As autumn begins, Georgia skies become a busy highway for millions of migrating birds, heading south. Benjamin Freeman, a biologist at the Georgia Tech School of Biological Sciences, says the timeline for this fall migration period is just beginning here in the Peach State.

On July 1, the Asteroid Terrestrial-impact Last Alert System (ATLAS) detected what was first believed to be an asteroid. As calculations for its orbit progressed, it was found to be from outside our solar system, only the third interstellar object ever detected.

[One] thing that astronomers discovered early on was that, rather than being an asteroid, the interstellar interloper dubbed 3I/ATLAS was a comet.

"It is doing things that we expect comets to do. It's producing the types of gasses that we see comets produce. It's got a coma and a tail now pointed in the expected direction," said James Wray, a professor at the Georgia Institute of Technology's School of Earth and Atmospheric Sciences. "I would say the short summary is it looks generally like a comet. But in detail, there are some intriguing differences from solar system comets."

School of Biological Sciences Professor Marvin Whiteley has been named the 2026 recipient of the American Society for Microbiology's D.C. White Award for Interdisciplinary Research. This award recognizes Whiteley’s distinguished accomplishments in interdisciplinary research and mentoring in microbiology.
