Space Facts – Top 20 of Rare and Amazing Facts

Rare Space Facts – Top 20

Space facts presented below are a selection of current facts of modern science that are simply mind-puzzling, and equally astonishing. Here at Science Facts, we are delighted to deliver our Top 20 list in no particular order – enjoy!


  1. The highest temperature in the universe that matter could exist at, equals to 142 decillion Centigrade (142,000,000,000,000,000,000,000,000,000,000 C). It’s called Planck Temperature, above which conventional physics break down.
  1. Quantum gas goes below Absolute Zero (-273.15 C) which was considered to be the coldest temperature ever possible.
  1. The farthest galaxy ever discovered to date is MACS0647-JD. It lies 13.3 billion light years away and was picked up by the Deep Space Hubble Space Telescope (HST).
  1. NASA believes that at least 21 exoplanets (one that orbits a star) discovered to date, could host alien life as they’re extremely similar to Earth.
  1. The farthest man-made object is Voyager 1 at about 12 billion miles away (it has messages for aliens on-board).
  1. Neutrino is the smallest ever recorded particle in the universe. It has the smallest cross section of all – 0,000,000,000,000,000,000,000,001 m (WIMPs are supposedly even smaller, but were never seen).
  1. The largest known structure in the universe is Hercules-Corona Borealis Great Wall at 10 billion light-years across (it’s a huge group of galaxies forming a giant sheet-like pattern).
  1. The biggest star discovered to date is VY Canis Majoris and 1 billion Earths could fit inside of it.
  1. Tachyons sub-atomic particles are reportedly the fastest moving things in the cosmos, though they are hypothetical and were never observed.
  1. The fastest-spinning neutron star ever found, spins near the center of the Milky Way at 716 turns around its own axis per second.
  1. Each Space Shuttle astronaut is allotted 3.8 pounds of food per day (including the one pound of packaging).
  1. A feather near a black hole would weight several billion tons due to the super-colossal gravitational pull.
  1. There are more stars in the universe than there are grains of sand on the Earth.
  1. The biggest active volcano on Mars is 3 times bigger than Everest, and if it erupted it would have been heard from nearly 25,000 miles away.
  1. The brightest ever recorded event in the cosmos was a super-luminous supernova explosion at 400 billion times brighter than the Sun, which was observed in June this year.
  1. The fastest speed ever achieved by NASA was Apollo 10 at 24,790 mph (approx. 32 x speed of sound, and 0.0037% of the speed of light – back in 1969).
  1. An area of the Sun’s surface equivalent to a nickel would shine with the brightness of about 1,500,000 candles.
  1. The universe is 68 percent dark energy and 27 percent dark matter, none of which has been observed by us.
  1. The average cost to launch a Space Shuttle is about $450 million per mission.
  1. SDSS-J010013 is the largest and brightest black hole ever found at 12 billion times bigger than the Sun.
