Costellazione Cefeo

Ascensione retta 22h 13m 25s [1]

vdB 152 è una nebulosa a riflessione visibile nella costellazione di Cefeo.

La sua posizione si individua circa 4° ad est di Alfirk (β Cephei), in una regione ricca di nebulose oscure e campi stellari, posta sul bordo meridionale del Cepheus Flare; al suo interno si trova una stella bianco-azzurra di sequenza principale, BD+69 1231, di magnitudine 9,29, la cui radiazione imprime ai gas circostanti un colore nettamente azzurrognolo. La stella si trova sull'estremità più meridionale di una nebulosa oscura dall'aspetto cometario, con una lunga chioma che si disperde in direzione nord. Nella parte settentrionale della nube si trova LDN 1217, una nube molto densa in cui la presenza di diverse sorgenti di radiazione infrarossa fanno pensare alla presenza di fenomeni di formazione stellare. La distanza della struttura è stimata sui 400 parsec (circa 1300 anni luce).

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.
