NGC 3718 - 3729 (PGU (Giuliano Pinazzi))

NGC 3718 - 3729

Questa sorprendente galassia NGC 3718, circa al centro dell'immagine è chiaramente una galassia a spirale distorta. I deboli bracci a spirale di NGC 3718 appaiono contorti ed estesi, la sua brillante regione centrale è attraversata da bande di polvere oscura. Sulla sinistra, distante a soli 150 mila anni luce, si osserva un'altra galassia, NGC 3729. Le due sono probabilmente in reciproca interazione gravitazionale, testimoniata proprio dall'aspetto peculiare di NGC 3718. Proprio al di sotto di sotto questa coppia di galassie distante 52 milioni di anni luce si può anche notare il notevole ammasso Hickson Group 56. Hickson Group 56 è formato da 5 galassie interagenti e dista oltre 400 milioni di anni luce. [fonte: APOD]

This striking galaxy NGC 3718, near picture center, is clearly a warped spiral galaxy. NGC 3718's faint spiral arms look twisted and extended, its bright central region crossed by obscuring dust lanes. A mere 150 thousand light-years to the right is another large spiral galaxy, NGC 3729. The two are likely interacting gravitationally, accounting for the peculiar appearance of NGC 3718. While this galaxy pair lies about 52 million light-years away, the remarkable Hickson Group 56 can also be seen clustered just below NGC 3718. Hickson Group 56 consists of five interacting galaxies and lies over 400 million light-years away. [credit: APOD]

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.
