πŸ₯³ Incredibly well deserved. Sending you a massive high-five. We'll need to properly whoop together the next time we see each other in person.

Huge congratulations to the #Stirling Astronomical Society on their 40th birthday! πŸ₯³

If you're in the area, do join them for a cosmic celebration with music and stargazing (weather Gods willing).

Environmental Impacts of Food Production What are the environmental impacts of food production? How do we reduce the impacts of agriculture on the environment?

I don't know - but looking around the resources linked to the UN figure, I found this awesome page. Looks like it is indeed to do with the farmed prawns πŸ€·β€β™€οΈ

A bar chart showing the kilograms of greenhouse gas emissions per 1000 kilocalories.  Shellfish, Beef and Lamb emit the most. Breads, legumes and nuts the least.

Just finished an audio clip for a kids podcast, sharing my top tip for "saving the planet". After double-checking they were sure they didn't want to hear about the planetary defence team's plans for diverting killer asteroids in space, I decided to go with this data from the UN. #EatVeggie #EatVegan

If your pop-sci book shelf is looking for a new addition - Emma Chapman's Radio Universe is coming out this week. It's genuinely delightful and well worth picking up a copy!

Pink sunrise sky looking at old tenement blocks.  The moon is just setting over some chimney stacks and a seagull has positioned itself perfectly right in front of it.

I'm not entirely sure Neil - but please do encourage your daughter to send the centre an e-mail (contacts on the above web link). They are a super nice bunch of really dedicated people and it's in a really lovely part of Scotland.

Remember "NASA makes 'emergency' decision as chances of 'city-destroying' asteroid hitting Earth rise to 1-in-43", that turned out to not be on a direct collision course after all?

Well disappointingly it's not going to crash into the moon either. Party-pooper ☹️ πŸ”­πŸ§ͺ

Anyone watching the UKGov hearing on the STFC cuts yesterday would have also heard the rumba cha-cha-cha music in the background. Turns out it was a dance class for MPs lead by National Treasure and legendary icon Angela Ripon. The Sun newspaper was not impressed!
