This image comes from a large program of observations designed to produce a treasure trove of collected observations from two large observatories: the Hubble and the Atacama Large Millimeter/submillimeter Array (ALMA), the Hubble scientists wrote. The Chilean Andes, which together are observed at wavelengths between infrared and radio waves, allow ALMA to detect clouds of cold interstellar dust that give rise to new stars.”
The combination of Hubble and ALMA observations makes the pairing fantastic for observing targets using different wavelengths, and the Hubble scientists continue: “Hubble’s extremely sharp observations at ultraviolet wavelengths allow astronomers to locate hot, narrow, and newly forming stars.
Together, ALMA and Hubble observations provide a vital data repository for astronomers studying star formation, as well as laying the foundation for future science with the NASA/ESA/CSA James Webb Space Telescope.” Like Hubble, ALMA has been used to study a variety of targets. , from things as distant as a series of planets in different stages of formation to those in our solar system like Jupiter and its complex atmosphere.
The group even contributed to large-scale projects such as the discovery of a group of massive ancient galaxies that gave clues to the early stages of the universe. NCG 4571 was imaged as part of the PHANGS-HST project (High Angle Resolution Physics in Nearby Galaxies with the Hubble Space Telescope) between Hubble and Alma.
This survey aims to learn how young stars form from gas clouds by looking at nearby galaxies, and the previous week’s Hubble image, of the beautiful spiral galaxy NCG 2835, was part of this same project.
