Artist’s impression of Planet Nine, depicted as a dark sphere with the Milky Way in the background. Neptune’s orbit is shown as a small ellipse around the Sun. The sky view and appearance are based on the conjectures of Planet Nine’s co-proposer, Mike Brown (Image: Tom Ruen).
The search for Planet 9, 10, and beyond
Planetary scientists and cosmologists at Penn work together to find planets that might be hiding in the far reaches of the solar system.

Answering big questions by studying small particles
Using electronics designed at Penn, particle physicists study neutrinos, incredibly small and nearly massless subatomic particles, to understand the fundamental nature of the universe.
STEM legacies: Five researchers reflect on the women who inspire them
For Women’s History Month, Penn faculty share their perspectives on enterprising women in STEM who have been sources of inspiration in a field with a large gender imbalance.
Willman (center) and a group of undergraduates, including physics majors as well as students studying other STEM-related disciplines, chatted informally over breakfast about their personal experiences as STEM students and researchers.
Women in Physics Group inspires the next generation of physicists and astronomers
Students had the opportunity to interact with a world-renowned astronomer during a day of informal get-togethers, networking events, and physics lectures at the annual conference.
Bacterial population growth rate linked to how individual cells control their size
Developed at Penn, a theoretical model from a new area of research at the interface of math, physics, and biology describes how individual parameters can influence population-level dynamics.
A Q&A with statistician Shane Jensen, who discusses the math behind sports team rankings, why March Madness has so many underdog victories, and how technology might change how analysts study sports teams in the future.
Penn’s Bridge to Ph.D. program provides students from underrepresented backgrounds the opportunity to earn master’s degrees in mathematics while also preparing for a Ph.D. The students are advised by Ryan Hynd (not pictured) and Philip Gressman (center).
Bridge to Ph.D. program provides a way forward for greater access in STEM fields
The pilot program in the Department of Mathematics enables students from underrepresented groups to become the next generation of enterprising mathematicians.
