The Jellyfish Nebula (URSAMO)

The Jellyfish Nebula

The amazing jellyfish nebula in just 5hrs of data!

Photometric colour analysis:

With the color channels reassigned to the correct emission lines, we have the following normalized intensity histograms:

The blue line represents the H-alpha emission, which is typically associated with regions of hydrogen gas ionized by nearby star formation.
The red line represents the OIII emission, often found in the shocked gas of supernova remnants.
The green line represents the SII emission, which is common in areas with strong stellar winds or supernova remnant

Here we have the original image of the Jellyfish Nebula (IC 443) next to the result of a morphological analysis using edge detection. The edge detection filter highlights the boundaries within the nebula's structure, enhancing the intricate filamentary patterns and different regions within the nebula.This visualization helps in identifying the complex morphology of the nebula and can be particularly useful for studies that focus on the shapes and structures formed by various astrophysical processes. The contrasting colors on the right image indicate the various edges detected in different emission lines, with each color representing a different element or ionization state (H-alpha, OIII, and SII).

The explosion that created the Jellyfish Nebula, also known by its official name IC 443, may have also formed a peculiar object located on the southern edge of the remnant, called CXOU J061705.3+222127, or J0617 for short, likely a rapidly spinning neutron star, or pulsar.

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.
