The effect, known as the Shapiro Delay, is the extra time delay light experiences by traveling past a massive object due to general relativistic time dilation. Spinning 317 times per second, this pulsar (PSR J1614-2230) and its companion white dwarf star complete an orbit in just under nine days. The pair, some 3,000 light-years distant, are in an orbit seen almost exactly edge-on from Earth, which gives astronomers the information they need to make a mass measurement.

Connect with NRAO Tweets by TheNRAO The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc. Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media. The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progess of science; to advance the national health, prosperity, and welfare; to secure the national defense..." AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
