Our solar system is locked in a strange kind of 'cosmic bubble'

Astronomers say the mysterious "cosmic bubble" around our solar system is the result of events that began 14 million years ago today.

Experts have known for 40 years that there are very few stars within a vast area around our solar system for about 1,000 light years, while new stars are forming in large numbers outside of it.

In a new study, experts have discovered, with the help of astronomical observations and sophisticated computer simulations made in recent years, that this "cosmic bubble" began to form 14 million years ago with a supernova explosion.

When a star many times the mass of the Sun explodes in a massive explosion, a great deal of energy, shock waves, and star matter are scattered around. This is the so-called supernova.

New stars started to form in large numbers on the outer edges of this cosmic bubble, which turned into shaped because of the supernova 14 million years ago, and this trend keeps these days.

At the same time, the bubble spread, and today it is about 1,000 light-years across.

In the course of modern research, experts have so far not only traced the full history of this cosmic bubble, but also determined its structure.

There may be a large number of these bubbles in the universe that require further research
