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
You can find more details about the Australasian Space Health Symposium here. I'm pretty sure it's not too late to register (it's free) adastravita.com/space-health-s… #WSW2020
This will be the first time I've chaired a virtual session so I'm a bit nervous I'll mess up the technology!

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
Then the Nobel Prize for Chemistry was won by Emmanuelle Charpentier and Jennifer A. Doudna "for the development of a method for genome editing." nobelprize.org/prizes/chemist… #WomenInSTEM

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

So let's see what a Pulsar looks like from the surface to the interior
The outer crust of Pulsars is made of nuclei (like iron) in a sea of electrons. As we go deeper inside, the nuclei are more rich in neutrons (like exotic nuclei in our labs)
As we enter deeper into the Pulsar, extreme densities start to distort the nuclei, twisting them into strange shapes, resembling "pasta" 🍝 (yes, you read that right) 😉

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!
