NGC7129 Rich stellar nests

Ngc7129, located in the constellation Cepheus, is a reflection nebula about 3300 light-years away from the earth.

The nebula is illuminated by an open cluster of newborn stars, which is thought to have more than 130 stars less than a million years old. The range shown in the above photo is about 35 light-years.

These newborn stars are also shrouded in the gas and dust of ngc7129, indicating that the star babies are very young and less than a million years old. Our sun was very similar to what it looks like five billion years ago. It was also born in a stellar incubator like ngc7129.

In this high-definition photo, the most striking is the beautiful light blue gas dust cloud, reflecting the light of the surrounding newborn stars.

The small, dense, red crescent shaped nebulae in this image are called Herbig harrow objects.

Its shape and color is a unique phenomenon produced by the jet of high-temperature material produced by newborn stars along the polar axis. This phenomenon is short-lived and will not last for more than thousands of years. When the gas continues to spray into interstellar space, the Herbig harrow object will gradually disappear.

The white flocculent and red ribbon emission nebula on the background of the light blue reflection nebula are the glow excited by the ultraviolet radiation of the surrounding stars.

The nebula will eventually be dispersed by the stellar winds emitted by its stars, leaving only an open cluster. The open star cluster will gradually disperse as it moves around the center of the Milky way.

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.
