Summary

An astrophotographer captured over 100 hours of exposures to create a deep field image showing thousands of galaxies spanning billions of light-years, and also documented a newly discovered supernova that appeared about two weeks ago caused by a white dwarf consuming material from a neighboring star.

After capturing over 100 hours worth of exposures, I'm pleased to share my latest "Deep Field" image, containing THOUSANDS of galaxies and a brand-new supernova that just kicked off ~2 weeks ago! Timelapse showing the supernova, prints, and more details in the thread 👇

When you look closely, you can see not just the larger foreground galaxies, but impossibly distant ones that FILL the view. Many of them are over a billion light years away! I'll have high-resolution fine art prints available for the next 4 days here: cosmicbackground.io/pages/civiliza…

In this video you can see how a star seems to appear from nowhere. That's the supernova! A white dwarf in a binary system gained ~1 Billion times its luminosity from consuming its neighbor. This video was made from using a single night's capture both before and after the event.
