Using gas velocity data, scientists observing Elias 2-27 were able to directly measure the mass of the young star’s protoplanetary disk and also trace dynamical perturbations in the star system. Visible in this animation are the dust continuum 0.87mm emission data (blue), along with emissions from gases C18O (yellow) and 13CO (red).

Seen here as an ALMA (orange) composite with Hubble Space Telescope (red) data, NGC1566 was among the nearly 100 galaxies catalogued by the PHANGS survey of the nearby Universe. NGC1566 exhibits grand-design spiral plus stellar bar morphology.

While conducting a census of nearly 100 galaxies in the nearby Universe, the PHANGS survey observed NGC0628, a galaxy with pure grand-design spiral morphology. NGC0628 is shown here as an ALMA (orange) composite with Hubble Space Telescope (red) data.

During a survey of nearly 100 galaxies in the nearby Universe, the PHANGS team observed NGC1385, a galaxy featuring pure flocculent disk morphology. The survey concluded that contrary to accepted scientific theory, not all stellar nurseries look or act the same. NG1385 is shown here as an ALMA (orange) composite with Hubble Space Telescope (red) data.

Twenty galaxies in the nearby universe shown as ALMA and Hubble Space Telescope composites. They are shown in orange and red to highlight their different structures, including spirals, rings, S shapes, and more.

During the PHANGS survey of nearly 100 galaxies in the nearby Universe, the team observed NGC4321, a galaxy featuring asymmetric morphology. NG4321 is shown here as an ALMA (orange) composite with Hubble Space Telescope (red) data.

Seen here as an ALMA (orange) composite with Hubble Space Telescope (red) data, NGC3627 is one of nearly 100 galaxies observed during a PHANGS census of the nearby Universe. The census revealed that stellar nurseries within galaxies are diverse in both appearance and behavior. This thwarts commonly accepted scientific theory. NGC3627 is an example of asymmetric morphology catalogued by the study.

Shown here as an ALMA (orange) composite with Hubble Space Telescope (red) data, NGC5248 is an example of a galaxy featuring asymmetric morphology, and is one of nearly 100 galaxies catalogued by the PHANGS project during a recent census of the nearby Universe. The study revealed that stellar nurseries in galaxies are extraordinarily diverse in their appearances and behaviors, and that how they look and act depends on their location.

While conducting a census of nearly 100 galaxies in the nearby Universe, the PHANGS survey observed NGC3351, a galaxy featuring an outer ring and bar morphology. Prior to the study, scientists believed that all, or most stellar nurseries, looked and behaved the same. The study revealed that stellar nurseries are actually characterized by extraordinary diversity. NGC3351 is shown here as an ALMA (orange) composite with Hubble Space Telescope (red) data.

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.
