PRATUSH Telescope - SCI & TECH

News: India’s PRATUSH among telescopes astronomers want to put on, around the moon

 

What's in the news?

       Astronomers are anticipating the opportunity to unveil a new perspective on the universe by deploying high-resolution telescopes on the moon and in orbit around it.

 

PRATUSH Telescope:

       PRATUSH (Probing ReionizATion of the Universe using Signals from Hydrogen) is a radio telescope designed to be situated on the moon's far side.

 

Development:

       The telescope is being constructed by the Raman Research Institute (RRI) in Bengaluru, with active collaboration from the Indian Space Research Organisation (ISRO).

 

Deployment:

       Initially, ISRO will position PRATUSH into orbit around the Earth.

       Following adjustments and fine-tuning, the space agency will subsequently launch it towards the moon.

 

Aim:

       It aims to detect signals emitted by the first stars and galaxies, unveiling the cosmic dawn of the universe.

       It seeks to address questions regarding the timing of the first stars' formation, the characteristics of these early stars, and the nature of the light they emitted.

 

Equipment:

       The telescope will be equipped with a wideband frequency-independent antenna, a self-calibrating analog receiver, and a digital correlator.

       These instruments are designed to capture radio noise within the crucial signal originating from the Dark Ages.

 

Significance:

       PRATUSH is targeted to achieve instrument sensitivity at the level of a few millikelvin, without being constrained by any systematic features.
