UNITE: Unistellar Network Investigating TESS Exoplanets
NASA’s Transiting Exoplanet Sky Survey mission has identified many new exoplanets! Astronomers now need your help to characterize the orbits of these exoplanets as a first step in learning about them. Join the worldwide Unistellar global network of amateur and professional astronomers working to document the timing of exoplanets' transits (a “transit” happens when a planet passes in front of its star, briefly blocking the starlight). We are tracking both the frequency and length of transit periods to better describe the orbits.

![Three planets and a bright star appear against a backdrop of pinpricks of light of distant stars. The largest, a light-brown orb with the swirly appearance of a gas giant, fills the right hand side of the frame. In the lower left, just in front of the big light brown body, we see a smaller, darker body, its top surface lit by the light from the bright star in the upper left. The third planetary body, the smallest yet, lies between the smaller body and the star. It casts a long shadow across the dust of space.](https://science.nasa.gov/wp-content/uploads/2023/12/gasgiantjpl.jpg?w=4096&format=jpeg)
What you'll do
- Use your own telescope to observe newly discovered exoplanets and collect information about its transits to help characterize its orbit.
- Coordinate with other citizen scientists and researchers around the globe to track and learn about these new worlds.
Requirements
- Time to get started: 5-15 minutes to complete the tutorial; observations take 1+ hours
- Equipment: Unistellar or similar telescope
- Knowledge: None. An in-project tutorial provides all instruction needed.
Get started!
- Visit our project get started page.
- Pick your target based on your location and note the observation details.
- 10 minutes before the predicted transit, point your telescope at the target (detailed instructions provided).
- Observe the system and fill out an online observation report.

![This map of the world shows land in grey with light grey country borders and a dark blue ocean. Overlaid on the map is an irregular blue shape and a grid of symbols indicating the area from which the target event may be observed.](https://science.nasa.gov/wp-content/uploads/2023/12/exoplanetprediction1-1.png?w=4096&format=png)
Blue stars & shading = you can observe the entire event.
Yellow triangles = you can observe the entire event but you may have brief tracking difficulty due to the high altitude of the target star.
Orange diamonds = you may miss the start or end of the event but your data will still be useful.
