Indian Satellite AstroSat Detects Extreme Ultraviolet (UV) light from Galaxy 9.3 Billion Light-years Away!

Posted on July 26, 2021




Photek is proud to have contributed to the Indian Space Agency (ISRO) project where they have shown a new Galaxy 9.3 billion light-years away.


The Indian satellite AstroSat uses intensifiers developed and built at Photek in Hastings between 2010 and 2013. AstroSat was launched in 2015, and after a period of calibration started surveying regions of the sky of special scientific interests at different wavelengths deep into the UV spectral region (completely invisible from Earth). Additional information can be found at Contact Photek for further information for UV detectors and Scientific Space Applications.
