'ALMA radio telescope shut down due to COVID-19'

The Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, the world's largest multi-dish radio telescope, has temporarily closed operations due to the spread of COVID-19 in the country, the observatory said.

ALMA shut down its operations on March 22 due to the developments related to coronavirus, according to a statement.

"We made the unprecedented decision to shut down ALMA for the well-being and health of all staff, to ensure they can be at home with their families while this pandemic unfolds," ALMA Director, Sean Dougherty said.

"An incredible effort was made by staff to ensure a safe and successful shutdown," Dougherty said.

He added that "a team continues working at the observatory to keep vital telescope systems operational and ensure that we are ready to restart operations whenever that is feasible."
