About my book, “Outer Solar System Moons: Your Personal 3D Journey” (Printed and digital copies can be purchased at etsy.com/shop/ETExists)...
I got the itch to author this after the success of my colleague’s book, “Mars: Your Personal 3D Journey” by @AntonioParis! 1/n
All of the 3D images were made in @Photoshop and the final draft was made in @powerpoint. While the entire process was very arduous and frustrating at times, the result has been nothing short of rewarding, as the book is finally starting to sell bigly! The very positive...2/n

Next year the biggest astronomical event visible from the UK will be a Partial Solar Eclipse on 10 June 2021. Some parts of the world will see an Annular Eclipse. I've got plans to capture the Partial one from here.
This will, weather permitting, be only my second go capturing a Solar Eclipse. My first time was back in March 2015. I had my Sky-Watcher Telescope, Canon 1200D camera and Nikon L810 camera for pictures. This is one of the pictures I took.
Next year's eclipse will only be about a third obscured from here and the rest of the UK. Nevertheless I'm planning to use my Sky-Watcher again, and Celestron telescope to capture the big event. This is the smiley face view I hope to see.
After the Geminids meteor shower the next big Astronomical event is a Solar Eclipse on 14 December. However not visible from the UK. Handily there is a big Astronomical occurring after that, visible all over the world. A super conjunction on 21 December. Jupiter and Saturn.
Jupiter and Saturn will appear so close together they will nearly look like one object. Should be an amazing sight in Binoculars and telescopes. Also a great photo opportunity. Will be tricky to observe and capture from the UK though.
The planets will be very low on the horizon from my location and mid northern latitudes. Won't be possible for me to see them from my house so I'll have to take all my doings to another spot. I'll need a clear southern horizon looking to the southwest. I know the perfect spot.
Good morning! My week on People of Space is dedicated to the theme of women in space and STEM. We've looked at the @UNOOSA#Space4Women programme, and space books by women, with forays into the works of Margaret Cavendish (1600s) and Barbara Ward (1970s).
And what a week it's been! Women are pretty thin on the ground in NobelPrizeLand, but first of all was the good news that Andrea Ghez was awarded a Nobel Prize for Physics for her work on black holes (with Reinhard Genzel) nobelprize.org/prizes/physics…#WomeninSTEM
Good morning everyone! I've just been in an amazing panel about satellites and #Space4Women - I'll post the link to the video here or over at my regular account when it's up. #WSW2020
Today is pretty flat out - later on I'll be chairing a session at the Australasian Space Health Symposium as well as presenting a paper. Is the paper finished? What an interesting question which I will decline to answer at this time. #WSW2020
Time for my third book in this series on space books by women: Spaceship Earth (1966), by Barbara Ward, Baroness Jackson of Lodsworth - a pioneer in the philosophy of sustainability and social justice #Space4Women#WSW2020
The concept of 'Spaceship Earth' is usually associated with Buckminster Fuller and his 'Operating Manual for Spaceship Earth' (1969) - but Barbara Ward published her book 'Spaceship Earth' in 1966. #Space4Women#WSW2020
The origins of 'Spaceship Earth', however, actually pre-date the Space Age! In 1879, the US economist Henry George wrote: 'It is a well-provisioned ship, this on which we sail through space'. More history here: en.wikipedia.org/wiki/Spaceship…#WSW2020
Pulsars are effectively laboratories in Space that allow us to probe the behaviour of dense matter & its fundamental constituents
But what about laboratories? Nuclear experiments? Particle accelerators? The most powerful heavy ion colliders we can build on Earth? Why do we need to study Pulsars so far away in Space?
Nuclear experiments probe matter at the density of a nucleus of an atom. But what is the nature of nuclear interactions at 10x nuclear density? Known stable nuclei have same number of neutrons/protons. But Pulsars ("Neutron Stars") have many more neutrons than protons!
So ten years ago, when I was awarded the prestigious Alexander von Humboldt @AvHStiftung for postdoctoral research in Germany, I jumped at the chance 😉 #themissuniversemoment 😂
I spent a couple of amazing years doing research at @UniHeidelberg, a German Excellence University and also its oldest 🤓🏰
My workplace was the Institut für Theoretische Physik on 16, Philosophenweg (Philosopher's walk) (private house of Nobel prize winning nuclear physicist Hans Jensen) with a breathtaking view of the Altstadt (old town) 😍
Optical Systems Engineering!!! What is it? Why do we do it? How do we do it? I’ll try explaining in just a few tweets.
For context we’re talking optical imaging cameras for satellites for earth observation, but the same ideas and processes are relevant for astronomical telescopes and other forms of payload or ground based equipment.
Like a traditional spacecraft-level system engineer, the Optical System Engineer is responsible for the whole optical system -> requirements, design, analysis, manufacture, assembly, verification and even sometimes in-orbit operation.
