IC 1805 Heart nebula (Emmanuel Joly)

IC 1805 Heart nebula

First panel of the IC 1805 - IC 1848 complex.The Heart Nebula, also known as IC 1805, is an emission nebula located in the constellation Cassiopeia, approximately 7,500 light-years from Earth. It is often referred to as the Heart Nebula due to its shape, which vaguely resembles a heart when observed in certain images.IC 1805 is an active star-forming region where young massive stars are born from the surrounding gas and dust. These stars emit strong ultraviolet radiation that ionizes the surrounding gas, thereby producing the characteristic bright reddish glow of emission nebulae.The Heart Nebula is often associated with an open cluster of stars known as Melotte 15, which is located at its central part. This cluster is composed of relatively young stars that formed from the same cloud of gas and dust as the nebula itself.

Premier panneau de l'ensemble IC 1805 - IC 1848.La nébuleuse du cœur, également connue sous le nom de IC 1805, est une nébuleuse en émission située dans la constellation de Cassiopée, à environ 7 500 années-lumière de la Terre. Elle est souvent appelée nébuleuse du cœur en raison de sa forme qui ressemble vaguement à un cœur lorsqu'elle est observée dans certaines images.IC 1805 est une région de formation d'étoiles active où de jeunes étoiles massives naissent à partir du gaz et de la poussière environnants. Ces étoiles émettent de fortes radiations ultraviolettes qui ionisent le gaz environnant, produisant ainsi la brillante lueur rougeâtre caractéristique des nébuleuses en émission.La nébuleuse du cœur est souvent associée à un amas ouvert d'étoiles connu sous le nom de Melotte 15, qui se trouve dans sa partie centrale. Cet amas est composé d'étoiles relativement jeunes qui se sont formées à partir du même nuage de gaz et de poussière que la nébuleuse elle-même.

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.
