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.
