Close-up view: Spiral Galaxy NGC 2566 in Puppis | Hubble

Featured in this NASA/European Space Agency Hubble Space Telescope picture is the spiral galaxy NGC 2566. It sits 76 million light-years away in the constellation Puppis. A prominent bar of stars stretches across the center of this galaxy, and spiral arms emerge from each end of the bar. Because NGC 2566 appears tilted from our perspective, its disc takes on an almond shape, giving the galaxy the appearance of a cosmic eye.

As NGC 2566 gazes at us, astronomers gaze right back, using Hubble to survey the galaxy’s star clusters and star-forming regions. The Hubble data are especially valuable for studying stars that are just a few million years old; these stars are bright at the ultraviolet and visible wavelengths to which Hubble is sensitive. Using these data, researchers will measure the ages of NGC 2566’s stars, helping to piece together the timeline of the galaxy’s star formation and the exchange of gas between star-forming clouds and stars themselves.

Several other astronomical observatories have examined NGC 2566, including the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope. The Webb data complement this Hubble image, adding a view of NGC 2566’s warm, glowing dust to Hubble’s stellar portrait. At the long-wavelength end of the electromagnetic spectrum, NGC 2566 has also been observed by the Atacama Large Millimeter/submillimeter Array (ALMA). ALMA is a network of 66 radio telescopes that work together as one to capture detailed images of the clouds of gas in which stars form. Together, Hubble, Webb and ALMA provide an overview of the formation, lives and deaths of stars in galaxies across the Universe.

Image Description: An oval-shaped spiral galaxy. Its core is a compact, glowing blue spot. A bright bar of light, lined with dark reddish dust, extends horizontally to the edge of the disc. A spiral arm emerges from each end of the bar and follows the edge of the disc, lined with blue and red glowing patches of stars, to the opposite end and a little off the galaxy. Blue stars are scattered between us and the galaxy.
