It's raining rocks on a world hundreds of light-years from Earth.

The big picture: Scientists have found more than 4,000 planets outside of our solar system, giving them a window into the wide variety of worlds that exist out there in the universe, and placing our own planet in a more full context.

What they found: A study published in the Monthly Notices of the Royal Astronomical Society uses computer simulations to reveal new details about the previously discovered planet K2-141b, which is host to winds that blow faster than the speed of sound and an ocean of lava.

  • The planet — which is about the size of Earth — also has a "rock cycle," in which vaporized rock on the extremely hot day side of the world creates a thin atmosphere over some parts of the planet that condenses and falls down as rain.
  • Temperatures on the day side of the tidally locked planet can reach about 5,432°F, with the night side hitting temperatures of -328°F.
  • “All rocky planets, including Earth, started off as molten worlds but then rapidly cooled and solidified. Lava planets give us a rare glimpse at this stage of planetary evolution,” Nicolas Cowan, one of the authors of the study, said in a statement.

New Hubble image sheds light on Neptune's storms

Neptune has never had a dedicated space mission, but the Hubble Space Telescope is still shedding new light on the workings of the mysterious planet.

Driving the news: A new photo from the space telescope shows a long-lived storm — the dark spot in the upper center — first spotted in 2018 still going strong.

Illustration: "Axios on HBO"

White House senior adviser Cedric Richmond told "Axios on HBO" that it's "doable" for President Biden to make first-term progress on breaking down barriers for people of color, while Congress studies reparations for slavery.

Why it matters: Biden said on the campaign trail that he supports creation of a commission to study and develop proposals for reparations — direct payments for African-Americans.

Cyber CEO: Next war will hit regular Americans online

Any future real-world conflict between the United States and an adversary like China or Russia will have direct impacts on regular Americans because of the risk of cyber attack, Kevin Mandia, CEO of cybersecurity company FireEye, tells "Axios on HBO."

What they're saying: "The next conflict where the gloves come off in cyber, the American citizen will be dragged into it, whether they want to be or not. Period."
