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.
