Revenant of the Swan

Near the centerline of Cygnus (the Swan) constellation lies the familiar Crescent NGC 6888. Below and to the left in this view is a variable star 34 Cygni (or P Cygni) also known as the Revenant of the Swan.

The star is an irregular variable and has, over the past 500 years, shown major brightening. Because of its variability and extreme outbursts in the 17th century, the star was thought to be a recurring nova. Presumably it was named the 'Revenant of the Swan' because it exhibited a repeated and unexpected return to life after multiple deaths or novae. (Credit Jodrell Plank Observatory). It lies about 6000 light years from Earth.

It is a class B2 supergiant between 500,000-900,000 time the Sun's luminosity. It is one of the most luminous stars in our galaxy. P Cygni belongs to a rare group of starts called "luminous blue variables". Eruptions of blue variables include ejection of vast amounts of matter. It is surrounded by a faint blue nebula created by the past 900 years of eruptions and mass loss. It will eventually become a supernova or hypernova.

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.
