Wisconsin science, industry play critical roles in creating powerful new Rubin Observatory
The NSF-DOE Rubin Observatory is a groundbreaking achievement for astronomers. Scientists and companies in Wisconsin made the endeavor possible.
Light from faraway galaxies can show us what the universe was like billions of years ago. But the movements and mysteries of those galaxies tell physicists that we still don’t know what makes up the vast majority of the universe.
“How did it begin? When will it end? What is it made of?”
Keith Bechtol, a physics professor at University of Wisconsin-Madison, said these are some of the questions scientists will try to address with a new observatory in Chile featuring the biggest camera ever built.
The NSF–DOE Vera C. Rubin Observatory, funded by the U.S. National Science Foundation and U.S. Department of Energy’s Office of Science, released the first set of images on June 23. The stunning images represent the fruits of a decades-long effort to push the study of the cosmos well past its current limits.
Building the Rubin Observatory, which sits on a summit in Chile’s Andes Mountain range, spanned three decades and involved parts and people from three continents. Some of the most important support came from Wisconsin.
‘Visionary’ Rubin Observatory provides detailed look at the cosmos
Beginning in October 2025, the Rubin Observatory will embark on the Legacy Survey of Space and Time (LSST). Over the next 10 years it will scan the entire Southern Hemisphere sky about 800 times, providing the most detailed look at the universe to date.
The plan going forward sounds deceptively simple.
Getting to the starting point was anything but that.
“The whole idea for the (Rubin) observatory was so visionary when it was conceived (in the 1990s) that many of the technologies didn’t exist at that time” said Bechtol.
Bechtol served as the System Verification and Validation Scientist for the international team in charge of the Rubin. He oversaw much of the testing that ensures scientists will reliably get the high-quality data they are seeking.
Observatories usually face trade-offs between how big an area they scan, the resolution of the photos they take and how fast they can take them. The scientists designing the Rubin attacked these challenges on all three fronts.
The Simonyi Survey Telescope installed uses an innovative mirror system to reflect incoming light onto a camera the size of a car. After scanning one piece of the sky, the whole system rapidly spins to look in a different direction, rotating in coordination with its protective dome while maintaining near perfect alignment of the mirrors.
According to Bechtol, displaying one image at full resolution would require enough high-definition TVs to cover a basketball court.
The final step in building the Rubin — installing the 80-ton mirror system — was made possible by the Milwaukee-based company PFlow Industries.
Pieces of the telescope were assembled at a staging area but needed to be raised five stories to be installed in the dome. PFlow custom-built a lift capable of moving critical equipment from the assembly area to the dome. A video shared by Rubin Observatory shows this lift in action.
During and after construction, Bechtol organized a series of “rehearsals” to simulate how the Rubin will operate. He accounted for details including the workflow of operating it, the challenge of transferring massive amounts of data from the summit, and even making sure the summit hotel was staffed and had food for its residents.
After nearly 30 years of dreaming, designing, building and testing, the first images from Rubin Observatory arrived.
Scientists share new images with the public
UW-Madison hosted a First Look Party on June 23 to view these images with the public. Nearly 100 people gathered in a physics department auditorium to watch a livestream of a press conference in Washington, D.C., before participating in a panel discussion with Bechtol and other scientists who will use data from the Rubin.
Even though Monday was the first chance for the public to see the images, some of the scientists involved in the project had a sneak peek.
“I woke up in bed and saw messages” that the first images had come in, said Miranda Gorsuch, a graduate student at UW-Madison who has Bechtol as an advisor. “It was like waking up from a dream.”
Gorsuch plans to use the data to study the structure of the universe and how it evolves over time.
Rubin Observatory is named after Vera C. Rubin, an astronomer who first provided observations suggesting we might not be able to see most of the matter making up the universe. Understanding the properties of this “dark matter” is one of the top priorities for scientists who will use the collected data.
But there is so much more to learn; the Rubin is already showing outer space in incredible detail. Just one small slice of our solar system imaged by Rubin Observatory already led to the discovery of 2,000 new asteroids. In one image of the full field of view, scientists detected 10 million galaxies — many for the first time. By repeatedly scanning the sky, scientists hope to use the Rubin as an alert system for rare events, like supernovae, which they can then observe in more focused follow-up studies.
“This is when science works best – when you have this interplay” between new discoveries and the new questions they raise, Bechtol said.
“There’s a science case (for building the Rubin), but any time you do this, there is also a set of questions you haven’t thought to ask yet” said Eric Wilcots, dean of the College of Letters and Science at UW-Madison.
While UW-Madison was just one of many universities involved in the international project, Wilcots believes its participation will inspire future scientists and attract them to Wisconsin.
Both Bechtol and Wilcots stressed the importance of sustained financial support from the NSF and DOE to bring the project to fruition.
Rob Morgan was one of the first graduate students advised by Bechtol, working on a Dark Energy Survey that served as a precursor to Rubin Observatory. According to Morgan, the Rubin is the culmination of the astronomy field’s shift towards a “big data” approach. Now, Morgan applies the skills he learned as an astrophysicist to his work at Google’s office in Madison.
“Google is where ‘big data’ is done for the rest of the world,” said Morgan.
This week’s image release represented a beginning. Scientists will spend years collecting and analyzing data. Still, the opening provided a moment worth cherishing.
“We don’t get a lot of observatory openings,” said Alyssa Jankowski, who recently completed an undergraduate degree at UW-Madison. “It’s important to celebrate.”

Wisconsin DNR opens 2026 elk season applications March 1, with more Central Zone tags
(WLUK) — Applications for Wisconsin’s 2026 elk season open next week.
The DNR says the application period begins Sunday, Mar 1 and will close on Sunday, May 31.
Selected applicants will be notified in early June.
For the third year in a row, there will be increased opportunity to pursue elk within the Central Elk Management Zone (formerly Black River Elk Range), as additional bull elk and antlerless harvest authorizations will be available through the state licensing system. The 2026 elk quota for the Central Elk Management Zone is six bull elk and six antlerless elk, up from a quota of four bull and five antlerless in 2025.
The Northern Elk Management Zone (formerly Clam Lake Elk Range) quota will be eight bull elk, subject to a 50% declaration by Ojibwe tribes.
During the open application period, applicants will have the choice to submit one bull elk license application and/or one antlerless elk license application, separately. Applicants can apply to any unit grouping with an associated quota for that authorization type (bull or antlerless). The order of drawing will be bull licenses first, followed by antlerless licenses. As a reminder, only one resident elk hunting license can be issued or transferred to a person in their lifetime, regardless of authorization type.
In 2026, there will be one continuous hunting season, opening Saturday, Oct. 17, and continuing through Sunday, Dec. 13, eliminating the split-season structure that was in effect from 2018-2025. This offers elk hunters more opportunities and flexibility to pursue elk in Wisconsin.
Wisconsin residents can submit elk license applications online through the Go Wild license portal or in person at a license sales agent. The application fee is $10 for each of the bull elk and antlerless elk drawings and is limited to one application per person, per authorization type. The DNR recommends that all applicants check and update their contact information to ensure contact with successful applicants.
For each application fee, $7 goes directly to elk management, monitoring and research. These funds also enhance elk habitat, which benefits elk and many other wildlife. If selected in the drawing, an elk hunting license costs $49.
Before obtaining an elk hunting license, all selected hunters must participate in a Wisconsin elk hunter education course. The class covers Wisconsin elk history, hunting regulations, biology, behavior and scouting/hunting techniques.

Winter transition will bring spring swings to Northeast Wisconsin
(WLUK) — Snow remains deep across parts of the Northwoods and the Upper Peninsula, even though much of Northeast Wisconsin has seen notable snow-melting heading toward spring.
It’s connected to a shift in Pacific climate patterns.
As of Thursday, 75.1% of the Northern Great Lakes area was covered by snow. Snow depth across the Northwoods and the U.P. ranges from 20 to 30 inches, with areas along and north of Highway 8 in Wisconsin at about 20 inches.
But farther south, significant snowmelt has occurred over the last few weeks across Northeast Wisconsin and the southern half of the state.
Looking ahead, an ENSO-neutral spring is looking likely, meaning Pacific Ocean temperatures are not notably above or below average. Conditions tend to be more normal and seasonal, though that does not guarantee typical weather.
La Niña occurs when the Pacific Ocean has below-average temperatures across the central and east-central portions of the equatorial region. El Niño is the opposite, with warmer ocean temperatures in those regions. Those shifts influence weather across the United States and globally.
In Wisconsin, a La Niña spring is usually colder and wetter, while an El Niño spring brings warmer and drier conditions. During a neutral period, neither El Niño nor La Niña is in control and weather can swing either direction.
Despite the snowpack up north, the 2026 spring outlook from Green Bay’s National Weather Service leans toward a low flood risk, because ongoing drought in parts of the state is helping to absorb snowmelt.
BE THE FIRST TO COMMENT
Dry conditions are also raising fire concerns in several parts of the country. Low snowfall in states out west is increasing wildfire concerns, and those areas are already experiencing drought. Wildfire activity can increase quickly if above-normal temperatures and below-normal precipitation continue into spring. About half of the lower 48 states are in drought this week — an increase of 16% since January.
