One of the things that I love about research is the bringing people smart talented people together and then watching how everyone's skill sets bring us to some cool new understanding of the Solar System

Thank you for the kind Birthday messages. My niece got me a brilliant spacey card. 🔭 🧪

WOT?!?!?! 🌟💥

Did you see this image of supernova remnant Pa 30?!

Bet you'll never look at fireworks the same way again!

A spherical structure made up of long, narrow, radial spikes emanating from its centre. This is the supernova ejecta. Many stars of the Galaxy surround it.

4 still photos of the beautiful #aurora display on Sat 10 Oct '26 from North #Oxfordshire, UK. The brightest part was between 7:35pm-8:45pm. I took 700+ photos for the timelapse I shared earlier so it was hard to pick 4! #SonyA7iii + Samyang 14mm lens #AuroraBorealis

I think it's a sat flare, each exposure was 10s, if this is the one?!

Treated to a lovely display tonight! Took these from the bridge over the Ythan here in Newburgh.

First sighting of the merry dancers since last winter. Birsay, #Orkney

An aurora in the northern sky. Pillars of soft light in pinks and greens with some low clouds and the silhouette of a bush in the foreground. Taken from just outside my house.

Clouds rolled in, went for a ferry ride and a walk, and then it cleared up and the show got good again! #aurora Here’s sort of a panoramic view from Stenpiren.

Broad green streak across the sky flanked by two of Gothenburg’s iconic cranes lit up in red.

Aurora spotted from North Yorkshire this evening 😀

Aurora from South West England. Can’t really make much out visually

Night landscape photo. Completely dark foreground taking up the lower third. Clouds above and below frame ‘the plough’ asterism which is near the centre. Fairly subtle purple aurora appears below and to the right of the plough

Andromeda Galaxy (M31) again. This time I used more spacer rings on my focal reducer to get a slightly faster exposure. Better than yesterday at least, right?

Fab story from Margaret Hamilton, RIP, showing why Science-Mums are brilliant scientists! When innovating at the cutting edge of technology, it's so important to bring together a wide range of lived experiences. Sad that only ~20% comp-scientists are female 👩‍🔬🧪

Often in the evening or at weekends I would bring my young daughter, Lauren, into work with me. One day, she was with me when I was doing a simulation of a mission to the moon. She liked to imitate me – playing astronaut. She started hitting keys and all of a sudden, the simulation started. Then she pressed other keys and the simulation crashed. She had selected a program which was supposed to be run prior to launch – when she was already “on the way” to the moon. The computer had so little space, it had wiped the navigation data taking her to the moon. I thought: my God – this could inadvertently happen in a real mission. I suggested a program change to prevent a prelaunch program being selected during flight. But the higher-ups at MIT and Nasa said the astronauts were too well trained to make such a mistake. Midcourse on the very next mission – Apollo 8 – one of the astronauts on board accidentally did exactly what Lauren had done. The Lauren bug! It created much havoc and required the mission to be reconfigured. After that, they let me put the program change in, all right.

i was fortunate enough to profile Margaret Hamilton in 2019. A really kind and curious person. This was my favorite story she told me:

I stacked 5 further videos of Saturn making 10 x 120s in all. Same details: #CFF160 🔭, #TeleVue 2.5x Powermate, #ZWO 585MC camera. By using masks, I was able to boost the brightness of the 5 visible moons without blowing out the planet. #astrophotography

A quick 30 minute capture of the Andromeda galaxy from my driveway tonight. This is a target I'll be going after for longer in the future!
