I get questions occasionally on how images can be submitted for consideration as an Astronomy Picture of the Day. Here’s how:
- Post the image on Starship Asterisk, the discussion forum for APOD by following these instructions.
- Send links to the pictures if the image is already on the web (in a Flicker account, for example) to Drs. Bonnell and Nemiroff
- Send the images as email attachments to Drs. Bonnell and Nemiroff
Please note the text at the bottom of the About APOD page regarding submissions and uses of the image.
For posting, please keep images under 400K; posting a link to a larger image is helpful. For emailing, though larger images can be sent, sending an image under 2M is helpful; if you have the image in a larger size and can make it available, please say so in your email.
Though Drs. Nemiroff and Bonnell write the texts for APOD themselves, please let them know what they are seeing when you send your image. If there are interesting details about the image or the circumstances under which it was taken, they welcome reading them.
Please note that submitting an image does not guarantee that it will appear as an APOD; many images are submitted, far more than can possibly appear on APOD. Fewer than 1 in 10 submitted images becomes an APOD. Posting images on Starship Asterisk is encouraged so others have the opportunity to see the many fine images that are submitted even if they do not become APODs.
I hope this helps! If you need more information, please let me know in the comments. Thanks!
