New Delhi:

Astrosat, India’s first multi-wavelength astronomical observatory, on Monday accomplished 5 years of imaging celestial objects in area.

Launched by the Indian Space Research Organisation (ISRO) on September 28 2015, within the 5 years of its operation Astrosat has achieved fairly a feat.

It has carried out 1,166 observations of 800 distinctive celestial sources proposed by scientists each from India and overseas, a press release by the Department of Science and Technology (DST) mentioned.

Astrosat has explored stars, star clusters, mapping of enormous and small satellite tv for pc galaxies of the Milky Way referred to as “Magellanic Clouds”, an brisk phenomenon within the Universe such because the ultra-violet counterparts to gamma-ray bursts, supernovae, lively galactic nuclei.

“Its superior spatial resolution capability has enabled astronomers to probe star formation in galaxies as well as resolve the cores of star clusters (three times better than the last NASA mission, GALEX),” the assertion mentioned.

“Observations from UVIT has recently led to the discovery of a galaxy located at a distance of about 10 billion light-years from Earth and emitting extreme ultraviolet radiation that can ionize the intergalactic medium,” it mentioned.

Astrosat has proved to be an necessary satellite tv for pc able to finishing up simultaneous observations over a spread of wavelengths from the far ultraviolet to the laborious X-ray band.

The Ultra-Violet Imaging Telescope, or the UVIT, is a exceptional 3-in-1 imaging telescope concurrently observing the seen, the near-ultraviolet (NUV), and the far-ultraviolet (FUV) spectrum. It is likely one of the 5 payloads on board AstroSat.

Weighing a complete of of 230 kilograms, the UVIT includes two separate telescopes. One of them works within the seen (320-550 nm) and the NUV (200-300 nm). The second works solely within the FUV (130-180 nm).

The UVIT venture was led by the Indian Institute of Astrophysics (IIA), an institute of the DST in collaboration with the Inter University Centre for Astronomy and Astrophysics, Pune, the Tata Institute of Fundamental Research, Mumbai, a number of centres of ISRO and the Canadian Space Agency.

“The Ultra-Violet Imaging Telescope, which is a marvellous piece of engineering, is a testimony to the power of several scientific agencies working together in multidisciplinary mode with a shared purpose,” mentioned Ashutosh Sharma, secretary, DST.
