 Hey, my name is Nico and I'm a deep-sky astrophotographer. 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 or the period luminosity relationship for Cepheid 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
