Astronomers Finally Weigh a Planet With No Star
Astronomers directly measured the mass of a starless, Saturn-sized planet drifting alone in space, confirming it was likely ejected from its birth system.
This week we read 292 papers from 12 journals — Nature, Science, PNAS and the rest — and summarised them for you. The best 10 are written up in full. A weekly PDF and a podcast come with it.
