic effects of spaceflight.
Neither, they would both hit the ground at the same time. The difference is that there’s no atmosphere on the moon and so no air resistance. On Earth, the air resistance will slow the feather down more than it slows down the hammer. The earth's gravity pulls all objects down at the same rate(9.8 m/s 2), assuming there is no air resistance. They actually did this experiment with a hammer and a feather on the Moon in 1971 during the Apollo 15 mission.
False The moon appears larger on the horizon. It’s called the moon illusion and no one knows exactly why it is happening, but they think it’s to do with how our brains adjust the size of things that we’re seeing by comparing it with familiar objects in the foreground.
True It happened billions of years ago during a period called the Late Heavy Bombardment.
