Top 10 of things in space

One of the emptiest things in universe, is the universe. Without it, there’s nothing. So there is cool stuff to find in universe. Here’s our non-quantative list:

1. Voyager 1 & 2 – in 1977 NASA launched two spacecrafts into space. At the moment Voyager 1 is about 17.5 billion kilometers away from us exploring the outer part of our solar system. A command from earth takes 13 hours to reach the spacecraft.
2. Black Holes – objects with a gravitational attraction that is so strong that the escape velocity equals the speed of light, preventing light from leaving its ‘ surface’.
3. Quasars – extreme objects. Quasars are extremely luminous, extremely distant galaxies and very powerful radio sources
4. Light – radiant energy, travelling at the speed of light or 299,792.5 kilometers per second.
5. Supernova – the titanic explosion of a star. From the star’s point of view a quick and glorious death. During the explosion the star uses more energy than it has used during its lifetime, leading to an extreme luminosity.
6. Pluto – a lonely planet chilling at the edge of our solar system. Pluto’s mass is about 0,002 times the Earth’s.
7. The Great Attractor – an assemblage of superclusters, at about 260 million light years away from us. The Great Attractor contains 10.000 galaxies like the Milky Way.
8. Supercluster – a cluster of galaxy clusters spanning over 100 million light years
9. Dark Matter – material that accounts for discrepancy between the mass of a galaxy according to Kepler’s third law and the mass observable in the form of stars and gas. It should be there…
10. The Sun – our star
