Different line-of-sight velocities of the molecular gas around LL Pegasi

Visualizing the ALMA image cube of LL Pegasi

Visualizing the ALMA image cube of LL Pegasi. Each frame of the video shows the molecular gas material surrounding LL Pegasi for a different line-of-sight velocity. This velocity, advancing 1 km/s per frame, is given at the top-right corner. The field size is 20,000 times the distance between the Sun and the Earth.

Supernova 1987A: Remnants of an Exploded Star

Astronomer Remy Indebetouw talks about the star that exploded in 1987, and how the world’s telescopes have been watching the explosion ever since.

The Birth of Supernova 1987A: animation depicting the buildup and aftermath of supernova 1987A

This scientific visualization illustrates the evolution of Supernova 1987A from the initial swelling of the host star and supernova explosion to the expanding shock wave and the formation of molecules detected by ALMA in the remnant.

ALMA Discovers Unexpected Trove of Star-forming Gas in Phoenix Cluster

Video explaining the complex relationship between a supermassive black hole and its host galaxy in the Phoenix Cluster, as studied with ALMA. Jets from the black hole create giant radio bubbles. Hugging these bubbles are filaments of cold, dense gas that could eventually fuel future star formation and feed the galaxy’s active supermassive black hole.

Artist’s conception of region near the supermassive black hole inside the radio galaxy known as 3C 120, where twisted magnetic fields propel and shape jets of particles.

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.
