Scientists using NASA's Juno spacecraft have created an audio track of the probe's flyby of Jupiter's moon Ganymede using electromagnetic data captured during the mission.

Why it matters: This type of converted data can help scientists learn more about Jupiter's extreme magnetic field and how it interacts with the planet's largest moon.

Details: The 50-second video released last week sounds alien. (Listen.)

  • "If you listen closely, you can hear the abrupt change to higher frequencies around the midpoint of the recording, which represents entry into a different region in Ganymede's magnetosphere," Juno principal investigator Scott Bolton said in a statement.
  • The change in frequency could be due to Juno passing from Ganymede's night side to the moon's day side, William Kurth, who works on the mission said, but more analysis is needed to account for those changes.

The big picture: Juno started orbiting Jupiter in 2016, and since then, the spacecraft has been beaming back data to help researchers learn more about the massive planet.

  • Photos from Juno are helping scientists realize that storms on Jupiter look a lot like the cyclones found in Earth's oceans.
  • “When I saw the richness of the turbulence around the Jovian cyclones, with all the filaments and smaller eddies, it reminded me of the turbulence you see in the ocean around eddies,” Lia Siegelman, an oceanographer who studies this, said in the statement.
  • It's possible that by understanding Jupiter's long-lived storms, researchers may be able to figure out more about how storms on Earth also work, according to NASA.

First look: Senators propose bill to ban corporate PACs

Sens. Mark Kelly (D-Ariz.) and Jon Ossoff (D-Ga.) will soon propose a bill prohibiting for-profit corporations from establishing and managing political action committees, according to a copy of the legislation obtained by Axios.

Why it matters: The introduction of "The Ban Corporate PACs Act" comes amid heightened scrutiny on Capitol Hill regarding money in politics, including efforts to bar companies from influencing political campaigns and federal elections. It would likely face a court challenge and First Amendment concerns.

YouTube has deactivated two channels linked to the Oath Keepers militia group whose members have been charged in relation to the January 6 Capitol riot, the company told Axios.

FAA clears more planes after 5G fears

The Federal Aviation Administration said Thursday it had approved nearly 80% of the U.S. commercial fleet to perform low-visibility landings at airports with new 5G services after fears of signal interference limited 5G rollout.

Why it matters: The FAA approvals will help provide more certainty after the agency raised fears that 5G signals could reduce the accuracy of certain equipment, known as radio altimeters, that helps planes land and take off in inclement weather.
