Frequently Asked Questions
May I copy unaltered individual images, animations, or video to include in my term paper, presentation, or website?
Yes, if it for educational or non-commercial use. Images/multimedia should include the credit line Palomar Observatory/California Institute of Technology unless otherwise stated in the file's metadata or its caption. It is your responsibility to investigate additional conditions and/or obtain permission to use images/multimedia not credited exclusively to Palomar Observatory and the California Institute of Technology.
