What is the Vera C. Rubin Observatory's main job?
A 10-year time-lapse survey of the southern sky, the LSST.
- Imaging one galaxy in extreme detail
- Re-imaging the whole southern sky every few nights for 10 years ✔
- Listening for radio signals from aliens
Why: Rubin's 8.4-meter telescope and the largest digital camera ever built cover the whole visible sky every few nights. The result is a movie of the sky that catches asteroids, supernovae and other changes.
Huh, didn't know that: It is named after Vera Rubin, who gave the first convincing evidence for dark matter.
Rubin takes a selfie of the whole sky every few nights. Talk about commitment.
