Question for Tom on Astronomy Day

[TomK]

Thanks, AKpilot! For Astronomy Day (it's tomorrow, Saturday, April 21st), NASA released this video of the Lagoon Nebula. The first part of the video includes actual images of the nebula taken by the Hubble. When it starts rotating it's CGI. On the other hand, the data used to create the CGI part of the video are real and were collected by both the Hubble and ground-based observatories including those on Mauna Kea, so we know the 3-D picture and that's what NASA is representing in the video.
