Feedback is delighted by a study of how many animals produce poop that echoes the look of the poop emoji – even the lugworm, which does it upside down

The first six months of 2026 have seen bright threads in sci- fi series including Fallout and Paradise. But for pure gold, advises TV columnist Bethan Ackerley, try Star City

This image from NASA’s Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars. Globular clusters are made up of ancient stars that formed at roughly the same time from the same cloud of gas, giving those stars similar ages. Around 150 known globular clusters are sprinkled around the outer regions of the Milky Way.
