7. Pulsars – what are they? Well, Pulsars are “dead” stars that produce no more energy other than pulses of radiation. In the past, researchers thought that the rhythmic pulses were an attempt of communication by aliens, but once Pulsars were understood, the theory was quickly abandoned. Today, that same rhythmic pulse is used by our spaceships for navigation, kind of like a space-GPS.

8. Sometimes mentioned in Sci-Fi and science shows, “Quasars” are an interesting phenomenon? The word is a shortened version of “QUAsi-StellAr Radio Sources” and they actually are discs of matter, surrounding supermassive black holes in the center of galaxies. They’re considered to be the brightest objects in the universe, with over 200,000 known to exist. (Credit: ESO/M. Kornmesser)

9. Ever heard the term “Magnetars”? Me neither, but it’s a real thing. They are actually neutron stars, 20 kilometers (10 miles) in diameter, that have such a strong magnetic field which is capable of crushing the star’s crust and cause “planetquakes” (that’s when a whole planet shakes!) If you were to be within 1000 kilometers (620 miles) from them – the magnetic field would vaporize you.

10. Here’s a scary one: “Galactic Cannibalism”. What it is, is when a big galaxy absorbs a smaller one into itself. We currently believe that this can happen to our galaxy (The Milky Way) in about 4 billion years, when it will collide with the Andromeda galaxy.



This is our universe, in all it's splendor and glory!
