Itai Linial, Member (2022–23); Shi-Fan Chen, Member (2022–25); and Nadine Soliman, Member (2025–30), all from the School of Natural Sciences, have received 2025 Astrophysics Postdoctoral Fellowships from NASA. The trio will join an “outstanding” class of fellows to address questions such as “How does the universe work?” and “How did we get here?”

Yue Hu, NASA Hubble Fellow in the School of Natural Sciences, has been announced as one of the recipients of the 2025 Cecilia Payne-Gaposchkin Doctoral Dissertation Award in Astrophysics. Hu's thesis was praised for opening "new ways of exploring the properties of astrophysical turbulent magnetic fields."

Chris Hamilton, John N. Bahcall Fellow in the School of Natural Sciences, has been recognized in the 2024 Early Career Collection of the Physics of Plasmas journal for his “outstanding” paper on stellar systems and kinetic theory, a prestigious accomplishment for emerging physics scholars.

This month, an effort to unite three astrophysical research communities who exploit common techniques to understand waves in gaseous disks, galaxies, and stars was made by three scholars from the School of Natural Sciences. John N. Bahcall Fellow Chris Hamilton and Members Callum W. Fairbairn and Uddipan Banik organized a workshop titled IAStrophysical Waves, at which over thirty astrophysicists from across the globe were in attendance.

Frank and Peggy Taplin Member George N. Wong, Visitor Lia Medeiros, and Professor James Stone, all from the Institute's School of Natural Sciences, have developed an innovative technique to search for black hole light echoes. Their novel method, which will make it easier for the mass and the spin of black holes to be measured, represents a major step forward, since it operates independently of many of the other ways in which scientists have probed these parameters in the past.

Why are some stars brighter than others? Why are some redder or bluer? A plot from a recent research paper by Hsiang-Chih Hwang, Member in the School of Natural Sciences, which addresses this question, has been selected as the Gaia Space Telescope's Image of the Week.

Scott Tremaine, Professor Emeritus in the School of Natural Sciences, has received an honorary doctorate from the University of Waterloo in recognition of numerous seminal contributions to the field of astrophysics, notably "establishing the theory that supermassive black holes are at the core of galaxies."

Sara Seager, Long-Term Member (1999–2002) in the School of Natural Sciences, has been announced as one of the winners of the 2024 Kavli Prize in Astrophysics. Seager was presented with the award for "ground-breaking work" on the discovery and characterization of exoplanets and their atmospheres.
