Energetic Bullets Sent from Outer Space

It’s not just light we receive from the Universe. We receive cosmic particles on the Earth that have travelled enormous distances at incredibly high speeds. Some of these particles carry extreme energies, millions of times higher than we can achieve using man-made particle accelerators, like the Large Hadron Collider, here on Earth. Half a century after their first discovery, these cosmic rays remain mysterious. Where do they come from? Is there a smoking gun signal from their origin? How does nature manage to accelerate them to such high energies? Learn about these energetic messengers and what they can tell us about the extreme activities of the Universe.

Dr. Ke FangDr. Ke Fang obtained her doctorate in Astrophysics at University of Chicago in 2015. She was awarded NASA’s prestigious Einstein Fellowship, which brought her to Stanford in 2018 to pursue her own research program. She pieces together the information we receive from the Universe from a multitude of messengers, including high energy gamma ray radiation, ultra-light particles known as neutrinos, and cosmic rays, to study the extreme activities of the Universe.
