A little context before liftoff
Your NASA birthday picture, explained.
How do I find the NASA picture on my birthday?
Choose Birthday, enter your month, day and birth year, then select “Make my free card.” Cosmic Post finds the image published on that date in NASA’s Astronomy Picture of the Day (APOD) archive, or shows a clearly labeled alternative when the exact entry is unavailable.
Was the image taken on my date?
The date matches publication in NASA’s Astronomy Picture of the Day archive. The image may have been captured earlier; it does not show the local sky over your birthplace.
What if my year isn’t available?
APOD began in June 1995. For an earlier birthday or a missing entry, we use the closest available year for the same calendar date. If that calendar date has no match, we show another archive entry. Your card keeps your meaningful date and the actual APOD publication date.
Can I download it for free?
Yes. Add a name and save a PNG, or share the image from a supported device. No account needed. Cosmic Post is independent and is not affiliated with or endorsed by NASA.
Can I personalize my space birthday card?
Add an optional name and choose one of three greetings. Your saved PNG includes your name, greeting, meaningful date, APOD publication date and image credits. You can save the finished card or share the image from a supported device.
What if my NASA birthday picture is a video?
Some APOD video entries have a still image you can use for a card. If yours has no still, choose one of the offered image alternatives. You can still watch the original video, and the selected image keeps its actual APOD publication date on your card.
Can I make an anniversary or milestone card?
Yes. Choose Anniversary or Milestone and enter the date you want to remember. Add a name, choose a greeting and download a free cosmic card for your anniversary, a new beginning or another meaningful moment.
Can I combine my family’s NASA birthday pictures?
Yes. Use the family birthday collage to bring together names and full birthdays for two to eight people. When an image comes from another year, the collage preserves both the birthday and the APOD publication date. Save or share the finished collage as an image.
Is Cosmic Post the same project as Luminary?
Yes. The earlier project was called Luminary and used bapod.vercel.app. Its current name and home are Cosmic Post at cosmicpost.lol. Cosmic Post is independent of NASA. Individual cards now download as 1080 × 1350 PNGs.
