Something is amiss in the Butterfly Nebula. When a team led by astronomers at the University of Washington compared two exposures of this planetary nebula that had been taken by the Hubble Space Telescope in 2009 and 2020, they saw dramatic changes in the material within its "wings." As the team will report on Jan. 12 at the 241^st meeting of the American Astronomical Society in Seattle, powerful winds are apparently driving complex alterations of material within the Butterfly Nebula, behavior not seen in planetary nebulae to date. The researchers want to understand how such activity is possible from what should be a “sputtering, largely moribund star with no remaining fuel.

On Jan. 11 at the 241st meeting of the American Astronomical Society in Seattle, a team led by scientists at the University of Washington and the Center for Computational Astrophysics reported something unexpected about the distinct populations of stars that make up the Triangulum galaxy: In this satellite galaxy, a close companion of the much larger Andromeda galaxy, old and new stars occur in separate parts of the galaxy's structure, something not seen in galaxies like our own and so far not reporter for other satellite galaxies.

University of Washington astronomers were on the lookout for “stars behaving strangely” when an automated alert from pointed them to Gaia17bpp, a star that had gradually brightened over a 2 1/2-year period. But follow-up analyses indicated that Gaia17bpp wasn’t changing. Instead, the star is likely part of a rare type of binary system. Its apparent brightening was the end of a years-long eclipse by an unusual, "dusty" stellar companion.

Climate change will reshape ecosystems through two types of events: short-term, extreme events — or “pulses” — and long-term changes, or “presses.” Understanding the effects of presses and pulses is essential as conservationists and policymakers try to preserve ecosystems and safeguard biodiversity. Researchers at the University of Washington have discovered how different presses and pulses impacted Magellanic penguins — a migratory marine predator — over nearly four decades and found that, though individual presses and pulses impacted penguins in a variety of ways, both were equally important for the future survival of the penguin population. They also found that these types of climate changes, taken together, are leading to an overall population decline at their historically largest breeding site.

The College of Engineering and the College of Arts & Sciences researchers are helping to establish the UW as a global leader of the coming quantum age.

Katy Pearce, an associate professor in the Department of Communication at the University of Washington (UW), is dedicated to advancing research in the field of social and political uses of technology, while also supporting students and colleagues. With a focus on digital divides and inequalities and the use of information and communication technologies for marginalized people and social movements in non-democratic states, Pearce is passionate about bridging the gap between the theoretical and lived experiences of people around the world.

"Americans spend more than half a billion dollars annually on 150 million units of imported Christmas lights. U.S. News & World Report ranks the best Christmas light displays. And ABC’s reality TV show “The Great Christmas Light Fight” recently premiered its 10th season. Christmas lights, in short, are not only ubiquitous but also central to American culture. But that has not always been the case. The man credited with popularizing Christmas lights in the early 20th century, Albert Sadacca, had never celebrated Christmas. In fact, he was a Jew from the Muslim world," writes Devin Naar, associate professor of history and Jewish studies at the UW.
