China's Five-hundred-meter Aperture Spherical radio Telescope (FAST) began official science operations earlier this month, making it the largest operating telescope of its kind on Earth.

Why it matters: The $100 million Breakthrough Listen project is expected to survey 100 nearby galaxies, 1 million stars and the galactic plane for radio signatures that could only have been sent out by an advanced society, and FAST is expected to help.

  • Scientists have trouble parsing out exactly which signals might be from outside of our solar system and which might have been created by human activity.
  • FAST's advanced technology will help cut down on any false-positives, Breakthrough Listen scientist Vishal Gajjar told Axios.

Where it stands: FAST has already done a preliminary observation in collaboration with Breakthrough Listen, listening for signals from the planet GJ273b as a proof of concept for the telescope, Gajjar said.

  • Breakthrough Listen expects to hunt for radio signatures coming from the Andromeda galaxy and planets discovered by NASA's Transiting Exoplanet Survey Satellite using FAST, Gajjar added.
  • Breakthrough Listen and FAST also have a partnership to share information, making sure any promising looking signals are followed up on quickly.

But, but, but: Just because scientists are listening for advanced intelligent life doesn't mean it's out there, or that we can hear it.

  • While powerful telescopes like FAST aid in the hunt, it's possible that our tools simply aren't sensitive enough to pick up SETI signals yet.

Scoop: Mike Bloomberg's anti-chaos theory

Mike Bloomberg's $100 million Florida blitz begins today and will continue "wall to wall" in all 10 TV markets through Election Day, advisers tell me.

Why it matters: Bloomberg thinks that Joe Biden putting away Florida is the most feasible way to head off the national chaos we could have if the outcome of Trump v. Biden remained uncertain long after Election Day.

Biden's hardline Russia reset

When he talks about Russia, Joe Biden has sounded like Ronald Reagan all summer, setting up a potential Day 1 confrontation with Russian President Vladimir Putin if Biden were to win.

Why it matters: Biden has promised a forceful response against Russia for both election interference and alleged bounty payments to target American troops in Afghanistan. But being tougher than President Trump could be the easy part. The risk is overdoing it and making diplomacy impossible.
