After the tornado warning expired, Bobby and I resumed working on his nebula poster. We both thought a bit more material would be nice, so we picked one more star-forming, one more planetary, and one more reflection nebula. We found an excellent image that showed the color-coding used for the different elements present in nebulae, so I explained to Bobby how astronomers use filters to track the distribution of the elements in these gas clouds. While in the computer lab, we had to move to another computer for printing purposes, and Bobby's friend sat at the one we had originally been using. The friend was checking out the nebula images, and pointed to one that we had studied, and Bobby explained very professionally and accurately what that nebula was: NGC 1999 in Orion - I was very proud of him!
