Astronomer Royal for Scotland | Catherine Heymans @astroroyalscot.bsky.social · about 21 hours ago
A truly epic day at Winchester Science Centre and Planetarium talking with 600 primary school kids for "Ask the Astronomer Royal Anything"! Aliens; black holes; how did the Earth, Sun, Galaxy form?; how did it all begin?; how will it all end? I do so love my job. 🥰🔭🎢 📷: Robin Mair
Catherine sat in the floodlights inside a planetarium with a giant Saturn and Neptune projected on the wall behind her.

Great #timekeeping article here which took me on a real journey! Short version: adding leap seconds ("27 times since 1972") has led to problems for computer systems before and the next one might have to be subtracted, which has never been done at all! #ITeachPhysics edition.cnn.com/2026/10/1….
Leap seconds have righted global clocks 27 times. So why do timekeepers want to kill it? | CNN

An international meeting is considering a fundamental change to timekeeping, potentially severing the ancient link between time and the motion of the Earth.

Physicist Chien-shiung Wu (1912-1996) #histsci 🧪🐡👩🏻‍🔬🎢 #ald26 #AdaLovelaceDay

Happy birthday #physicist Chien-shiung Wu (1912-1997), who came up with a truly beautiful experiment to test whether the weak force conserves parity (whether beta decay would be the same if reflected in the mirror)! 🧪🐡👩🏻‍🔬 #histsci In my print on the left I show Wu in her lab & a schematic diagram of
Linocut print of Chien-shiung Wu in indigo wearing a lab coat and holding a schematic diagram of her famous violation of parity experiment (in blue and indigo) on the left side. The right side shows the mirror image except in the schematic diagram. The left side schematic shows a C shaped electromagnet open to the left. The top is labeled S, the bottom is labeled N and the middle is wrapped in wire drawn as a circuit diagram schematic with parallel lines to indicate a power source and left arrow on top wire, right arrow on bottom. Between the poles of the magnet is a big blue dot to designate Cobalt-60 with many tiny dots as beta-decay electrons, the majority going downwards to N pole. On the right, everything is flipping except most electrons go upwards (and and N and S poles are flipped).
