Since 2018 the Zwicky Transient Facility, an international astronomical collaboration based at the Palomar Observatory in California, has scanned the entire sky every two to three nights. As part of this mission, the ZTFâs Bright Transient Survey has been counting and cataloguing supernovae â flashes of light in the sky that are the telltale signs of stars dying in spectacular explosions. On Dec. 4, ZTF researchers â including astronomers at the University of Washington â announced that… Read more

The Vera C. Rubin Observatory’s 8.4-meter Simonyi Survey Telescope in Chile has now been equipped with all three of its mirrors, plus a camera for good measure. James Davenport, research assistant professor of astronomy at the UW, is quoted. The UW's Željko Ivezić and Mario Jurić, both professors of astronomy, are mentioned. Featured on GeekWire

When an orca hunts salmon, it clicks and buzzes. It sends a beam of sounds from its nasal passages into the murky depths in hopes that the sound waves will bounce back and reveal the location of its next nutritious meal. Those hopes are often dashed when noise from passing vessels drowns out orcas’ sonar signals. Jennifer Tennessen, senior research scientist at the UW Center for Ecosystem Sentinels, is quoted.… Read more

Using machine learning, UW scientists managed to confirm that galaxies in denser regions of the universe can be as much as 25% larger than galaxies with a similar mass and shape in less dense regions. Aritra Ghosh, a postdoctoral researcher in astronomy at the UW, is quoted. Featured on Space 
NASAâs upcoming Nancy Grace Roman Space Telescope will look for âfossilsâ of galaxy formation by conducting high-resolution imaging studies. Through a grant from NASA, astronomers are designing a set of possible observations called RINGS â the Roman Infrared Nearby Galaxies Survey â that would collect these images, and the team is producing publicly available tools that the astronomy community can use once Roman launches and starts collecting data.… Read more

New research shows that galaxies in denser parts of the universe are usually larger than those that are more isolated. Aritra Ghosh, a postdoctoral researcher in astronomy at the UW, is quoted.Featured on Earth.com 
A new study has found galaxies with more neighbors tend to be larger than their counterparts that have a similar shape and mass, but reside in less dense environments. In a paper published Aug. 14 in the Astrophysical Journal, the team, which used a machine-learning algorithm to analyze millions of galaxies, reports that galaxies found in denser regions of the universe are as much as 25% larger than isolated galaxies. The findings resolve a long-standing debate among astrophysicists over the… Read more

This weekend, NASA said to keep your eyes peeled for the peak of the Perseid meteor shower. According to NASA, the Perseid meteor shower runs from July 14 through Sept. 1, but will peak on the night of Sunday, Aug. 11. James Davenport, research assistant professor of astronomy at the UW, is interviewed.… Read more
