The Vela Molecular Ridge (RCW27, RCW32, and RCW33)

The Vela Molecular Ridge is a series of HII regions that run along the northern edge of the Vela Supernova Remnant. This eight-panel mosaic taken from Chile captures nearly five degrees vertically. The image here is 1/4th the full-size image, which is 382 megapixels in size! This image was a collaboration over two months with Charles Pevsner, Max Whitby, and Raymond Protière.

RCW27 is at upper left, RCW32 in the middle, and RCW33 at bottom right. Part of the Vela SNR can be seen at upper right. The small reflection nebula embedded in RCW27 is NGC2626. The bright spot at lower-right is Kohoutek 2-15, an HII region miscategorized as a planetary nebula. There are several real planetary nebulae visible as well: Wray 16-23 is at upper left, and Wray 16-32 is at bottom left. (There are others, but they are nearly stellar in size.

The slightly odd magenta and red hues on the right are due to the unusual mixture of ionized gases in the Vela SNR. You don’t normally get SII signal without H-alpha like that outside of SNRs or planetary nebulae.

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.
