How Radio Astronomy Sees Magnetic Fields

Many objects in the Universe have magnetic fields. Planets such as Earth and Jupiter, the Sun and other stars,…

Astronomers Find Evidence for Most Powerful Pulsar in Distant Galaxy

Astronomers using data from the VLA Sky Survey have discovered one of the youngest known neutron stars — possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar’s powerful magnetic field emerged from behind a thick shell of debris from the explosion.

VLA Reveals Double-Helix Structure in Massive Galaxy’s Jet

Astronomers used the VLA to trace a corkscrew-shaped magnetic field in a powerful jet of material ejected from the core of a massive galaxy farther away from the central galaxy’s central black hole than ever seen before. The new images provide clues that will help understand the mechanics of such jets, which are seen throughout the Universe.

New Images Reveal Magnetic Structures Near Supermassive Black Hole

The Event Horizon Telescope (EHT) — the worldwide collaboration that produced the first image of a black hole in 2019 — has produced a new image showing details of the magnetic fields in the region closest to the supermassive black hole at the core of the galaxy M87. The new work is providing astronomers with important clues about how powerful jets of material can be produced in that region.

NRAO Contest Winners Illustrate Diverse Cosmic Phenomena

Winners in NRAO’s VLA 40th Anniversary Image Contest are from around the world, and their works illustrate a fascinating variety of celestial objects. Entries combined observational data from the VLA with data from optical, infrared, and X-ray telescopes, and from computer simulations.

IMAGE RELEASE: Magnetic Field of a Spiral Galaxy

A new image from the VLA dramatically reveals the extended magnetic field of a spiral galaxy seen edge-on from Earth.

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.
