PHANGS-ALMA Survey

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.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), scientists completed a census of nearly 100 galaxies in the nearby Universe, showcasing their behaviors and appearances. The scientists compared ALMA data to that of the Hubble Space Telescope, shown in composite here. The survey concluded that contrary to popular scientific opinion, stellar nurseries do not all look and act the same. In fact, as shown here, they are as different as the neighborhoods, cities, regions, and countries that make up our own world.
