100 Interesting Facts about Universe – Part 2

1Accretion Disks

The brightest object in the universe is called a Quasar, also known as a black hole that is consuming a star creating Accretion Discs.

2. If the Andromeda galaxy were bright enough to be seen by the naked eye, it would appear six times larger than a full moon.

3. The Andromeda galaxy is heading towards us at 250,000 miles per hour. We are expected to collide with it in 4 billion years.

4. Neutron stars can contain up to twice the mass of the sun. A sugar-cube-sized bit of material from a neutron star would weigh about 1 billion tons.

5. The Andromeda galaxy is larger than the moon in the sky, but it is usually too dim to see.

6Abd al-Rahman al-Sufi

A Persian astronomer named Abd al-Rahman al-Sufi discovered Andromeda Galaxy way back in 964 A.D.

7. The Andromeda galaxy is actually 8 times larger than the moon in the night sky but is hard to make out unless there's minimal light pollution.

8. It is thought that the Star of Bethlehem may have been a Supernova occurring in the nearby Andromeda Galaxy.

9. The distance to the Andromeda galaxy is less than 10 times its diameter.

10. Bananas produce Antimatter at the rate of one Positron every 75 minutes.

11Antimatter spaceship

10 Milligrams of Antimatter would be enough to fuel a mission to Mars in as little as 45 days, but producing that amount of Antimatter would cost roughly 250 million USD.

12. Russia has a vast diamond field containing "Trillions of Karats", enough to supply global markets for another 3000 years. The field was discovered in the 1970s underneath 35 million-year-old asteroid crater in Siberia.

13. Thunderstorms create antimatter.

14. Jupiter is a "Cosmic Vacuum Cleaner." Its gravitational influence causes comets and asteroids to collide with it. The rate of impacts on Jupiter is about 2000-8000X higher than the rate on Earth. Without Jupiter, the probability of asteroid impacts with the inner planets would be much greater.

15. The asteroid impact that killed the dinosaurs was powerful enough to send Earth rocks to Mars and even Europa. As a result, if we ever find life on those worlds it may actually have originated on our own planet.

16Asteroid worth

A single asteroid can contain $20 trillion worth of metals.

17. The asteroid that killed the dinosaurs also caused volcanoes to erupt everywhere, acid rain which burned flesh and vegetation, a sulfuric gas that blocked out sunlight for years, vaporized rocks as deep as the sea floor, and mega tsunamis up to 2 miles (3.22km) high.

18. NASA estimates that the value of minerals in the asteroid belt exceeds $600,000,000,000,000,000,000. Or nearly $100 billion per person alive.

19. Japan successfully landed an unmanned spacecraft on an asteroid, collected samples in 2005. The probe returned to earth in 2010.

20. A man named Gregory W. Nemitz claimed ownership of Asteroid 433 Eros, on which near Shoemaker landed in 2001. His company Orbital Development issued NASA a parking ticket for $20.

21Lasso

NASA plans to lasso an asteroid and drag it to the moon for astronauts to walk on.

22. Earth is being shadowed by a minor planet called 2010 TK7, a 300-meter diameter Trojan asteroid that orbits the sun in a spiral pattern every 365.3 days, 60° ahead of Earth's track through space. It has a gravitational force 1/20000 that of Earth and was only discovered in 2010.

23. In March 1989, an asteroid passed through the exact position where Earth was only six hours earlier.

24. The Richter Scale doesn't stop at 10.0 and that asteroid that killed the dinosaurs was equivalent in energy release to a 13.0 earthquake.

25. J002E3, originally thought to be an asteroid orbiting the Earth, is actually part of the Apollo 12 mission that returned to Earth orbit after 31 years of orbiting the Sun.
