MACS1149-JD1

MACS1149-JD1 is a young galaxy that is known for being one of the farthest known galaxies from Earth. It was discovered in 2014 and confirmed in 2018. The JD1 galaxy is at a redshift of about z=9.11, or about away from Earth meaning that it formed when the universe was around 500 million years old.
The carbon and neon abundances of JD1 are below the solar abundance ratio. The under-abundance of carbon suggests recent star formation where a Type II supernova enriched the interstellar medium with oxygen, but intermediate mass stars have not yet enriched the ISM with carbon.
Due to a lack of old population stars detected, JD1 is probably a young galaxy.
We are able to see this galaxy because of the gravitational lensing caused by the MACS J1149.5+2223 Galaxy Cluster.
