Scientists Complete World's Largest Digital Camera

Scientists have completed the development of the world's largest digital camera at a laboratory in Menlo Park, California. The SUV-sized camera, known as Legacy Survey of Space and Time (LSST), weighs about 3 metric tons and features a front lens over 5 feet wide. This colossal camera is designed to conduct a 10-year digital survey of the entire southern sky, capturing the largest astronomical movie ever made.

Key Takeaways:

  • The LSST camera, with a cost of approximately $168 million, will be shipped to the Rubin Observatory in Chile for mounting.
  • It is equipped with a 3,200-megapixel capacity, capturing ultra-detailed images with the ability to resolve a golf ball from 15 miles away.
  • The camera will be able to spot cosmic events in real time, track galaxies' changes over a decade, and unfold fresh insight into dark energy and dark matter, which make up the majority of the universe.
  • The project's deputy project manager expects the camera to uncover new types of deep-space objects and events and identify hazardous asteroids that previously went undetected.


The completion of the LSST camera marks a significant milestone in astronomical research, enabling scientists to observe and understand cosmic phenomena with unprecedented detail and accuracy. Its potential to provide insights into dark energy, dark matter, and the evolution of the universe offers a promising avenue for advancing our understanding of these enigmatic concepts.

Do You Know?

  • The LSST camera's 10-year survey will yield a 3D movie of the universe by observing changes in more than 20 billion galaxies.
  • Dark energy is the force driving the universe's ever-faster expansion, while dark matter, although it has mass, does not interact with light.
