NASA Astronomy Picture of the Day is an archive back to 1995 of photographs and videos taken by NASA.

Go to and click on "Discover the Cosmos!" at the top left of the screen to get to the archive.

Each day of the year has a picture and description of said picture on the site. Possible activity with the students would be to have them look up their birth date (month, day, year) and composing a report of their "picture of the day". I did this with my class and it was well received.
