A shockwave from a catastrophic supernova explosion may have triggered the birth of our solar system when it crashed into a cloud of gas. Remnants of matter ejected from the ancient blast can still be found in samples of primitive meteorites today. Scientists studying this process claim the supernova explosion that caused the birth of our sun may have also given rise to our solar system's rotation, allowing the formation of the planets, including Earth. Scientists have shown before that if a supernova exploded near the nebula like cloud that would eventually become the Solar System, it would create indentations – which they call “fingers” – injected with radioisotopes. In their latest work, some scientists expand the model to explain the angular momentum (spin) that made dust clouds form into planets, rather than simply collapsing into the Sun. They found that the fingers produce the spin, not only determining the composition of the planets, but creating the conditions for their existence. Some dramatic observations of a supernova.... Our Solar System formed only 4.5 billion years ago. That doesn't seem like such a long time compared to the age of our universe, (which is 14 billion years old). For a scientific theory this is a pretty good one, and everyone loves explosions so its a fun way to understand what observable evidence we have....

A supernova could have created our solar system.

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
