NGC 2835 ist eine Balken-Spiralgalaxie mit ausgedehnten Sternentstehungsgebieten vom Hubble-Typ SBc im Sternbild Hydra südlich der Ekliptik. Sie ist schätzungsweise 30 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 70.000 Lichtjahren.
Das Objekt wurde am 13. April 1884 von Ernst Wilhelm Leberecht Tempel entdeckt.[5]

A pretty spiral with lots of star formation going on. The blue areas show where near-ultraviolet light is more strongly emitted, indicating recent or ongoing star formation.

This spiral galaxy was observed as part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) program, a large project that includes observations from several space- and ground-based telescopes of many galaxies to help researchers study all phases of the star formation cycle, from the formation of stars within dusty gas clouds to the energy released in the process that creates the intricate structures revealed by Webb’s new images.NGC 2835 is 35 million light-years away in the constellation Hydra.Learn more about what can be seen in this vast collection of Webb images here.[Image description: Webb’s image of NGC 2835 shows a densely populated face-on spiral galaxy anchored by a central region that is bright blue. The spiral arms appear muddled, but it is possible to pick out individual spiral arms. The arms extend to the edges and rotate counterclockwise.]
