Heart nebula and Perseid meteor

Link: https://flic.kr/p/xoLjtS

Heart Nebula (IC 1805 and IC 1848) are two nebulae in the constellation Cassiopeia at 7500 light years away. Ionization source are the stars of young open cluster Melotte 15 (image center) located inside and have formed therein. These stars ionize the hydrogen and make the nebula shine with reddish light. One of them, the HD15570 is considered one of the more massive and bright stars of the entire Milky Way with a light 3 million times that of our Sun and about 100 times more massive. At the top we see a Perseid meteor pointed directly at the radiant, a little higher in the constellation Perseus, which is very close.

La nebulosa corazón (IC 1805 e IC 1848) son dos nebulosas en la constelación de Casiopea a 7500 años luz de distancia. Su fuente de ionización son las estrellas del joven cúmulo abierto Melotte 15 (centro de la imagen) situadas en su interior y que se han formado en ella. Estas estrellas ionizan el hidrógeno de la nebulosa y hacen que brille con luz rojiza. Una de ellas , la HD15570 es considerada una de las estrellas más masivas y luminosas de toda la Vía Láctea con una luminosidad 3 millones de veces la de nuestro Sol y unas 100 veces más masiva. En la parte superior vemos una perseida apuntando directamente al radiante, un poco más arriba en la constelación de Perseo que está muy cerca.

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.
