NASA's James Webb Space Telescope confirms galaxy cluster XLSSC 122 at 10.4 billion light-years as the farthest strong gravitational lens. Swipe to see →
ASTROPHYSICAL PARAMETERS AND
By precisely mapping the deflection geometry of the giant blue arcs and combining them with weak lensing measurements across the outer periphery of the cluster.
DISCOVERY HIGHLIGHT
The James Webb Space Telescope has officially identified galaxy cluster XLSSC 122, located 10.4 billion light-years from Earth at a redshift of $z = 1.98$.
KEY EVIDENCE
In contemporary astrophysics, dark matter neither emits, reflects, nor absorbs electromagnetic radiation.
