Google Cloud fuels new discoveries in astronomy
From understanding our origins to predicting future events, some of the greatest breakthroughs we’ve made on Earth have come from studying the universe. High-performance computing and machine learning (ML) are accelerating this kind of research at an unprecedented pace. At Google Cloud, we’re proud to play even a small role in advancing the science of astronomy—and that’s why we’re excited today to highlight new work with the Vera C. Rubin Observatory in Chile and researchers at the California Institute of Technology.
The cloud foundation for 20TB of nightly sky observations
In a pioneering collaboration, the Rubin Observatory has finalized a three-year agreement to host its Interim Data Facility (IDF) on Google Cloud. Through this collaboration, Rubin will process astronomical data collected by the observatory and make the data available to hundreds of users in the scientific community in advance of its 10-year Legacy Survey of Space and Time (LSST) project.
The LSST aims to conduct a deep survey over an enormous area of sky to create an astronomical catalog thousands of times larger than any previously compiled survey. Using the 8.4-meter Simonyi Survey Telescope and the gigapixel LSST Camera, the survey will capture about 1,000 images of the sky every night for 10 years. These high-resolution images will contain data for roughly 20 billion galaxies and a similar number of stars, providing researchers with an unparalleled resource for understanding the structure and evolution of our universe over time. By building the IDF on Google Cloud, Rubin Observatory will lay the foundation to manage a massive dataset—500 petabytes in total—that will eventually be shared with the scientific community at scale, and with flexibility.
“We’re extremely pleased to work with Google Cloud on this project, which will have a big and positive impact on our ability to deliver for the Rubin community,” says Bob Blum, acting director of operations for Rubin Observatory.
“We don’t have to build the infrastructure ourselves—it’s well-established and has been tested and improved for other users, so we benefit from that,” explains Hsin-Fang Chiang, data management science analyst and engineer for Rubin Observatory, and one of the early users of the IDF.
Caltech researcher discovers new comet with AI
While comet sightings are relatively common, the discovery of a new comet is rare. The Minor Planet Center, which tracks the solar system’s minor bodies in space, cataloged fewer than 100 new comets in 2019, as opposed to about 21,000 new minor planets.
In late August 2020, Dr. Dmitry Duev, research scientist in the Astronomy department at Caltech, began a pilot program to use Google Cloud’s tools to identify the objects observed by the Zwicky Transient Facility (ZTF) at the Palomar Observatory in Southern California. The ZTF scans the Northern skies every clear night, measuring billions of astronomical objects and registering millions of transient events. Using these images, Duev trained an ML model on Google Cloud to pinpoint comets with over 99% accuracy. On October 7, the model identified Comet C/2020 T2, the first ever such discovery attributed to artificial intelligence. This achievement makes the discovery of new comets possible at a greatly accelerated rate.
“Having a fast and accurate way to classify objects we see in the sky is revolutionizing our field,” Duev says. “It’s like having a myriad of highly trained astronomers at our disposal 24/7.”
Interested in using Google Cloud to unlock the secrets of the universe?
These are just a few of the fascinating projects we’re working on with our customers in astronomy. In April 2019, the Event Horizon Telescope, a virtual combination of eight radio telescopes from all over the world, used Google Cloud’s virtual machine (VMs) instances to produce the first image of a supermassive black hole. And, since 2018, Google has also been working in partnership with the Frontier Development Lab on applying machine learning to some of NASA’s most challenging problems in our universe: forecasting floods here on Earth, finding minerals on the moon to support a permanent base there, and predicting solar flares that can interrupt satellite communications.
