Featured Video: Why Hydrogen Tells Us the Story of the Universe

Hydrogen is the most abundant element in the universe. Radio astronomers can see hydrogen by the light it emits, reflects, and even absorbs. Because hydrogen is everywhere, it can tell stories about the cosmos from the Big Bang to today.

Join our host Summer Ash of the National Radio Astronomy Observatory as she talks about how hydrogen can tell us so much about the structure and evolution of the universe.

The National Radio Astronomy Observatory is a facility of the U.S. 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 U.S. National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress 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.
