Ever wondered what there is between the stars? Dr Naomi McClure-Griffiths not only wonders about it, she’s on a mission to find out.
Naomi is fascinated with the life of stars, the behaviour of interstellar gas, and how gas and stars interact. “As an astronomer, I’d like to understand how the galaxy formed and how it’s living its life,” she says.
“The galaxy is much more frothy and bubbly than we ever thought. It looks like the head on a glass of beer.”
Very large stars, 8-20 times the size of our sun, experience dramatic supernova explosions that push gas out of the galaxy via solar winds travelling at up to 1000 kilometres a second.
It is these solar winds that blow bubbles in the gas between the stars, creating a frothy, foamy appearance.
