This week, Claire talks to Tim O’Hara from Museums Victoria about his voyages on the RV Investigator, examining deep-sea creatures and mapping underwater landscapes, in the lead-up to his talk on Wednesday 16 August for National Science Week; and Chris takes a look at the theory that the unexpectedly bright galaxies in the early universe seen by the JWST may instead be “dark stars”, enormous objects powered by dark matter.
