The 2017 Gruber Foundation Cosmology Prize recognises Sandra Faber for a body of work that has helped establish many of the foundational principles underlying the modern understanding of the Universe on the largest scales.

The Gruber Foundation Cosmology Prize honours a leading cosmologist, astronomer, astrophysicist or scientific philosopher for theoretical, analytical, conceptual or observational discoveries leading to fundamental advances in our understanding of the Universe.

Less than a hundred years ago, astronomers were still debating whether our Milky Way Galaxy was the entirety of the Universe or if other galaxies existed beyond our own. Today, astronomers estimate the number of galaxies within the visible Universe at somewhere between 200 billion and 2 trillion. For more than four decades, Sandra Faber — now Professor Emerita at the University of California, Santa Cruz, and Astronomer Emerita of the University of California Observatories — has served as a pivotal figure in leading and guiding the exploration of this unimaginably vast and largely unknown scientific territory.

The citation praises Faber for “her groundbreaking studies of the structure, dynamics, and evolution of galaxies.” Her work has led to the widespread acceptance of the need to study dark matter, to an appreciation of the inextricable relationship between the presence of dark matter and the formation of galaxies, and to the recognition that black holes reside at the heart of most large galaxies. She has also made significant contributions to the innovations in telescope technology that have revolutionised modern astronomy. Through these myriad achievements, Faber has aided and inspired the work of astronomers and cosmologists worldwide.

The advances and discoveries she has been involved in, both observational and technological, have helped define how scientists think about and investigate galaxies and superclusters of galaxies, the largest structures in the Universe. For Faber, though, they have also helped define how civilisation can conceive of its place in the cosmos. In recent years she has become a prolific public speaker, delivering her lecture “Cosmic Knowledge and the Future of the Human Race” around the world.

“Astronomical knowledge is probably the most important single discipline that you need to know in order to be an informed citizen of Earth,” Faber comments. The reason, she says, is that developments in astronomy over the past few decades have shown us that we have been given “the precious gift of cosmic time” — the concept that the universe exists on a scale of billions of years and that planet Earth will be a safe haven for us for hundreds of millions of years into the future. “Astronomical knowledge tells us how we got here and furthermore, having understood that, we can extrapolate more confidently for the future.”

In addition to a cash award of $500 000, Faber will receive a gold medal and a citation that reads: “The Gruber Foundation proudly presents the 2017 Cosmology Prize to Sandra Faber for her groundbreaking studies of the structure, dynamics, and evolution of galaxies. Her research ranges from detailed studies of the stellar populations, masses, dark matter content, and supermassive black holes in nearby galaxies, to surveys of distant galaxies over cosmic time. The results of these investigations have aided and inspired the work of astronomers and cosmologists worldwide.”

Our 18th IOASA Star Catalogue is finally published and we are happy to announce that 2274 records are already written in and there are more to go. Official ceremony will be conducted on March 20th, with our partners and sponsors invited to the party.

This year IOASA continues to expand its operations in defferent countries. Last year we opened six new branches on 3 continents and this year we are planning to open more. This couldn't be achieved without generous donations from our sponsors and partners in government bodies. Our goal is to make astronomical sciences available to anyone in the world and we hope for your support to make it happen.

Thank you!
