SDSS-J13820-3154

SDSS J13820-3154 is a irregular galaxy located approximately 946.7 million light-years from Earth in the constellation Gemini. Its coordinates in the sky are right ascension 138.202° and declination -31.541°, and it is catalogued in the SDSS.

The light reaching Earth from SDSS J13820-3154 today left the galaxy roughly 946.7 million years ago. What you see in telescope imagery is a snapshot of the galaxy as it appeared before most of Earth’s mammalian history.

Through the Galactic Registry, you can symbolically dedicate SDSS J13820-3154 in a name, memory, or message of your choosing. Your dedication is filed permanently in our public registry and printed on an archival 12″×18″ cotton-stock certificate, shipped worldwide. This is not an official IAU renaming — only the International Astronomical Union can officially name celestial bodies — but it is a permanent symbolic act tied to a galaxy that demonstrably exists, can be pointed at from any observatory on Earth, and has been imaged by NASA, ESA, or a ground-based telescope.
