Legacy Survey of Space and Time

LSST camera

Vera Rubin

Vera C. Rubin observatory, currently under construction in Chile, will conduct an unprecedented, decade-long survey of the optical sky called the Legacy Survey of Space and Time (LSST). Once Rubin Observatory begins operations it will revolutionize the field of astronomy and what we know about the Universe.

Rubin Observatory is not just a telescope, it’s a complex, integrated system consisting of an 8-meter class wide-field ground-based telescope, a 3.2-gigapixel camera, an automated data processing system, and a public engagement platform. Rubin Observatory seeks to enable science in four main areas:

  • The nature of dark matter, and understanding of dark energy 
  • Cataloging the Solar System 
  • Exploring the changing sky
  • Milky Way structure and formation

This oldest-ever snapshot of dark matter in the universe offers the tantalizing possibility that the…
