SDSS-J21408-2615

SDSS J21408-2615 is a elliptical galaxy located approximately 1,677.4 million light-years from Earth in the constellation Corona Borealis. Its coordinates in the sky are right ascension 214.086° and declination -26.155°, and it is catalogued in the SDSS.

The light reaching Earth from SDSS J21408-2615 today left the galaxy roughly 1,677.4 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 J21408-2615 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.
