An international collaboration that produced the first-ever photo of a black hole last year has been upended by the coronavirus pandemic.

Why it matters: The Event Horizon Telescope collaboration is expected to one day capture a clear photo of the black hole at the center of the Milky Way — revealing exactly what's going on in the heart of our own galaxy.

Details: The EHT uses a network of powerful radio telescopes around the world to take observations in tandem and piece together images of black holes.

  • Last year, the organization released its first photo of the black hole at the center of the galaxy M87, proving out Einstein's predictions about the nature of black holes.
  • Had all gone according to plan, the EHT was planning to send astronomers around the world this year to aid in observations using the telescopes and to bring others into the collaboration.
  • Travel restrictions and concerns about the virus forced the cancellation of those plans.
  • "We just could not ensure everyone's safety as they went to these different observatories and kept up their work," Shep Doeleman, the head of the collaboration, said during a press conference last week.

Yes, but: The collaboration is still planning to use the data they've already gathered to learn more about black holes.

  • By using the data collected in 2017, the EHT was able to see the jets shooting from the quasar 3C 279 in more detail than ever before.
  • The scientists behind the project also hope to mine the data for new discoveries in the coming months.

Louisville officer: "Breonna Taylor would be alive" if we had served no-knock warrant

Sgt. Jonathan Mattingly, the Louisville officer who led the botched police raid that caused the death of Breonna Taylor, said the No. 1 thing he wishes he had done differently is either served a "no-knock" warrant or given five to 10 seconds before entering the apartment: "Breonna Taylor would be alive, 100 percent."

Driving the news: Mattingly, who spoke to ABC News and Louisville's Courier Journal for his public interview, was shot in the leg in the initial moments of the March 13 raid. Mattingly did not face any charges after Kentucky Attorney General Daniel Cameron said he and another officer were "justified" in returning fire to protect themselves against Taylor's boyfriend.

U.S. vs. Google — the siege begins

The Justice Department fired the starter pistol on what's likely to be a years-long legal siege of Big Tech by the U.S. government when it filed a major antitrust suit Tuesday against Google.

The big picture: Once a generation, it seems, federal regulators decide to take on a dominant tech company. Two decades ago, Microsoft was the target; two decades before that, IBM.

Why the stimulus delay isn't a crisis (yet)

If the impasse between House Speaker Nancy Pelosi and the White House on a new stimulus deal is supposed to be a crisis, you wouldn't know it from the stock market, where prices continue to rise.

  • That's been in no small part because U.S. economic data has held up remarkably well in recent months thanks to the $2 trillion CARES Act and Americans' unusual ability to save during the crisis.
