The Lindsay-Shapley Ring has an incredible story in how it formed. You might be seeing the yellowish center in the image we added, right? It looks beautiful, but this ring actually took that yellowish nucleus as its own. It was part of a normal spiral galaxy, yet the ring took it as its own after it potentially collided with that other galaxy. The ring is 150,000 in diameter and was not always a ring. Thus, when it collided with the other galaxy, it just punched through it. Gravitational forces caused dust in the galaxy to condense, leading to the formation of stars. Then the full expansion happened, leading to the ring forming too.
Our Earth 300 million years ago was going through quite a big change. The first amphibians and reptiles began to form after a large extinction period that killed off 70% of the world’s species just a few million years beforehand. Many of the world’s winged insects began to form in this time. Life burst out possibly due to the highest-recorded atmospheric oxygen level for the Earth. Not just animals came from this, new species of plants and trees came too. This includes coal forests, scale trees, ferns, giant horsetails, and even corals in the seas and oceans.
