In this episode:00:46 An unusual γ-ray producing microquasarA type of binary-system known as a microquasar has been found to be firing out γ-rays at high energy-levels, which may make it a candidate to be a long-theorized natural particle-accelerator known as a PeVatron. These objects are thought to be a source of galactic cosmic rays, the origins of which are currently a mystery.Understanding how this microquasar works could also help researchers learn more about full-sized quasars — monstrous objects centred around supermassive black holes, which are too distant to study easily.Research Article: Alfaro et al.News and Views: High-altitude particle detector spots a second Galactic microquasar09:27 Research HighlightsThe comb jellies caught fusing their bodies, and an ancient burial site reveals that Classical accounts of Scythian culture appear to be true.Research Highlight: Two comb jellies fuse their bodies and then act as oneResearch Highlight: Evidence of dead people posed on dead horses found in ancient
