Sometimes it's hard to get the connection between what happens far away in space and things that you can touch and feel on the ground. Of course, the science of "out there" is intertwined with the science of "right here." A new module for teachers in our Chandra Education section demonstrates that perfectly.
Dr. Gisela Dreschhoff
Since the 1970s, Dr. Gisela Dreschhoff has traveled to Antarctica and Greenland to study the effects from space imprinted on deep ice cores extracted from the ground. While she was initially interested in historic energetic events from the Sun, she has also looked at her data to see if some of the most famous supernova explosions – including Kepler, Tycho, and Cassiopeia A – have also left their mark in the ice.
