Prepare to be surprised as we journey into the region of the unknown, unraveling one startling space truth after another. Buckle up and get ready to see the universe as you've never seen it before.
Facts about space
1) One million Earths may fit within the Sun — and the Sun is considered an average-size star.
2) For years it was believed that Earth was the sole planet in our solar system having liquid water. More recently, NASA provided its clearest evidence yet that there is intermittent running water on Mars, too!
3) Comets are remnants from the birth of our solar system around 4.5 billion years ago — they consist of sand, ice and carbon dioxide.
4) Jupiter, Saturn, Uranus, and Neptune don't have a solid surface, thus you couldn't walk on them!
5) Space is entirely silent.
6) The only two planets in our solar system without moons are Mercury and Venus.
7) If a star approaches too close to a black hole, it can be split apart.
8) Space is a pretty frigid environment at –270.45 Celsius!
9) An asteroid around the size of a car hits Earth’s atmosphere roughly once a year — but it burns up before it reaches us. Phew!
10) The highest peak known to man is on an asteroid called Vesta. Measuring a massive 22km in height, it is three times as tall as Mount Everest!
11) More stars exist than there are sand grains on all the beaches on Earth.That’s at least a billion trillion!
12) The sunset on Mars appears blue.
13) Venus is the hottest planet in our solar system.
14) It has been around for 4.57 billion years.
15) Enceladus, one of Saturn’s smaller moons, reflects 90% of the Sun’s light.
16) The highest peak discovered is the Olympus Mons, which is located on Mars.
17) The "Pillars of Creation" are iconic formations in the Eagle Nebula imaged by the Hubble Space Telescope.
18) The Great Wall of China is not the only man-made object visible from space; motorways, airports, and cities are also visible.
19) The Kármán line, positioned at an altitude of about 62 miles (100 kilometers) above sea level, is generally regarded the limit of space.
20) The word "planet" derives from the Greek word "planetes," which meaning "wanderer."
21) Ganymede, a moon that revolves around Jupiter, is the biggest moon in the solar system.
22) Space is not as chilly as you might imagine; the lack of air means there is no way to transmit heat, so items in space can grow incredibly hot when exposed to sunlight.
23) Hydrogen and helium are two of the most prevalent elements in the universe.
24) A cosmic occurrence known as a "black hole collision" can cause ripples in spacetime called gravitational waves.
25) The Great Barrier Reef in Australia is the largest living structure on Earth and can be viewed from space.
26) Space telescopes like Hubble have produced crucial discoveries concerning the expansion rate of the Universe.
27) The idea of "space junk" refers to defunct satellites, spent rocket stages, and other garbage in orbit around Earth.
28) The Kuiper Belt is a region of the solar system beyond Neptune containing many ice objects and dwarf planets.
29) A day on Venus is longer than its year; it takes Venus 243 Earth days to complete one spin.
30) The phrase "light pollution" indicates the excessive artificial light that obscures our view of the night sky.
31) The concept of a "pulsar" refers to a fast spinning neutron star that generates beams of radiation.
32) In 1990, the Space Shuttle Discovery carried the Hubble Space Telescope into orbit.
33) Alan Shepard, who travelled to space in 1961 on the Freedom 7 spacecraft, became the first American astronaut.
34) The speed of sound in space is zero since there is no medium to transfer sound waves.
35) The Universe is expanding, and galaxies are moving apart from each other.
36) The Moon has a "dark side" that is not always under darkness but is never seen from Earth due to synchronous revolution.
37) Space organisations employ sophisticated telescopes and observatories to locate and study exoplanets in quest of habitable conditions.
38) The concept of "space weather" covers occurrences like solar flares and geomagnetic storms.
39) The largest asteroid in the asteroid belt, Ceres, was classed as a dwarf planet by the International Astronomical Union (IAU) in 2006.
40) A spacewalk, also known as an EVA (Extravehicular Activity), is when astronauts exit their spacecraft to work outdoors in space.
41) The "Mars rovers," including Spirit, Opportunity, Curiosity, and Perseverance, have explored the Martian surface.
42) The concept of "microgravity" refers to the circumstance in which objects experience a decreased gravitational force in orbit.
43) The concept of "time dilation" suggests that time passes differently for things in motion compared to each other.
44) The largest moon in our solar system, Ganymede, is even larger than the planet Mercury.
45) The largest volcano in the solar system, Olympus Mons on Mars, is around 370 miles (600 kilometers) in circumference.
46) The term "asteroid" comes from the Greek word "asteroeides," which meaning "star-like."
48)The Great Red Spot on Jupiter is a gigantic storm that has been seen for over 350 years.

FAQS
What is space?
Space, also referred to as outer space, is the immense expanse outside Earth's atmosphere that contains stars, planets, galaxies, and other astronomical objects.
How large is the Universe?
The observable Universe is estimated to be around 93 billion light-years in diameter, although the total Universe could be far larger and is still a topic of scientific inquiry.
What differentiates a planet from a star?
Stars are celestial objects that generate their own light by nuclear fusion, while planets do not make their own light but instead reflect the light of surrounding stars, like our Sun.
How do black holes form? What are they?
A black hole is a place in space where gravity is so powerful that nothing, not even light, can escape. They originate when enormous stars collapse under their own gravity.
Can humanity survive in space?
Humans can exist in space with the correct technology, such as spacesuits and spacecraft that provide life support systems, including oxygen and temperature control.
Is there life beyond Earth?
While scientists have not yet uncovered definitive proof of extraterrestrial life, the quest for habitable habitats and hints of life on other planets and moons is ongoing.
What is the objective of space exploration?
Space exploration serves several aims, including scientific inquiry, technological breakthroughs, Earth observation, and the potential for future human colonization of other celestial bodies.
How can we calculate how far away stars and galaxies are?
Astronomers utilise methods such as parallax for close stars and the redshift of light for distant galaxies to estimate their distances in space.
What is the James Webb Space Telescope, and why is it important?
The James Webb Space Telescope (JWST) is a powerful space observatory poised to explore the Universe in infrared wavelengths. It intends to solve questions regarding the early Universe, exoplanets, and more.
What is the fate of our Sun?
In around 5 billion years, our Sun will exhaust its nuclear fuel, develop into a red giant, and eventually shed its outer layers, becoming a white dwarf. This step will mark the conclusion of its life cycle.
