NGC 6914 is the blue reflection nebula at the center of the picture. The red cloud is an extensive emission nebula, which, in part, is ionized by a group of young stars, the Cygnus OB2 association. Cygnus OB2 is an “OB association” that is home to some very young, and most massive and most luminous stars known. It also includes one of the largest known stars, NML Cygni. The region is embedded within a wider region of star formation known as Cygnus X, which is one of the most luminous objects in the sky at radio wavelengths. The region is approximately 1,400 parsecs from Earth.

The young star cluster is one of the largest known and the largest in the northern hemisphere. Although the associated nebula is over ten times more massive than the Orion Nebula, which is easily seen with the naked eye, Cygnus OB2 is hidden behind a massive dust cloud known as the Cygnus Rift, which obscures many of the stars in it. This means that despite its large size, it is hard to determine its actual properties. The estimated number of massive stars range from 50 to 100.

The Cygnus Rift, aka Northern Coalsack, is a dark, background-obscuring cloud that is similar to the dark equatorial clouds seen in many edge-on galaxies. Parts of it can be seen in the left part of, and below the blue cloud in, this image. The estimated cloud size is about 1 million solar masses.

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.
