Weekly Space Hangout: November 9, 2022 – Untying an Early “Cosmic Knot” with Dr. Andrey Vayner

But how exactly does a long string of seemingly random “ones and zeros” get transformed into such amazing visual imagery? Tonight, Kevin Gill, the image processing “magician”, is with us to give us an introduction into how to access the public archives as well as how to process their data. Read More
