The weird stuff in outer space

142. Quasars are the most energetic sources, and the most luminous objects in the universe. They can be 100 times brighter than a whole galaxy. Their name is an abbreviation of the term “Quasi-Stellar Radio Sources”.


143. Solar flares can be very dangerous, as they produce streams of charged particles that can damage our satellites, and pose risks to astronauts’ health. This radiation hazard is one of the biggest concerns for all manned missions that might be planned in the future.


144. The great attractor is a mysterious gravitational anomaly we discovered 250 million light years away. While we are uncertain what it is, we assume that it is probably a large collection of galaxies, or a galactic supercluster, that pulls towards it everything in its neighborhood.


145. Neutrinos are a special sort of elementary particle. These particles are electrically neutral and have virtually no mass. Because they don’t interact with normal matter, they can go through planets and whole stars without slowing down at all. It is incredibly difficult to detect them, and we use huge pools of water infused with cadmium chloride to spot them.


146. Higgs Boson is a theoretical particle that has no spin, no electric charge, but has mass. It is kind of the opposite of the neutrino. While we still can’t claim that we detected the Higgs Boson, scientists are pretty certain that they managed to detect one in the Large Hadron Collider in 2013.


147. There are four fundemantal forces in the universe: gravitational, electromagnetic, strong nuclear, and weak nuclear.


148. Time dilation is an effect that appears when something is traveling near the speed of light. If an astronaut was to launch from Earth and travel at a near-speed of light to our closest neighbor, Proxima Centauri it would take him 4.5 years. However, while years would pass on Earth, the astronaut would feel like he spent months, maybe even days on his journey.


149. The oh-my-god particle is the fastest particle we ever recorded. It’s a proton, one of the two particles that make atomic nucleus, which was moving at 99.99999999999999999999951% speed of light. This single particle with a mass of an electron has the equivalent kinetic energy of a baseball traveling at nearly 100 km/h.

If this particle was to travel 100 000 light years across the Milky Way, that trip would last only 10 second from its point of view, due to the time dilation.


150. Besides the ordinary matter we are all familiar with, there are all kinds of matter that is either theoretical or recently discovered. We now separate matter into baryonic and non baryonic madder, and light and dark matter. Baryonic matter is made of standard atoms and molecules, and subatomic particles like protons, neutrons and electrons.


Conclusion

As you can see, universe is full of surprises, and we, as a human race, had our own share of adventures and crazy anecdotes to add to it!

So here we are, at the end of the road.
