Ce bel objet est un vestige de supernova situé à 5000 années-lumière dans la constellation des Gémeaux. La nébuleuse des méduses, surnommée à juste titre, s'étend sur environ 70 années-lumière et sa taille apparente est le double de celle de notre pleine lune. Cette image montre les fronts d'hydrogène, d'oxygène et de soufre gazeux restants de la violente explosion. Les restes de l'étoile à neutrons désormais dense à l'origine de l'explosion sont situés au centre de l'image.

If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.
Please note: You are on a Free account, and when you delete an image, your upload counter does not decrease (unless the image is deleted within 24 hours of uploading it). The Free account is not a way to keep your most recent or best 10 images on AstroBin, but a trial period for you to decide whether or not a paid subscription is worth it. For more information, please click here.
The image will be permanently deleted and cannot be recovered. All its revisions will be deleted too. Are you sure?
You will delete all other revisions (if any), and the originally uploaded image, leaving the current revision as the final and only version of this image.
You will delete all revisions, leaving the originally uploaded image as the final and only version of this image.
