This winter warrior made the gravitational waves discovery possible
Engineer Steffen Richter played an important role in the recent gravitational waves discovery, wintering at the Amundsen-Scott research station at the South Pole and making daily treks to keep the BICEP2 telescope running.

Cosmic question mark
Two ways of measuring the universe’s expansion rate disagree by about 10 percent. One of the methods may be flawed. Or it could be that a hitherto unobserved phenomenon is at work.
