France has officially joined the international consortium that will build the Square Kilometre Array Observatory (SKAO), proposed to be the world’s largest radio telescope. The announcement was made by French President Emmanuel Macron. With this, France has become the first non-founding country to join the SKA consortium. The founding member-nations are Australia, South Africa, the United Kingdom, Italy, Netherlands, Portugal and China.

  2. The proposal in this regard is presently under review, after which India will announce its share of funding grant for SKA and officially join the consortium. A decision is expected by the end of 2021.
  3. Some of the other participating countries are Canada, Germany, Japan, South Korea, Spain, Sweden and Switzerland.
  4. For the project, there will be 197 dishes, each measuring 15 metres in diameter, placed in South Africa’s Karoo region.
