Are there any elements found in space but not at all on Earth?

AI Thread Summary
The discussion centers on whether there are elements found in space that do not exist on Earth. Participants clarify that all naturally occurring elements are present on Earth, while synthetic elements are not found naturally. There is a mention of transuranic elements detected in stellar spectra, but these are not naturally occurring on Earth. The conversation touches on the coincidence of having every possible element on Earth and speculates about dark matter potentially being a new element. Ultimately, the thread emphasizes the importance of sticking to established scientific knowledge rather than speculation.

I don't know, but give me five minutes on the Internet and I'll bet I could find out!

What are you waiting for? I looked for about fifteen minutes and found nothing.
 
search for 'transuranic elements in spectra of type A stars' and you will get some information. What I got was outside of my understanding comfort zone -- e.g., 'process -r' -- so you can play with it on your own. My possbily wrong take: the largest stars undergo nucleosynthesis.
 
Nanodiamond. It can only be synthetically produced on earth. I do believe (:

30 seconds later:

In total, 118 elements have been identified. The first 94 occur naturally on Earth, and the remaining 24 are synthetic elements.

No.
@ETsmyhomeboy - nanodiamonds are carbon. Carbon is an element found on Earth. You and I have carbon atoms in us.
 
@PeroK Correct me please, but I think the OP wanted elements found in other star systems which precludes synthesis by humans on earth. And synthetic elements definitely are not found naturally occurring on Earth, I'm sure of that. So, yes on that part.

As far as my 30 seconds research goes, all naturally occurring elements are found on Earth. There are no elements that cannot be found on Earth.

Thank you. That is what I wanted to know. Now, knowing this...the universe is a big place, and it's been around a long time. How is it that we have every possible element that was ever created here on Earth? I'm not suggesting you're wrong. It just seems a little coincidental. Could dark matter be some "new" element. I'm just throwing ideas around.

@zuz Please - no 'throwing ideas around' that gets into speculation. PF is about known Science, as in textbooks and journals. The general discussion forum here is more flexible for that. Thread closed.
