On Feb. 24, astronomers\u2019 computers around the world lit up with a deluge of cosmic notifications \u2014\u00a0 800,000 alerts about new asteroids in our solar system, exploding stars across the galaxy and other noteworthy changes in the night sky. The discoveries were made by the Simonyi Survey Telescope at the NSF-DOE Vera C. Rubin Observatory<\/a> in Chile and distributed globally within about two minutes.<\/p>\n

That flurry of notifications marked the commencement of the observatory\u2019s Alert Production Pipeline, a sophisticated software system developed at the University of Washington that is eventually expected to produce up to seven million alerts per night.<\/p>\n

\u201cRubin’s alert system was designed to allow anyone to identify interesting astronomical events with enough notice to rapidly obtain time-critical follow-up observations,” said Eric Bellm<\/a>, a research associate professor of astronomy at the UW who leads the Alert Production Pipeline Group for the Rubin Observatory. \u201cRubin will survey the sky at an unprecedented scale and allow us to find the most rare and unusual objects in the universe. We can\u2019t wait to see the exciting science that comes from these data.\u201d<\/p>\n

The beginning of scientific alerts is one of the last major milestones before Rubin Observatory launches its Legacy Survey of Space and Time<\/a> (LSST) later this year. During the LSST, Rubin will scan the Southern Hemisphere sky nightly for 10 years to precisely capture every visible change using the largest digital camera ever built<\/a>. These alerts will chronicle the treasure trove of scientific discoveries that Rubin will make through its time-lapse record of the universe. In the first year of the LSST, Rubin is expected to capture images of more objects than all other optical observatories combined in human history.<\/p>\n

The UW played a central role in the software that enabled this month\u2019s milestone. The alert pipeline was developed by a team of about two dozen researchers and software developers in the astronomy department\u2019s Institute for Data Intensive Research in Astrophysics & Cosmology (DiRAC)<\/a>. The team has spent the past decade working with other data management teams around the country to figure out how to process the staggering 10 terabytes of images that Rubin produces every night, and will continue to develop and operate the alert system throughout the 10-year LSST survey.<\/p>\n

\u201cEnabling real-time discovery on such a massive data stream has required years of technical innovation in image processing algorithms, databases and data orchestration. We’re thrilled to continue the UW’s legacy of excellence in data-driven science.\u201d Bellm said.<\/p>\n

While the night sky seems calm and unchanging to the casual viewer, it\u2019s actually alive with motion and transformation. Each alert signals something that has changed in the sky since Rubin last looked \u2014 a new source of light, a star that brightened or dimmed, or an object that moved. With Rubin’s alerts, scientists will have a greater ability to catch supernovae in their earliest moments, discover and track asteroids to assess potential threats to Earth and spot rare interstellar objects as they race through the solar system.<\/p>\n

Scientists can use these data to better understand the nature of dark matter, dark energy and other unknown aspects of the universe.<\/p>\n

\u201cThe discoveries reported in these alerts reflect the power of NSF-DOE Rubin Observatory as a tool for astrophysics and the importance of sustained federal support,\u201d said Kathy Turner, program manager in the High Energy Physics program in the U.S. Department of Energy\u2019s Office of Science<\/a>. \u201cRubin Observatory\u2019s groundbreaking capabilities are revealing untold astrophysical treasures and expanding scientists\u2019 access to the ever-changing cosmos.\u201d<\/p>\n

Every 40 seconds during nighttime observations, Rubin captures a new region of the sky. It then sends the data on a seconds-long journey from Chile to the U.S. Data Facility (USDF) at the SLAC National Accelerator Laboratory<\/a> in California for initial processing. Rubin\u2019s data management system automatically compares it to a template made from previous images of the same region. This comparison allows it to detect the slightest variations. With every change, such as the appearance of a new point of light, an object\u2019s movement or a change in brightness, the system generates a public alert within two minutes.<\/p>\n

\u201cThe scale and speed of the alerts are unprecedented,\u201d says Hsin-Fang Chiang, a SLAC software developer leading operations for data processing at the USDF. \u201cAfter generating hundreds of thousands of test alerts in the last few months, we are now able to say, within minutes, with each image, \u2018Here is everything. Go.\u2019\u201d<\/p>\n

Rubin\u2019s alerts are public, meaning anyone \u2014 from professional researchers to students and citizen scientists \u2014 can access and explore them. The speed of the alerts allows scientists using other ground- and space-based telescopes around the world to coordinate follow-up observations. This collaboration will enable fast and detailed studies of unfolding phenomena.\u00a0<\/p>\n

Additionally, through collaborations with platforms like Zooniverse<\/a>, Rubin will empower the global community to help classify cosmic events and contribute directly to discovery.<\/p>\n

Rubin Observatory is jointly operated by NSF NOIRLab<\/a> and SLAC.<\/p>\n
