This mosaic image captures a spectacular region near the edge of the constellation Vela. The glowing bluish filaments on the right side are the "Vela Supernova Remnant", the aftermaths of a massive star blowing its gut out about 11,000 years ago. Our ancestors back then would have seen an extremely bright new star appearing in the sky, bright enough to be seen in broad daylight. The debris cloud from the death explosion drifted outward for 11,000 years, forming the complex nebula you see in this image. On the left side are RCW 3, NGC 2671 and RCW 32 (GUM15), a group of emission nebulae and star clusters.

(The original data was acquired from Telescope Live, which I processed using pixinsight and photoshop).

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.
