ARP 273 (David Lopez Flores)

ARP 273

Aunque los detalles no están claros, parece haber una batalla titánica en curso. La galaxia superior se llama UGC 1810 por sí misma, pero junto con sus compañeras de colisión se conoce como Arp 273. La forma de UGC 1810, en particular su anillo exterior azul, es probablemente el resultado de violentas interacciones gravitatorias. El color azul del anillo exterior se debe a estrellas masivas que son muy calientes y se han formado hace solo unos pocos millones de años. La parte interior de la galaxia superior, que es una galaxia espiral más antigua, aparece más roja y con polvo filamentoso. Algunas estrellas brillantes aparecen en primer plano, sin relación con las galaxias en colisión, mientras que varias galaxias lejanas se ven en el fondo. Arp 273 se encuentra a unos 300 millones de años luz de distancia en la constelación de Andrómeda. Es muy probable que UGC 1810 devore a sus vecinas galácticas en el próximo billón de años y se convierta en una galaxia espiral clásica. Pero lo increíble de esta imagen, es haber sido captada con una cámara QHY178m que normalmente se usa para imágenes planetarias o como cámara guía. Si, se puede!!!

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.
