See the Great Comet of 2020 in incredible detail.

While this video will look just fine if you don't have the hardware to support HDR, it will look an order of magnitude more brilliant if you do.

How to view in HDR Mode:

Easy:

Watch directly via the Youtube App on your High Dynamic Range capable SMART TV. See your TV's owners manual to confirm that you have an HDR Television. To confirm you are watching in HDR, find the 'stats for nerds' option (looks like a traffic light) on this video while it is playing. Confirm that the colorspace being used is "BT2020"

Harder, On your PC:

To support HDR you will need an HDR capable Monitor (or TV) connected to your Desktop PC or Laptop. Your graphics card must support HDR 10 bit or higher color modes. (Most nVideo GeForce/Quadro and Radeon cards support this.) Your operating system must support HDR: Such as Windows 10. You must have HDR support enabled in your operating systems display settings (Enable "HD Color Mode). Your Browser must ALSO suppport HDR....Firefox does NOT play youtube videos in HDR. Google Chrom and Microsft Edge browsers will play HDR videos. To confirm HDR video is playing, you'll see a red "HDR" tag on the gear on the lower right hand corner of this video.
