Sh2-188 Shrimp Nebula

SH2-188 is often called the Shrimp Nebula and sometimes even called the Dolphin Nebula. If you rotate the image 90 degrees it looks like a dolphin jumping out of water.

The expanding gas from SH2-188 has a nearly circular shape, but is much brighter to the southeast (lower left). This is because the rapidly moving central star – at about125 km/s – is creating a bow shock in that direction in the surrounding interstellar medium. Faint wisps of gas can also be seen in the opposite direction, which will eventually dissipate away. SH2-188 is considered to be one of the best examples of interaction between a planetary nebula with the interstellar medium.

Thanks, Eddie

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.
