Just before the new year, a Washington University professor was among a group of scientists who launched a telescope from Antarctica that could observe bright, massive objects in space, like black holes.

The international team of researchers, which included Wash U physics professor Henric Krawczynski, wanted to collect data on black holes and neutron stars, a very dense collapsed core of a giant star.

Studying such celestial phenomena helps astrophysicists test the fundamental laws of physics, Krawczynski said.
