What astronomical object could the Christmas Star have been?🎅⭐
That's the topic of our Public Talk this month, as Dr Becca Whitehead considers whether a comet, supernova, planetary conjunction or another phenomenon may have been responsible for the key event in the Christmas narrative. 🤔☄️💥🪐

For the reading list! great new paper on the impact of satellite megaconstellations. 🔭
By 2040, ~40% of the images from Hubble Space Telescope, and more than 96% from new and future space telescopes like SPHEREx, ARRAKIHS, and Xuntian will be contaminated by internet satellite constellations.

This is a significant development. The Cambridge Unite branch represents hundreds of support staff at the University in both teaching and research departments. They have also recent experience of organising strike action.
The insulting 1.4% pay offer from the universities on top of years of sub-inflation pay rises has led our members to vote for strike action in the 2025-26 pay round. The results are as follows:
Turnout: 54.39%
Yes: 83.16%
Against: 16.84%
We now have mandate for strike action!
