SpARCS1049+56 is a galaxy cluster whose heart is bursting with new stars and located at a distance of about 9.8 billion light-years away from Earth. It was discovered by NASA's Hubble and Spitzer space telescopes on 2015.[1] The galaxy cluster has a redshift of 1.7[2] and a mass of (3.5±1.2)×1014 M☉ [3] estimated from weak gravitational lensing.
