NGC 2313

This Astrobin Debut Object is a small cometary nebula located 4000 light years away in the constellation of Monoceros at a declination of -8 degrees. The nebula spans 40 arc-seconds in our apparent view. This corresponds to a width of about 1 light year.

A cometary nebula is a reflection nebula that looks like a comet, with a head shrouded in dust and a fan-shaped tail. They often are the birthplaces of stars and they usually have young stars in their heads. The most famous example is Hubble's Variable Nebula. My collection of cometary nebulae is here.

The nuclei of cometary nebulae are usually T Tauri type variable stars. In this object, the orange variable source star is the magnitude 14.5 star V* V565 Mon.

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.
