JILA astrophysicists investigate a broad range of topics including the evolution of stars, the formation of planets, the dynamics of black holes, and even the fundamental properties that give rise to the Universe itself.
JILA’s astrophysics research is aided by data gathered by ground- and space-based instruments. Our researchers use this astronomical data to test and refine theoretical simulations of processes that occur in our solar system and throughout the Universe.

Recent Highlights in Astrophysics

Of the many different objects in the solar system, M-dwarf stars, also known as red dwarf stars, are of particular interest to astrophysicists. These small objects are the most common type of star in the universe and have unique properties. “If you lay out all of the different types of stars [in a plot of stellar color versus brightness] we can…

An international team of astrophysicists, including scientists from CU Boulder, may have pinpointed the cause of that shift. The magnetic field lines threading through the black hole appear to have flipped upside down,…

When it comes to inspiring young people to pursue a career within the sciences, you can't start too early. At least, that's what the JILA Excellence in Diversity and Inclusivity (JEDI) group believed when they collaborated with the Colorado non-profit organization Pretty Brainy to develop a speaker series. The series, designed for girls from…
