1. Exoplanet Covered in Burning Ice
Astronomers believe Gliese 436 b an exoplanet placed about 33 light-years away in the constellation Leo, embodies exotic states of water that causes its surface to be covered in burning ice. Pressure forces the ice to stay solid, however, the surface temperature of 570° F (300° C) heats the water up, and it come off as steam.
2. Eau de Cosmos
Astronauts report, after returning from a spacewalk, their gear smells distinctively like seared steak, hot metal, and arc welding fumes. The odor is likely caused by a byproduct of dying stars, the traces of which can be found throughout the universe.
3. Intergalactic Kegger
Nearly 10,000 light-years away in the constellation Aquila, there’s a cloud of alcohol whose diameter is 1,000 times larger than our solar system. The ethyl alcohol present in the cloud could serve up to 400 septillion (400, followed by 24 additional zeros) drinks.
4. Closest Neighbor
The Andromeda galaxy our close galactic neighbor, is 140,000 light-years across, still it isn’t bright enough to be seen in the night sky by our eyes.
5. Earth Under Pressure
When large stars collapse and condense all of their mass into a very small area, that phenomenon is called Schwarzschild radius. Planet Earth’s Schwarzschild radius is a little below nine mm (1/3 inch). If it were to be compressed below that size, it would turn into a black hole.
6. Stellar Nursery
The birth and death of stars is a process which happens fairly frequently. By using observed star formation and supernova events within the Milky Way, astronomers have found out that 275 million stars are born and die throughout the observable universe each day.
7. Galactic Year
Earth takes 24 hours to rotate on its axis to make a day, and 365 days to orbit around the sun for a year. Our solar system takes around 230 million years to finish a single orbit around the Milky Way. The last time it was in its current position, the earliest dinosaurs had just appeared.
8. Macerated Milky Way
The smell of our solar system is like hot metal and seared steak, however, the middle of Milky Way, smells like raspberries and tastes like rum, report the Max Plank Institute. They found that ethyl formate, a key chemical component for both raspberries and rum, can be readily found at the center of our galaxy.
9. Time Flies
Every century, Earth’s rotation slows down by about 1.4 milliseconds. At the time of dinosaurs, a day lasted about 23 hours. NASA reports that Earth’s rotation was exactly 24 hours in 1820, but is now off by 2.5 milliseconds.
10. Habitable Zones
Milky Way has 200-400 billion stars and around 100 billion planets. Astronomers believe 22 % of these stars have planets the size of Earth in their habitable zone, where water can exist as a liquid. Means, up to 8.8 billion planets within the galaxy can support life.
11. White Noise
Static and white noise is produced when analog television sets aren’t tuned to a channel correctly. Almost 1% of that is radiation left over from the Big Bang, more precisely Cosmic Microwave Background (CMB). This interference between overlapping signals in fact allowed Arno Penzias and Robert Wilson to discover the CMB in 1965.
12. Quasar Query
Quasars occur when gas swirls around a black hole real fast, and friction causes it to heat up, emitting light. Astronomers have found a team of 73 quasars which are around 6.5 times larger than the standard quasar group; this structure is over four billion light-years wide, and in fact cannot be explained by the Theory of General Relativity.
13. Spin Cycle
Pulsars are magnetized neutron stars that spin really fast and throw out a beam of radiation. PSR J1748-2446ad, located around 18,000 light-years away in the constellation Sagittarius, spins an astonishing 716 times per second. Or nearly a quarter of the speed of light.
