To create true-color images of an astronomical object, you can take photos of it in red, green, and blue wavelengths using filters, and then process these images together to get an accurate photo. You can also mess around with those color channels and/or process images of different objects together to get weird fun experimental art like this. These images were taken remotely at the MDM Observatory by Nicole Melso for classroom use, and edited in SAOImage ds9. They feature M1 (the Crab Nebula), M74, M35, and M82 (the Cigar Galaxy).
Hi, I'm Sarah, I'm a junior at Columbia majoring in Astronomy (and maybe concentrating in women's, gender, and sexuality studies? we'll see). Academically, I'm into instrumentation, public outreach, and science communication/education. Outside of school, I'm by and large an art person. I've always been an artist, and art is always going to be an important component of how I define myself. I'm really passionate about fostering both my love of art and my love of astro, and even though for me personally they don't often overlap in practice, I think the things that drive me towards both of them are the same.
