NGC 2903 es una galaxia espiral similar a nuestra propia galaxia la Vía Láctea. Las similitudes incluyen su tamaño general y una barra central. En cualquier caso, una diferencia notable es la aparición de misteriosas manchas calientes en el núcleo de NGC 2903. Al inspeccionar la imagen superior e imágenes similares obtenidas por el Telescopio Espacial Hubble, se encontró que estas manchas calientes eran brillantes cúmulos globulares jóvenes, en contraste con los uniformemente antiguos cúmulos globulares encontrados en nuestra galaxia la Vía Láctea. Investigaciones posteriores han indicado que la actual formación de estrellas está más descontrolada en un anillo alrededor del núcleo de 2000 años luz de ancho que rodea el centro de NGC 2903. Los astrónomos postulan que la gravedad de la barra central acelera la formación de estrellas en este anillo. NGC 2903 yace aproximadamente a 25 millones de años luz de distancia y es visible con un pequeño telescopio en dirección a la constelación de Leo.

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.
