The magnificent images released by the NSF-DOE Vera C. Rubin Observatory on June 23, 2025 – of the Virgo Cluster, Trifid and Lagoon Nebulas – were captured in just ten hours of observations. These images offer more than their beauty; They reveal millions of newly discovered galaxies and thousands of newly discovered asteroids. This remarkable efficiency of Rubin Observatory is how it will gather more information about the Universe in its first year of operations than all previous optical telescopes in human history.
Equally significant is the openness of the LSST data – it will be made accessible to as many people as possible around the world, supporting broad participation in the discovery process.
Later this year, Rubin Observatory will begin the Legacy Survey of Space and Time (LSST), a ten-year unprecedented movie and map of the Universe. LSST observations will deepen our understanding of dark matter and dark energy, stars and galaxies, and our solar system.
“LSST won’t just revolutionize our understanding of the Universe — it will transform how science is done. I’m thrilled that LSST Discovery Alliance can help multiply the impact of NSF’s and DOE’s investments in Rubin Observatory and the Legacy Survey of Space and Time.”
— Beth Willman, CEO, LSST Discovery Alliance
While Rubin Observatory’s First Look milestone reflects the work of thousands of contributors around the globe over more than two decades, it is also only the beginning. LSST’s data and opportunity for discovery are ahead of us; LSST will impact human’s understanding of the universe and the practice of how scientists pull their discoveries out big data for generations to come.
LSST Discovery Alliance is honored to help position the global science community to fully harness transformative power of LSST. Through programs in software and data tools, training and collaborative networks, we are supporting a dynamic and growing community of nearly 3,000 researchers – an estimated one-third of the world’s astronomy community – already preparing to work with LSST data. These scientists, across 31 countries, bring diverse backgrounds, career stages, and research questions to Rubin LSST — and will be among the first to unlock its transformative potential.

This image combines 678 separate images taken by NSF-DOE Vera C. Rubin Observatory in just over seven hours of observing time. Combining many images in this way clearly reveals otherwise faint or invisible details, such as the clouds of gas and dust that comprise the Trifid nebula (top right) and the Lagoon nebula, which are several thousand light-years away from Earth.

This image shows another small section of NSF-DOE Vera C. Rubin Observatory’s total view of the Virgo cluster. Visible are two prominent spiral galaxies (lower right), three merging galaxies (upper right), several groups of distant galaxies, many stars in the Milky Way galaxy and more.
