Things astronomers do..
study the universe and have lots of fun doing it!
Design, build, use telescopes, spacecraft, cameras etc (computers)
Analyse data (computers)
Build theoretical models (pencil+paper, computer)
Read lots of research
Publish results
Educate/supervise students, talk to schoolkids!
Go to great places (observatories, eclipses, meetings, the Space Station..)
