When I took some astronomy classes in the early 2000s, Jocelyn Bell was absolutely credited. In her own words:
It has been suggested that I should have had a part in the Nobel Prize awarded to Tony Hewish for the discovery of pulsars. There are several comments that I would like to make on this: First, demarcation disputes between supervisor and student are always difficult, probably impossible to resolve. Secondly, it is the supervisor who has the final responsibility for the success or failure of the project. We hear of cases where a supervisor blames his student for a failure, but we know that it is largely the fault of the supervisor. It seems only fair to me that he should benefit from the successes, too. Thirdly, I believe it would demean Nobel Prizes if they were awarded to research students, except in very exceptional cases, and I do not believe this is one of them. Finally, I am not myself upset about it - after all, I am in good company, am I not!
That said, yeah, I think she absolutely should have been awarded the Nobel prize. But while she did not, she has the admiration --- rightly so --- of many a budding astronomer.
See also Rosalind Franklin who first discovered DNA's double helix structure (three men later received the Nobel Prize for this finding).
And more examples here.
The nobel prize is a fucking self congratulatory sham anyway if you read about its history
