The first exoplanet found outside our solar system is 51 pergasi b, a hot jupiter thats bigger than Jupiter and is closer to its parent star than Mercury is to ours, this star broke all physical laws being the type of planet it is and its distance from its star, sometimes also called Bellerophon.

Stars do not twinkle, its the light from stars that distort in the atmosphere when it hits pockets of hot and cold air, called Stellar Scintillation

In Earths sky the Moon and Sun are both the same size, the only planet/moon in the solar system to have that relationship, and the only moon to completely eclipse the Sun.

The Andromeda galaxy is 2.5 million lightyears away from us, it is on a collision course with the milky way in around 3-5 billion years, by then the Sun would be a red giant.
