Take a Look at India’s ASTROSAT rare Discovery

I have already created an image in another direction and identified a few galaxies in this image. Soon, we will have many more.
― Prof. Kanak Saha

The Universe ages around 13.787±0.020 billion years old! For everyone, it is a subject of endless amazement. At the same time, Astronomers have been working round the clock. Their prime focus: Reveal its expansion, acceleration, and related theories.

Recently, a team of astronomers investigated a galaxy. The location of this galaxy lies is not so distant from Earth. In addition, The intelligence for the study was provided by Astrosat. This Made in India satellite telescope is a huge contribution to astronomy.

What Actually An Astrosat is?

Firstly, Astrostat is a (satellite) monitoring center stationed in space. Secondly, Its distinctive feature which allows the coverage of the full range of wavelength. Thirdly, Astrosat particularly studies black holes, the system of the galaxies, and neutron stars.

It was established in its orbit by ISRO.

Previously, Indian astronomers had to face huge challenges. They were dependent on foreign resources for data supply. With Astrosat’s arrival, we have become self-reliant.

Above all, Astrosat may not be the top of its class, but surely a jack of all trades.

Prof. Kanak Saha from IUCAA, Pune headed this research. Furthermore, The team comprised of various other astronomers. They were from universities of Switzerland, the USA, Japan, France, the Netherlands, and Tezpur University, Assam. Further, The Indo- French Centre financially supported it. This progressive step was made to promote Advanced Research.

One such telescope, UVIT (Ultraviolet Imaging Telescope) is placed within the space observatory. It collects photons with wavelengths in the ultraviolet part of the electromagnetic spectrum. Thus, the UVIT data proved handy to study the galaxies that could emit radiation in these wavelengths.

Moreover, UVIT has an upper hand over NASA’s swift (ultraviolet telescope). It can detect far shorter wavelengths of photons. These wavelengths are termed EUV or extreme ultraviolet wavelengths. The youngest stars in the galaxy produce ionizing radiations i.e. photons.

“It is the first example of a galaxy leaking extreme ultraviolet photons in that distance,” reveals Prof. Kanak Saha

The astronomers aimed the galaxy that lies at a distance of 9.3 billion light-years. The result of its images was amazing. Supposedly, EUV radiation was spotted. Formerly, any galaxy located between 4 to 11 billion light-years hadn’t been marked with EUV radiation.

Later on, the spectrum of the radiation was studied broadly. Researchers found numerous hot and young stars residing in this galaxy. In comparison to other stars (like our sun), these stars were gigantic and lived for a shorter span.

This galaxy is notably quite young with respect to astronomical standards,. The age of this galaxy is only about 0.1 billion years! In terms of mass, it is a thousand times lighter than The Milky Way.

More galaxies are waiting in line and asking for exposure. The essential data required is already compiled by Astrosat.

In fact, the work is going at considerable rate.
