Rubin Observatory's COSMOS Field

• A new image from the NSF-DOE Vera C. Rubin Observatory captures over half a million galaxies in the COSMOS field.
• The field is a patch of sky larger than the full moon, selected for its relative lack of bright Milky Way stars, providing an unobstructed view of distant galaxies.

Observations and Details

• The central panel reveals a vast collection of galaxies, while panels 1-10 provide zoomed-in views of specific regions, highlighting diverse shapes and sizes.
• Some captured galaxies are billions of light-years away, representing light that has traveled for vast epochs to reach Earth.
• The region has been previously studied by both the Hubble and Webb telescopes due to its clarity.

Future Objectives

• As part of the ten-year Legacy Survey of Space and Time, the Rubin Observatory will revisit the COSMOS field every few days.
• These frequent revisits will enable astronomers to study the dynamic nature of the field and document how the sky changes over time.
