NGC 4945

New image loaded to remove slight yellow colour cast.

NGC 4945 is one of many peculiar galaxies that populate Centaurus. This remarkable spiral galaxy is seen almost edge-on, and the spiral structure is chaotic and difficult to discern. In part this is because the galaxy is itself extremely dusty, and is seen through dust in the Milky Way. These effects together account for its yellowish hue. The dust in NGC 4945 absorbs most of the visible light, especially the blue light from the numerous bright stars known to be present within the galaxy. This energy is re-radiated at infrared wavelengths, which penetrate dust more readily, which is why the galaxy is found to be unusually bright in the infrared.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
