Radio “Eyes” Unlocking Secrets of Neutron-Star Collision

Posted on October 16, 2017November 16, 2017

The VLA made the first detection of radio waves coming from the neutron-star collision that generated a ripple of gravitational waves. Radio telescopes will continue to reveal new facts about this phenomenon in the coming months.

Image Release: Aging Star Blows Off Smoky Bubble

Posted on September 20, 2017September 20, 2017

Astronomers have used ALMA to image a delicate bubble of expelled material around the exotic red star U Antliae. These observations will help astronomers to better understand how stars evolve during the later stages of their lives.

Heart of an Exploded Star Observed in 3-D

Posted on July 10, 2017July 25, 2017

Deep inside the remains of an exploded star lies a twisted knot of newly minted molecules and dust. Using ALMA, astronomers mapped the location of these new molecules to create a high-resolution 3-D image of this “dust factory,” providing new insights into the relationship between a young supernova remnant and its galaxy.

Star’s Birth May Have Triggered Another Star Birth, Astronomers Say

Posted on June 20, 2017

New evidence from the VLA suggests that a jet of material ejected by a young star may have triggered the formation of a second, younger star.

Chaotically Magnetized Cloud Is No Place to Build a Star, or Is It?

Posted on June 14, 2017June 14, 2017

To make a star, the conditions inside interstellar gas clouds have to be “just right.” When it comes to a cloud’s magnetic fields, however, those conditions may range from powerful and orderly to weak and chaotic, new ALMA observations suggest.

One of Life’s Building Blocks Found around Infant Sun-like Stars

Posted on June 8, 2017June 14, 2017

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate — a chemical building block of life.

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.
