AUSTRALIAN SQUARE KILOMETRE ARRAY PATHFINDER:

Australian Square Kilometre Array Pathfinder (ASKAP) is a new type of radio telescope developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
Recently, this telescope helped map around 300 million galaxies in approximately 300 hours to create a ‘new atlas of the universe.

Australian Square Kilometre Array Pathfinder

The first light of the Australian Square Kilometre Array Pathfinder was in October 2012.
The first light in Astronomy means the first use of a telescope.
The array consists of 36 identical parabolic Antennas.
The antennas work together as a single astronomical Inferometer.
Every antenna is equipped with a phased array feed.
A phased array feed creates beam of radio waves that can be electronically guided to points in different direction without moving the Antennas.
This increases the field of view of the telescope.

What is an Astronomical Inferometer?

It is an array of separate telescopes that work together as a single telescope to provide higher resolution of images of astronomical objects such as nebulous, stars and galaxies.

Evolutionary map of the universe project

The map of the universe is to be created using the telescope to make a Census of radio sources in the sky.
By tracing the radio sources the galaxies, black holes and several other Universal bodies can be detected.
