It's not planet X, the source is the sun of our sun. It's a gigantic sun with rings like Saturn except they are radiation rings.

Our sun and solar system orbit this gigantic sun with radiation rings, it's name is Acloyne. There are seven solar systems orbiting this gigantic sun, these 7 are the Pleiades.

Each sun is the center of a solar system, and Alcyone is the center of seven solar systems.

The rings of Alcoyne extend themselves across many light years; they are immensely huge and our solar system is entering into these rings.

Scientist have not spotted this great sun, as the third dimension is not the only dimension in the universe. But the effects of it as starting to be felt. This will only increase as we pass through the rings.
