Indian satellite Astrosat has found a new 'ray' but it is far away from the Earth …

Pune: India's first multi-wavelength satellite-Astrosat has made an amazing discovery. AstroSat has detected the presence of extreme ultraviolet (UV) light emanating from another galaxy, which is about 9.30 billion light years away from Earth. The Inter-University Center for Astronomy and Astrophysics (IUCAA), Pune-based inter-university center for space science and space physics, gave this information on Monday.

International scientists of Pune-based IUCAA carried out this feat through Astrosat, which is considered a very important discovery. The International Team of Astronomers is led by Dr. Kanak Saha, an associate professor at IUCAA. This discovery has been told in full detail in 'Nature Astronomy' on 24 August. The discovery has been made by a team of international experts, including scientists from India, France, Switzerland, the US, Japan and the Netherlands.

Doctor Saha and his team captured this UV light through Astrosat in October 2016, and kept in touch with him for nearly 28 hours. This was researched for the next two years. Actually, this type of ultraviolet radiation (UV radiation) absorbs the Earth as soon as it enters its orbit (Earths atmosphere), in such a way that it can be detected only by a satellite positioned in space.

Explain that to accomplish this task, NASA has deployed the Hubble Space Telescope-HST, which is much larger than the AstroSat's UVIT telescope, but Astrosat's UVIT has He did what he could not do.

IUCAA director Dr Somak Rai Chaudhary said, 'This discovery is one of the most important discoveries related to the Dark Age, through which we will know the story of the birth of light. However, a lot has to be done for this. I am proud of the success of my colleagues.
