Large Magellanic Cloud in Narrowband (OIII-Ha-S2)

The Large Magellanic Cloud in a rarely used colour mapping palette of OHS = RGB.

The narrowband data does a wonderful job of accentuating the knotted accumulations of hydrogen, oxygen and sulphur gas that form the flocculent nebula.

This small satellite galaxy in our cosmic backyard has a mass (in different models) of 30-130 billion solar masses, a weight much less than the 1.2-1.9 trillion solar mass estimate for the Milky Way which it orbits.

Recent very high velocity measurements suggest the LMC and the SMC (both satellite galaxies) are making just their first orbit of the Milky Way after being gravitationally captured. However, already there is significant interaction between these 3 neighboring galaxies. The existence of the Magellanic Stream, a tidal tail of gas that has been stripped from the SMC/LMC system and now extends half way around the Milky Way, provides further evidence for interactions between these three galaxies.

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.
