Hey.

Here is the answer.

______________________________

◆Cosmic strings are an insane idea, but the craziest part about them is that they could actually exist. Cosmic strings are slight defects in the fabric of space and time that were created at the beginning of time, left over from the formation of the universe. 

◆Ghost galaxies, also called dark galaxies, are galaxies that have very few stars. They’re so inefficient at making stars that they’re thought to be mostly composed of gas and dust, making them basically invisible.

◆A preon star is something that could follow a quark star. As a star is compressed to the point where it becomes a quark star and is still massive enough to continue its collapse, scientists believe that the quarks themselves could break down into these theoretical preons.

◆The idea of Chthonian planets became popular thanks to an extrasolar planet nicknamed Osiris. NASA scientists were baffled when they detected carbon and oxygen for the first time in an atmosphere outside of our solar system. However, Osiris’s atmosphere was seen to be rapidly evaporating.

◆ ocean planets, or water worlds, are thought to be composed entirely of vast, uninterrupted oceans. The idea of water worlds became popular when NASA announced the existence of two planets outside of our solar system: Kepler-62e and Kepler-62f. These planets are thought to be water worlds that could harbor a wealth of aquatic life.

◆Quark stars, also called strange stars, are thought to be composed of a soup of quarks—the fundamental constituents of matter. Astronomers believe that these stars can be created after a medium-sized star (about 1.44 times the size of our Sun) has run out of fuel and has entered the collapsing stage of its lifetime. As it collapses, it squeezes protons and electrons together, eventually forming neutrons.
