Our #HubbleTopImage features a galaxy 😈 which rules the neighbourhood!⁠ ⁠ ESO 306-17 is a large, bright elliptical galaxy in the southern sky of a type known as a ‘fossil group’ due to their isolation. But are they really like fossils – what is left of a once-active community – or do they have a more sinister history?⁠ ⁠ Did this galaxy ‘gobble up’ its neighbours? 🍴⁠ ⁠ Fossil groups may be the most extreme examples of galaxy cannibalism – hungry systems that don’t stop eating until they have devoured all of their neighbours.⁠ ⁠ For more information check the link in bio.⁠ ⁠ 📷 NASA, ESA, and Michael West (ESO)⁠ ⁠ #ESA #Hubble
