GBT Reveals Satellite of Milky Way in Retrograde Orbit

Posted on May 22, 2003April 4, 2017

New observations with National Science Foundation’s Green Bank Telescope suggest that what was once believed to be an intergalactic cloud of unknown distance and significance, is actually a previously unrecognized satellite galaxy of the Milky Way orbiting backward around the Galactic center.

Giant Cosmic Lens Reveals Secrets of Distant Galaxy

Posted on April 3, 2003November 25, 2019

An international team of astronomers has discovered that a young galaxy had a central disk of gas in which hundreds of new stars were being born every year — at a time when the Universe was only a fraction of its current age.

Surprising Image Revises Understanding Of Dwarf Galaxies

Posted on January 8, 2003April 4, 2017

An intensive study of a neighboring dwarf galaxy has surprised astronomers by showing that most of its molecular gas — the raw material for new stars — is scattered among clumps in the galaxy’s outskirts, not near its center as they expected.

Giant Radio Jet Coming From Wrong Kind of Galaxy

Posted on January 8, 2003April 4, 2017

Giant jets of subatomic particles moving at nearly the speed of light have been found coming from thousands of galaxies across the Universe, but always from elliptical galaxies or galaxies in the process of merging — until now.

Clouds Dominate the Galactic Halo

Posted on January 7, 2003April 4, 2017

Using the exquisite sensitivity of the National Science Foundation’s Green Bank Telescope, astronomer Jay Lockman of the National Radio Astronomy Observatory in Green Bank, West Virginia, has produced the best cross-section ever of the Milky Way Galaxy’s diffuse halo of hydrogen gas.

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.
