NGC 2261 Hubble's Variable Nebula

The Hubble's Variable Nebula (NGC 2261) is a reflection nebula located in the constellation Monoceros. It is famous for its unique feature of changing shape and brightness over time, which is relatively rare among nebulae. The nebula is illuminated by a young star, R Monocerotis, whose surrounding protoplanetary disk of dust and gas causes the observed variations. Studying Hubble's Variable Nebula provides astronomers with valuable insights into star formation and the evolution of protoplanetary disks.

This captivating image of NGC 2261 was captured using a 0.5-meter CDK20 telescope with LRGB filters. With a total exposure time of 6.9 hours, the resulting photograph reveals the intricate details of the reflection nebula. The image showcases the beautiful interaction between the light from the young star R Monocerotis and the surrounding dust and gas, which create an ever-changing appearance. This stunning representation of the celestial phenomenon is a testament to the beauty and mystery of the cosmos.

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.
