Hubble fans, rejoice. After more than a month with its camera eye closed, the famed Hubble Space Telescope is snapping photos of the cosmos once more. Julianne Dalcanton, professor of astronomy at the UW, is quoted.

Twenty scientists and engineers at the University of Washington are among the 38 new members elected to the Washington State Academy of Sciences for 2021. New members were chosen for “their outstanding record of scientific and technical achievement, and their willingness to work on behalf of the Academy to bring the best available science to bear on issues within the state of Washington.”

University of Washington Provost Mark A. Richards today announced Dianne Harris will become dean of the College of Arts & Sciences, beginning Sept. 1.

When Emily Levesque, associate professor of astronomy at the UW, was 2 years old, Halley’s Comet made its most recent close pass to Earth. Her older brother was observing the phenomenon for a school project and the whole family headed out to the backyard. Fussy, cold and afraid of the dark, young Levesque’s mood changed when her parents directed her attention to the night sky. From there she was hooked.

We may finally know why one of the brightest stars in the sky appeared to become 65% less bright than usual, in an event that astronomers have dubbed the Great Dimming. The star Betelgeuse, which marks the right shoulder of the constellation Orion, rapidly dimmed in late 2019 and early 2020. It now seems this was due to both a cool spot on the star itself and a cloud of dust. Emily Levesque, associate professor of astronomy at the UW, is quoted.

New images from a massive telescope in Chile have helped solve the mystery of why red supergiant star Betelgeuse suddenly dimmed in late 2019. Emily Levesque, associate professor of astronomy at the UW, is referenced.

“By mid-February 2020, the star [Betelgeuse] had plummeted to about 35% of its typical brightness before swiftly recovering over the next few months. The event captivated professional and amateur stargazers alike because such rapid and visible changes in the night sky are rare. Now, a year after Betelgeuse’s recovery from what has become known as its Great Dimming, Montargès et al. present a detailed picture of and compelling explanation for this strange behavior,” writes Emily Levesque, associate professor of astronomy at the UW.
