An interstellar comet spotted earlier this year is on its way to its close approach to the Sun this month, giving astronomers a close-up view of the visitor from outside our solar system.

What's happening: A new photo taken by Yale astronomers shows Comet 2l/Borisov's 100,000-mile-long tail and 1-mile-across nucleus in new detail.

Details: Astronomers are keeping a close eye on the comet in order to learn all they can about the composition of the interstellar object before it leaves our solar system in the coming months.

  • Images of the comet can help scientists learn about its chemical makeup and how similar or different it is to our own solar system.
  • So far, scientists have found that the comet appears to look quite similar to those found in our solar system, but as the interstellar visitor gets even closer, telescopes should be able to take more images, revealing not-yet-seen details about the object.

The Biden administration has put on hold two big arms deals with Saudi Arabia and the United Arab Emirates which were approved in the final weeks of the Trump administration, a State Department official told Axios.

Why it matters: The sales of F-35 jets and attack drones to the UAE and a large supply of munitions to Saudi Arabia will be paused pending a review. That signals a major policy shift from the Trump era, and may herald sharp tensions with both Gulf countries.

The FBI believes California Gov. Gavin Newsom (D) and the Bay Area headquarters of Twitter and Facebook were targets of a man facing federal explosives charges, according to a criminal complaint.

Driving the news: Prosecutors charged Ian Benjamin Rogers after finding weapons including five pipe bombs, 49 guns and thousands of rounds of ammunition following a Jan. 15 search of his Napa County home and auto repair business. His alleged goal was to ensure former President Trump remained in office.

Infectious disease expert Anthony Fauci highlighted the need to address racial disparities in the COVID-19 vaccination process, per an interview with The New England Journal of Medicine on Wednesday.

What he’s saying: "I think that's the one thing we really got to be careful of. We don't want in the beginning ... most of the people who are getting it are otherwise, well, middle-class white people."
