I got a question today for Planetary Radio Q&A that I couldn't answer, being pretty ignorant about solar system formation research. Can anybody help?
QUOTE We know from the metal composition of our solar system that the Sun is at least a second or third generation star. It made me wonder if it was possible that some of the comets or other KBOs that we witness might be from the Sun's predecessor star or stars. If not, could such bodies exist a bit further out? I should think it would be fantastic to be able to investigate such objects. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

A marvellous quote, Bruce, music to my ears. It's good to know that someone is not making conservative assumptions. As I read the history of astronomy they have a pretty poor track record. It took the newer science of geology to give us the right timescale for a start, and the spatial extent of the visible universe was only properly recognised in the 20th century.
Even geology has had its blind spots however: continental drift comes to mind. The problem here was refusal to see something because there was no ready mechanism to explain it - exactly the reason why no one was looking for Sedna. Not looking for things that you don't expect may make sense in oil exploration but it's a cardinal sin in astronomy. |
