As per reports, NASA’s Hubble Space Telescope (HST), which is larger than the UVIT, was unable to detect UV emission from...
...this galaxy as the signals were too faint.
AstroSat managed to identify it successfully since the background noise in the UVIT detector is comparatively lower than the HST.

The research paper states, “One of the outstanding problems of current observational cosmology is to understand the nature of sources that produced the bulk of the ionizing radiation after the Cosmic Dark Age.

As per reports, this is the first time a galaxy has been observed in the extreme ultraviolet light & will further help to shed light on the conditions of the early universe.
