40 Awesome Facts About Observable Universe That You Love To Know(Space Facts)

40 Awesome Facts About Observable Universe That You Love To  Know (Interestingawesome.blogspot.com)

"For since the fabric of the universe is most perfect and the work of a most wise Creator, nothing at all takes place in the universe in which some rule of maximum or minimum does not appear."
Leonhard Eulers

The Universe is all about time, space and its contents. It includes planets, moons, minor planets, stars, galaxies,all the matters and energies. The observable universe is about 28 billion parsecs (91 billion light-years) in diameter. The size of the entire Universe is unknown, but there are many hypotheses about the composition and evolution of the Universe.

Universe is an extraordinary place. It is so vast and  it’s extremely difficult to know the full extent of its complexities. Humans can only scratch at the surface of its immensity, but whenever we do we pick up remarkable information, and images, which are awe inspiring and baffling in equal measure. Balls of burning gas; holes that trap light and everything else; stars made out of diamonds; these are but a few of the many things that make our universe a scary but wondrous place. In my previous post "Awesome Facts About Universe Part 1", I mentioned so many wonderful facts about universe. So from here, I am going to continue my previous post. Here are some more awesome facts about universe for your knowledge.

  1. The Moon has no atmosphere, which means there is no wind to erode the surface and no water to wash the footprints away. This means the footprints of the Apollo astronauts, along with spacecraft prints, roverprints and discarded material, will be there for millions of years.(Please note, The atmosphere of the Moon is a very scant presence of gases surrounding the Moon. For most practical purposes, the Moon is considered to be surrounded by vacuum.)
  2. Cold Welding is a incredible phenomenon used to describe the fact that whenever two pieces of metal in outerspace touch each other, they are more or less permanently stuck together. While welding usually requires heat. This doesn’t happen on Earth because of the air and water found between the pieces.
  3. Though it is impossible to smell space directly or through a spacesuit, astronauts report that upon returning from a spacewalk, their gear smells distinctively like seared steak, hot metal, and arc welding fumes. The source of this odor could be byproduct from dying stars, the traces of which can be found throughout the universe.
  4. Black holes are formed when some very large stars collapse and condense all of their mass into a very small area, known as the Schwarzschild radius. Earths Schwarzschild radius is just below nine mm (1/3 inch), and if it were to be compressed below that size, our planet would become a black hole. For a person to become a black hole, they would have to be compressed smaller than a proton.
  5. When analog television sets aren’t tuned to a channel correctly, it results in static and white noise. Around 1% of that is radiation left over from the Big Bang, better known as the Cosmic Microwave Background (CMB) .This interference between overlapping signals actually allowed Arno Penzias and Robert Wilson to discover the CMB in 1965.
  6. Glowing nebulae are named so because they give off a dim, red light, as the hydrogen gas in them is heated by radiation from the nearby stars.
  7. Twice during Mercurys orbit, it gets so close to the Sun and speeds so much that the Sun seems to go backwards in the sky.
  8. A comets tail is made as it nears the Sun and begins to melt. A vast plume of gas millions of kilometers across is blown out behind by the solar wind. The tail is what you see, shining as the sunlight catches it.
  9. Jupiter spins right round in less than 10 hours which means that the planets surface is moving at nearly 50,000 km/hr.
  10. To save fuel on journeys to distant planets, space probes may use a nearby planet’s gravity to catapult them on their way. This is called slingshot.
  11. Three moons have yet been found to have their own moons: Saturn’s moon Titan, Jupiter’s  Leo, and Neptune’s Triton.
  12. The largest moon in the Solar System is the Jupiter’s moon Ganymede.
  13. Winds ten times stronger than a hurricane on Earth swirl around Saturns equator reaching up to 1100 km/h and they never let up: even for a moment.
  14. In summer in Uranus, the sun does not set for 20 years. In winter, darkness lasts for 20 years. In autumn, the sun rises and sets every 9 hours.
  15. Uranuss moon Miranda is the weirdest moon of all. It seems to have been blasted apart, and then put together again.
  16. The asteroid belt between mars and Jupiter would turn into a planet if Jupiter did not exist since Jupiter is a large planet it has a high gravitational pull so the pull it has will never let it become a planet.
  17. Ceres is the biggest asteroid in the Solar System 940 km across, and 0.0002% the size of the earth.
  18. Neptune’s mood Triton is the coldest place in the Solar System, with surface temperatures of 236°C.
  19. The heart of a star reaches 16 million °C. A grain of sand this hot would kill someone 150 km away.
  20. The sun gets hot because it is so big that the pressure in its core is so tremendous enough to force the nuclei of hydrogen atoms to fuse to make helium atoms. This nuclear reaction is like a gigantic atom bomb and it releases huge amounts of heat.
  21. Quasars are the most distant known objects in the Universe. Even the nearest is billions of light years away.
  22. The brightest stars in the night sky are not actually stars, but the planets Jupiter, Venus, Mars and Mercury.
  23. A tablespoon of neutron star would weigh about ten billion tones.
  24. The earth actually takes 365.24219 days to orbit the Sun, which is called one Solar Year. To compensate for the missing 0.242 days, the western calendar adds an extra day in February every fourth (leap) year, but misses out three leap years every four centuries.
  25. The future of the Universe may depend on how much dark matter there is. If there is too much, its gravity will eventually stop the Universes expansion and make it shrink again.
  26. A person on the equator is rotating around the Earth at about 1,660 kilometers per hour. A person at the north or south pole actually has a rotational speed of zero, and is effectively turning on the spot. Somewhere in between, a persons rotational speed decreases as they move from the equator towards the pole.
  27. The Earth circles around the Sun at about 107,000 kilometers per hour. Our Solar System is rotating around the Milky Way galaxy at about 700,000 kilometers per hour.
  28. The next nearest star to us (other than the Sun) is Proxima Centauri, in the Alpha Centauri star system, which is about 40 trillion, miles away or,4.24 light years .
  29. About 3,000 stars are visible to the unaided eye on a clear moonless night. About 100,000 stars can be seen using a small telescope.
  30. The Voyager 1 spacecraft is the most distant human-made object from Earth and it also captured the most distant photograph of Earth which launched on 1977.
  31. Each year scientists have determined that the moon moves about 3.8 cm further from the Earth. As a result, Earths spin has slowed by about .002 seconds every day over the course of the last century.
  32. The moons gravity is 17% of the Earths so astronauts in space suits can jump 4 m high on the moon.
  33. If you fell into a black hole, you would stretch like spaghetti.
  34. True binary stars are two stars held together by one anothers gravity, which spend their lives whirling around together like a pair of dancers.
  35. Halley predicted that a comet he had discovered would return in 1758, 16 years after his death, and it really did. It was the first time a comets arrival had been predicted, and the comet was named after him as Halleys Comet.
  36. Voyager 2 will beam back data until 2020 as it travels beyond the edges of the Solar System.
  37. The first living creature in space was the dog Laika on board Sputnik 2 in 1957. Sadly, she died when the spacecrafts oxygen supply ran out.
  38. The most distant galaxies (quasars) have red shifts so big that they must be moving away from us at speeds approaching the speed of light.
  39. The Hiroshima bombs released 84 trillion joules of energy. A supernova releases 125,000 trillion trillion times as such.
  40. Absolute zero , the temperature at which thermal energy is theoretically zero and which is therefore generally considered the coldest possible temperature, is -273.15°C Celsius The cosmic microwave background radiation which uniformly permeates all of space has a temperature of 2.725°K, or around -270°C.
