NGC 1300 ist eine Balken-Spiralgalaxie vom Hubble-Typ SBbc im Sternbild Eridanus am Südsternhimmel. Das Zentrum der Galaxie weist eine interessante Spiralstruktur mit einem Durchmesser von ca. einem Kiloparsec auf. Sie ist schätzungsweise 67 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 125.000 Lichtjahren. Gemeinsam mit NGC 1297, PGC 12680 und PGC 12701 bildet sie die NGC 1300-Gruppe. NGC 1300 ist Mitglied des Eridanus-Galaxienhaufens.

Das Objekt wurde am 11. Dezember 1835 von dem britischen Astronomen John Herschel entdeckt.[5]

Multiwavelength View of NGC 1300 (ALMA, VLT) (2022-007-01FRNP2ZWBJ47ECPBBBN939F3E).png
This image of spiral galaxy NGC 1300 combines multiple observations to map stellar populations and gas. Radio light observed by the Atacama Large Millimeter/submillimeter Array (ALMA), represented in yellow, highlights the clouds of cold molecular gas that provide the raw material from which stars form. Data from the Very Large Telescope’s Multi Unit Spectroscopic Explorer (MUSE) instrument is represented in red and magenta, capturing the impact of young, massive stars on their surrounding gas. Visible and ultraviolet light captured by the Hubble Space Telescope highlights dust lanes in gold and very young, hot stars in blue. High-resolution infrared images from the Webb Space Telescope will help researchers identify where stars are forming behind dust and study the earliest stages of star formation in this galaxy.

In the core of the larger spiral structure of NGC 1300, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years (1 kiloparsec) long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central black hole. NGC 1300 is not known to have an active nucleus, however, indicating either that there is no black hole, or that it is not accreting matter.

The image was constructed from exposures taken in September 2004 by the Advanced Camera for Surveys onboard Hubble in four filters. Starlight and dust are seen in blue, visible, and infrared light. Bright star clusters are highlighted in red by their associated emission from glowing hydrogen gas. Due to the galaxy's large size, two adjacent pointings of the telescope were necessary to cover the extent of the spiral arms. The galaxy lies roughly 69 million light-years away (21 megaparsecs) in the direction of the constellation Eridanus.

Now here's a dramatically long, straight bar of dust. There were other barred spirals that were expected to look something more like this, but the bar as viewed by JWST's MIRI (Mid-Infrared Instrument) showed something less organized than expected. In NGC 1300, however, the bar is about as plain to see as bars get.

Curiously, to me, anyway, the dust seems to be softer and less sharp than [this view of NGC 1566]. They were observed using the same filters (hence, resolution should not be the cause). I'm not sure what it means, if anything.

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 1300 is 69 million light-years away in the constellation Eridanus.Learn more about what can be seen in this vast collection of Webb images here.[Image description: Webb’s image of NGC 1300 shows a face-on barred spiral galaxy anchored by its central region, which is circular and shows a bright white point at the centre with a light yellow circle around it. The galaxy has a prominent bar connected to spiral orange arms that rotate counterclockwise. Together, they form a backward S shape.]
