A telescope in Chile has found a world 640 light-years from Earth that rains liquid iron, adding to the strange tapestry of planets far from our own.

Why it matters: The more that scientists understand about planets circling other stars, the closer they get to finding out just how unique (or common) our solar system — and therefore life — is.

Details: The world, named WASP-76b, is tidally locked to its star, like the Moon is to Earth. The planet’s day side gets so hot that iron evaporates into its atmosphere.

  • Winds blow strong enough on the planet that the iron moves from the day side to the night side of the world where it then cools.
  • As the atmospheric iron cools, it rains onto the cooler night side.
  • The new discovery was made using the ESPRESSO instrument on the Very Large Telescope in Chile.

The big picture: WASP-76b is only one of the many weird exoplanets — planets circling other stars — that are fascinating scientists today.

  • The planet HD 189733b has winds that blow up to 5,400 mph and likely rains glass.
  • Another world, HD 209458b, orbits so close to its star that its thick atmosphere is evaporating and the planet appears to have a tail like a comet stretching out behind it.
  • 55 Cancri e — located about 41 light-years away — is masked by a thick atmosphere that may hide a surface covered entirely in lava.

The bottom line: While many scientists are hunting for another Earth light-years away from our solar system, hundreds of other planets with their own properties are still worthy of study.

Dominion sends cease and desist letter to My Pillow CEO Mike Lindell

Dominion Voting Systems on Monday sent a cease and desist letter to My Pillow CEO Mike Lindell over his spread of misinformation related to the 2020 election.

Why it matters: Trump and several of his allies have pushed false conspiracy theories about the company, leading Dominion to take legal action. It's suing pro-Trump lawyer Sidney Powell for defamation and $1.3 billion in damages, and a Dominion employee has sued Trump himself, OANN and Newsmax.

Episode 5: The secret CIA plan

Beginning on election night 2020 and continuing through his final days in office, Donald Trump unraveled and dragged America with him, to the point that his followers sacked the U.S. Capitol with two weeks left in his term. This Axios series takes you inside the collapse of a president.

Episode 5: Trump vs. Gina — The president becomes increasingly rash and devises a plan to tamper with the nation's intelligence command.

In his final weeks in office, after losing the election to Joe Biden, President Donald Trump embarked on a vengeful exit strategy that included a hasty and ill-thought-out plan to jam up CIA Director Gina Haspel by firing her top deputy and replacing him with a protege of Republican Congressman Devin Nunes.
