Title: How far can the Square Kilometre Array see?
Post by: alfa015 on 15/11/2019 23:06:32

As some of you probably know, the Square Kilometre Array will become the biggest radio telescope on Earth, with a collecting area of 1 square kilometre.

The construction will start in 2021 and the first light is expected to take place in 2027. It will cover the frequencies from 50 MHz to 15 Ghz.

But what I wanted to share with you guys is a new study about how far the SKA can 'listen'.

A recent study points out that the SKA could detect extraterrestrial airport radars 200 light years away.

What do you guys think?

An interesting interview about the SKA, with UWA astronomer Peter Quinn (https://www.thenakedscientists.com/articles/interviews/seeing-farther-ever-square-kilometre-array), pertinent to this thread.
