The Dark Energy Spectroscopic Instrument (DESI) project, represented by Daniel Eisenstein, has been awarded the 2026 Lancelot M. Berkeley–New York Community Trust Prize for Meritorious Work in Astronomy. The Harvard Astronomy Department published this exciting news, highlighting the significant contributions of the DESI project to the field of astronomy. The award, which includes a $20,000 prize, recognizes the remarkable work done in this project, which aims to create a 3D map of the universe on an unprecedented scale.
Daniel Eisenstein, a Professor of Astronomy at Harvard University, is a principal investigator for the DESI project. His work focuses on large scale cosmic structures and the use of galaxy clustering for cosmological information. Eisenstein’s notable contributions to the field include his use of baryon acoustic oscillations (BAOs) as a standard ruler for length scale in cosmology. His leadership in the DESI project has made significant strides in our understanding of the universe’s structure and composition.
The DESI project, currently under operation at the Kitt Peak National Observatory in Arizona, is an international collaboration involving over 500 researchers from 75 institutions in 13 countries. The project utilizes a robotic array of 5000 fibre-optic “eyes” to capture the light from distant galaxies, quasars, and supernovae. Its goal is to map 35 million galaxies and 2.4 million quasars, covering a volume of the universe 10 times larger than any previous survey.
This comprehensive mapping will provide valuable insights into the nature of dark energy, a mysterious force believed to be responsible for the acceleration of the universe’s expansion. Eisenstein and his team aim to use this data to better understand the properties of dark energy and its role in the universe’s evolution.
The Lancelot M. Berkeley–New York Community Trust Prize is awarded annually by the American Astronomical Society (AAS) to recognize outstanding contributions to astronomy research. The prize is named after the late Lancelot M. Berkeley, a New York philanthropist and amateur astronomer. The prize will be officially awarded at the 239th AAS meeting in January 2026. As part of the award, Eisenstein will deliver a plenary address summarizing the achievements of the DESI project.
This recognition of the DESI project’s work is a testament to the importance of international collaboration in advancing our understanding of the universe. The award not only celebrates the hard work and dedication of Eisenstein and his team but also highlights the significant impact of their research on the field of cosmology. Through the DESI project, we can hope to gain a better understanding of the universe’s mysteries, including the enigmatic dark energy.
