Eclipsing Binary Patrol

An "eclipsing binary" (EB) is a pair of stars that orbit one another, oriented so that one star sometimes blocks our view of the other star. At Eclipsing Binary Patrol, you will examine space telescope data and help unravel the mysteries of these multiple-star systems. You’ll help discover new eclipsing binaries by helping weed out imposters -- objects that blink but are not eclipsing binaries. The science team of this project is mostly composed of citizen scientists.

Eclipsing Binary Patrol is also available in French.

What you’ll do

  • Complete the in-project tutorial.
  • Examine three kinds of data from NASA’s Transiting Exoplanet Survey Satellite (TESS) mission: two graphs and an image. 
  • Answer four questions about the data.
  • Learn how to research your favorite objects using professional catalogs (scroll to the bottom of the page).
  • Connect with other people with similar interests via Zooniverse TALK bulletin boards.
  • Fill out this form to join the advanced user group and participate in meetings with the science team.

Requirements

  • Time: 10-15 minutes to complete the tutorial
  • Equipment: Web-connected device.
  • Knowledge: An in project tutorial provides all the instruction needed for the basic three-part task. Experience with the Planet Patrol project can be helpful.

Get started!

  1. Visit the project website.  
  2. Follow the tutorial, read the research page, and read the F.A.Q. to learn what to look for in the data.
  3. Help separate the good eclipsing binary candidates in TESS data from the bad ones!

Learn More

Read the Research Pages on the project’s website to learn more about the science of multiple star systems and the planets that orbit in them. Binary stars continue to yield surprises even after hundreds of years of study. Eclipsing binaries you help find will be targets for future exoplanet searches.

Image includes three displays of data. On top is a line graph with brightness on the vertical axis and time (days) on the horizontal. The data appears as is tight black horizontal band around 1.00 brightness. This band moves subtly up and down through time, with two distinct sets of evenly spaced sharp descents, one down below 0.95 and the second below 0.90 brightness. The second display is a scatter plot with brightness on the vertical axis and Orbital Phase (Primary Eclipse at 0.1…) on the horizontal axis. Data appears again as a broad band clustered at 1.00 brightness, with two distinct sets of descending data points, one of which has data points below 0.90 and the second with data points below 0.95. The third display is a five-by-five pixel box. Pixels around the edges are in dark blue. A single yellow box with a single green box just below it appear in the center.
Example of the three kinds of data that participants are asked to inspect as part of the Eclipsing Binary Patrol project.

Eclipsing Binary Project logo A black circle is surrounded by a multi-color (turquoise to fuchsia) band. Inside from the band is a ring of colorful, small dots. Inside from the dotes is a white ring. Inside that ring is a four color band, each color occupying one quarter of the band. Inboard of that is black. In the middle of this black is a gold and orange circle.
