One of the most distant galaxies: JADES-GS-z14-0
The galaxy is surprisingly large and bright for its young age – and the ALMA radio telescope has already found oxygen in it. So stars must have formed even earlier than was thought.
Key figures
- Light travel time
- about 13.5 billion years
- Back then
- just under 300 million years after the Big Bang
- Distance today
- about 34 billion light-years
- Discovered
- 2024 with the James Webb Space Telescope
- Constellation
- Fornax (southern sky)
Interesting facts
- It no longer holds the record alone: in 2025 Webb found MoM-z14, a galaxy whose light has been travelling a little longer still. The hunt goes on.
How do you measure something like that?
The expansion of space has stretched the galaxy's light to about 15 times its length. Originally ultraviolet, it now arrives as infrared – exactly what the James Webb Space Telescope was built for. From the redshift, astronomers work out how long the light has been travelling.
Where is it?
One of the most distant galaxies: JADES-GS-z14-0 belongs to the “The observable universe” level of the Cosmic Zoom (field of view about 93 billion light-years). As far as we can see at all. Light needs time – looking into the distance means looking into the past. At the edge glows the oldest light, from 380,000 years after the Big Bang. Right in the middle, invisibly small, is where we are.
