SH2-168 (Indy Backyard Astro)

SH2-168

SH2-168 is a striking nebula in the constellation Cassiopeia, about 5,200 light-years from Earth. It’s a part of the Sharpless catalog, a collection of bright nebulae that emit light due to ionized hydrogen. Often nicknamed a "star nursery," SH2-168 is a stellar birthplace where young, hot stars ignite and light up the surrounding gas.This nebula is a region filled with hydrogen gas, which glows in red and pink hues when it’s ionized (charged) by radiation from young, massive stars. This radiation strips electrons from hydrogen atoms, which later recombine, releasing energy in the form of colorful light. The main source of this illumination is thought to be an energetic B-type star, known for its intense ultraviolet radiation. This radiation "excites" the nebula, leading to the glowing effect that astronomers observe.SH2-168 lies near the more prominent Heart and Soul Nebulae and is part of the Perseus Arm of the Milky Way, one of the galaxy’s spiral arms rich in star-forming regions. Although it’s not as widely photographed as some neighboring nebulae, SH2-168’s intriguing patterns and colors attract both amateur and professional astronomers who seek to capture its beauty.Studying SH2-168 and similar nebulae helps scientists understand star formation, the life cycle of gas clouds, and the influence of massive stars on their surroundings. As these young stars evolve, they sculpt and disperse the gas, often leading to the formation of new stars. This ongoing cycle of creation within SH2-168 offers a small glimpse into the dynamic processes that shape galaxies over millions of years.

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.
