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!
- 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.
- Quantum gas goes below Absolute Zero (-273.15 C) which was considered to be the coldest temperature ever possible.
- 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).
- 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.
- The farthest man-made object is Voyager 1 at about 12 billion miles away (it has messages for aliens on-board).
- 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).
- 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).
- The biggest star discovered to date is VY Canis Majoris and 1 billion Earths could fit inside of it.
- Tachyons sub-atomic particles are reportedly the fastest moving things in the cosmos, though they are hypothetical and were never observed.
- The fastest-spinning neutron star ever found, spins near the center of the Milky Way at 716 turns around its own axis per second.
- Each Space Shuttle astronaut is allotted 3.8 pounds of food per day (including the one pound of packaging).
- A feather near a black hole would weight several billion tons due to the super-colossal gravitational pull.
- There are more stars in the universe than there are grains of sand on the Earth.
- 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.
- 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.
- 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).
- An area of the Sun’s surface equivalent to a nickel would shine with the brightness of about 1,500,000 candles.
- The universe is 68 percent dark energy and 27 percent dark matter, none of which has been observed by us.
- The average cost to launch a Space Shuttle is about $450 million per mission.
- SDSS-J010013 is the largest and brightest black hole ever found at 12 billion times bigger than the Sun.
