A couple of well-placed satellites in orbit above Earth could capture an incredibly detailed photo of the black hole at the center of our galaxy, scientists say in a new study in the journal Astronomy & Astrophysics.

Why it matters: If scientists can capture better photos of black holes, they might be able to push Einstein’s theory of general relativity closer to its limits.

Details: The proposed Event Horizon Imager would include 2 or 3 radio telescope satellites orbiting Earth that would be able to take photos of the Milky Way's black hole — called Sagittarius A* (pronounced "A-star").

  • These satellites wouldn't need to contend with the distortion caused by gases and other components of Earth's atmosphere, allowing scientists to capture clearer images.
  • "We would be able to take images with a resolution more than five times what is possible with the EHT," Freek Roelofs, co-author of the new study, said in a statement.

The backdrop: The Event Horizon Telescope (EHT) recently delivered humanity’s first photo of a black hole — the one at the center of the M87 galaxy.

The intrigue: While the black hole imaged by the EHT looked pretty much exactly as expected, if researchers are able to get a more detailed view of one of these objects, they might see something they weren’t anticipating.

  • "If small deviations from Einstein's theory occur, we should be able to see them," study co-author Heino Falcke said in the statement.

Biden pushes unity message in new TV wave

A fresh Joe Biden ad, "New Start," signals an effort by his campaign to make unity a central theme, underscoring a new passage in his stump speech that says he won't be a president just for Democrats but for all Americans.

What he's saying: The ad — which began Friday night, and is a follow-up to "Fresh Start" — draws from a Biden speech earlier in the week in Manitowoc, Wisconsin:

Trump prepares to announce Amy Coney Barrett as Supreme Court replacement

President Trump is preparing to nominate federal appeals court Judge Amy Coney Barrett of Indiana, a favorite of both the social conservative base and Republican elected officials, to succeed Justice Ruth Bader Ginsburg, Republican sources tell Axios.

Why it matters: Barrett would push the already conservative court further and harder to the right, for decades to come, on the most important issues in American politics — from abortion to the limits of presidential power. If confirmed, she would give conservatives a 6-3 majority on the high court.
