Now, we make precise brightness measurements to study exoplanets transiting their stars.

The NASA Transiting Exoplanet Survey Satellite (TESS) is searching millions of stars for transiting planets.

Are you interested in… • observing TESS candidate planets

with ground-based telescopes • working for independent study credit

…?

Are you willing to learn… • how to observe transiting planets with

the SBO telescopes • how to work collaboratively in a world-

wide community of observers

…?

Are you… • creative • curious • kind

…?

I am looking for roughly 4-6 students to join a team to observe exoplanets from SBO.

To apply, email zach.bertathompson:

• a brief resume/CV • your general evening availability

during spring 2020 • a cool astronomy plot you made and a

brief description of something interesting you see in it
