(Clarification:) This week, the Event Horizon Telescope (EHT) begins a 10-day attempt to capture the image of the supermassive black hole at the center of the Milky Way galaxy. The EHT derives its extreme magnifying power by connecting widely spaced radio dishes across the globe into an Earth-sized, virtual telescope. The National Science Foundation (NSF) has been a longtime supporter of the EHT program, which is receiving a considerable boost in sensitivity and resolution through inclusion of the NSF-funded Atacama Large Millimeter/submillimeter Array (ALMA), located in Chile, into the EHT world-wide virtual telescope. NSF Director France Córdova issued the following statement to mark the occasion:

This week heralds an exciting and challenging endeavor for astronomy. The Event Horizon Telescope will seek to capture a first-ever image of the supermassive black hole at the center of the Milky Way, our home galaxy. Radio telescopes from around the world, anchored by the ALMA observatory in Chile, will work in concert to test some of physics' most fundamental theories. Success will depend on both a vast network of observations and analysis of voluminous data. NSF has funded this ambitious project for the past decade, including providing major funding for ALMA. We are proud to support such a visionary goal.
