Hey, my name's Nico and I'm a deep sky-ached photographer. This is a picture of a supernova remnant I captured in 2018. It's called the Spaghetti Nebula and we know that it's a very ancient supernova remnant, meaning the star exploded a long time ago because the supernova remnant is really big in the sky and it's also really dim, meaning these gases have taken a long time to expand out. And one interesting thing about a supernova remnant that I've always thought about is the fact that it's actually three-dimensional. So this is actually a sphere. But how could I represent it in three dimensions? Well, astronomers have been getting better and better at calculating stellar distances. First through parallax measurements, which are good for close-by-stars. And then later through Levitt's Law, where the period luminosity relationship for C.F. had variables, which lets us go even further out. And I use these stellar distances to break apart my picture into three dimensions and get really cool visualizations like this one where I'm using actual science to try to create a 3D scene for my 2D picture.
