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.

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.

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 relationship between a galaxyâs size and its environment, but also raise new questions about how galaxies form and evolve over billions of years.

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.

Beginning next year, the Vera C. Rubin Observatory will use the world’s largest digital camera to give us a whole new view of the universe. Mario Jurić, professor of astronomy at the UW, is quoted.

The 2023-24 Honors Excellence in Teaching Award goes to Dr. Oliver Fraser, assistant teaching professor in the Department of Astronomy.

Despite problems with humanity’s use of carbon-based fossil fuels, our whole existence is based on this element’s ability to create rich chemistry. Don Brownlee, professor of astronomy at the UW, is mentioned.

With the help of Google Cloud, scientists churned through hundreds of thousands of images of the night sky to reveal that the solar system is filled with unseen objects. Željko Ivezić, professor of astronomy at the UW, is quoted.

At a recent workshop, researchers and journalists debated how to announce a potential discovery of extraterrestrial life. Victoria Meadows, professor of astronomy at the UW, is quoted.

Seattle’s cloudy weather made for an anticlimactic viewing of Monday’s solar eclipse. Still, that didn’t stop dozens of people who flocked to the UW’s Physics-Astronomy Building, hoping for the clouds to lift, so they could catch a glimpse of this once-in-a-generation event. The UW's Oliver Fraser, assistant teaching professor in astronomy, and Giovanni Gollotti, a student, are quoted.

Despite the weather conditions, the courtyard of the UW Astronomy Department was busy with people trying to catch a glimpse of the partial eclipse. The Department of Astronomy hosted a viewing event with telescopes and eclipse glasses. The UW's Oliver Fraser, assistant teaching professor in astronomy, and Ruby Heidgerken, a student, are quoted.

Scientists have completed the construction of the world’s biggest camera after two decades of work for the Rubin Observatory in Chile. Željko Ivezić, professor of astronomy at the UW, is quoted.

Eclipses past and present arenât just opportunities for incredible sights. Generations of researchers have used them to study phenomena ranging from the sun itself to the fabric of the universe. UW News intervewed Emily Levesque, author and associate professor of astronomy, about what scientists past and present have learned by studying eclipses.
