Since the discovery of the first exoplanet just over twenty years ago, the study of exoplanets has grown explosively. By now, astronomers have discovered thousands of exoplanets, with an incredibly diverse array of properties. This growth will undoubtedly continue into the future, as new kinds of planets are being observed with increasingly advanced telescopes. Faculty in CIERA study exoplanets theoretically and build instruments to directly image them.

The groups of Professors Rasio and Lithwick carry out theoretical work and simulations to study the long-term dynamics of planetary systems. Both groups study the chaotic dynamics of multi-planet systems as they evolve. Professor Rasio’s group also studies planet-planet interactions, star-planet interactions and tidal disruptions, and planets in binary star systems.
Professor Ulmer’s group is developing new infrared camera technology to advance our understanding of planetary systems by directly imaging planets around other stars.

Balloon-borne Large Aperture Submillimeter Telescope – The Next Generation (BLAST-TNG) BLAST is a 5,000 pound balloon-borne telescope bound for the stratosphere over Antarctica, to search for the origins of stars and planets. This photo was taken by graduate student Paul Williams in the summer of 2018 in Palestine, Texas at the Columbia Scientific Ballooning Facility.

Balloons Above Antarctica: The Coolest Place to Put a Telescope
Northwestern Physics and Astronomy student Paul Williams presents a talk as part of the Northwestern Ready Set Go (RSG) program. The goals of the program are to increase awareness for the urgent need for excellent research communicators and to coach graduate and post doctoral researchers to improve their own presentation skills. The program focuses on three important

The Late Evolution of Our Solar System
The Late Evolution of Our Solar System
This movie, Life of the Pleiades, was generated from an interactive visualization that Aaron Geller developed with Mark SubbaRao using Uniview. The interactive version can be shown on a planetarium dome, or rendered into a movie (as shown here). A 3D version of this movie exists in the Space Visualization Lab at the Adler Planetarium.
Created by A. M. Geller and M. SubbaRao, using Uniview; music, narration and audio by A. M. Geller; dynamical calculation with stellar evolution performed using the NBODY6 code.

When Worlds Collide
When Worlds Collide
“Hot Jupiters” are Jupiter-like planets with orbits close to their host star. Their origins are debated, and some young planetary system may even host multiple Hot Jupiters. Here, we investigate a planetary system of two Hot Jupiters orbiting a Sun-like star. The system is born on the edge of instability, and over time, the planets’
