WHL0137-08 - Galaxy Cluster (Attempted Observation)

WHL0137-08 (Cetus)
WHL0137-08 is a massive Galaxy Cluster that has been
reported to lense the most distant star ever seen.nicknamed 'Earendel'
Alias for WHL0137-08 :  PSZ1 G155.25-68.42
(Cluster of Galaxies Candidate) in Aladin/Simbad.

Earendel's discovery by the Hubble Space Telescope was reported
on 30 March 2022. The star was detectable due to gravitational lensing
caused by the presence of the galaxy cluster WHL0137-08 between
it and the Earth, concentrating the light from the star.

Position of WHL0137-08 (not visible) is shown by white circle
