ALMA observes record-breaking stellar flare from Proxima Centauri

Image showing an active M dwarf star, Proxima Centuari, in red with many star spots, ejecting a large stellar flare in yellow and white. Proxima Centauri b, a small Earth-like planet is seen in the distant right of the image.

Artist’s conception of the violent stellar flare from Proxima Centauri discovered by scientists in 2019 using nine telescopes across the electromagnetic spectrum, including the Atacama Large Millimeter/submillimeter Array (ALMA). Powerful flares eject from Proxima Centauri with regularity, impacting the star’s planets almost daily.

False color image of protoplanetary disks side by side. Left is a ring disk showing blue scattered outer ring, green inner rings with gaps, and a yellow core. Center is a transition disk with a thin outer blue ring and thin green and yellow rings, and a large empty cavity in the center. Right is a compact small disk with thin blue and green rings, and a large inner yellow core with no gaps.

The National Radio Astronomy Observatory is a facility of the 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 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.
