A Giant Galaxy Orbiting Our Own Just Appeared Out of Nowhere (VIDEO)

Astronomers scanning the skies just got a huge surprise. They discovered a gigantic galaxy orbiting our own, where none had been seen before. It just came out of nowhere. So, just how did the recently-discovered Crater 2 succeed to pull off this feat, like a deer jumping out from the interstellar bushes to suddenly shock us? Even though the appearance may seem sudden, the Crater 2 has been there all along. We just never saw it.

Crater 2 is a dwarf galaxy, satellite of the Milky Way. Crater 2 was only discovered in 2016, which may seem surprising because this galaxy is relatively close to us, and has considerable dimensions, being the fourth largest satellite galaxy in the Milky Way.

Crater 2 is located approximately 380,000 light-years from us, and has an estimated diameter in the order of 7,000 light-years. This galaxy is in the direction of the constellation Crater.

Our galaxy, the Milky Way, has some satellite galaxies, with Crater 2 being the fourth largest, as previously reported. Given the proximity and dimensions of Crater 2, how could it have gone unnoticed so far? One of the main reasons has to do with the fact that this galaxy is very dark, its brightness is really very weak. Crater 2 is a diffuse galaxy.

Some UFO theorists claim “Galaxy” is in fact a spaceship, spaceship which has Stealth technology.
What do you think? How can galaxies appear “suddenly”?
