eran_morad, in Astronomers discover six planets orbiting a nearby sun-like star

Way to bury the lede. What’s remarkable here is that the orbits are resonant.

saying they identified irregular polygonal wedges located at a depth of about 35 meters all along the robot’s journey.

So like a spaceship graveyard from the Great Star War of 4990 BC?

DigitalTraveler42,

More like cave systems or even continental outlines most likely.

isn’t any shape a geometrical shape? title could have been “China’s Mars Lander Detects Subsurface Thingy”

StealThisComment, in Enormous planet discovered around tiny star could break our understanding of solar system formation

You’re telling me they discovered an “ultra-cool dwarf star” and didn’t immediately name it Dinklage?

Tease, had me thinking they’d found a Type II civilization.

Discworld is real! Need better resolution to see Atuin and the elephants.

Aw shucks, for ‘disc’ I read ‘planet’. And ‘Large Magellanic Cloud’ is a close neighbor. But hey, it’s a start.

FTFY: Every planet in our solar system explained at a 5th grade level by probably ChatGPT.

thessnake03,

Our solar system is home to eight planets:

Mercury Mars Uranus Venus Jupiter Neptune Earth Saturn

Only a psycho would order it like that

cyberpunk007, in Every planet in our solar system explained

Ah yes. I learned Venus is earths future.

“The atmosphere is extreme due to the greenhouse effect which filled the planet with carbon dioxide.”

XeroxCool, (edited ) in One of the brightest stars in the sky will 'blink out' on Dec. 12. Here's how to watch.

8:17pm EST Dec 11, 2023

the occultation will be visible only from a narrow path stretching from Asia to southern Europe, Florida and eastern Mexico.

The article has links to maps, a detailed info page, and a livestream

Edit: bad fleshbot. I’m kinda guessing the article changes time for the reader because it absolutely says 11th, not the 12th as the title says.

But, in EST and similar time zones, it’s December 11, not 12, right? The headline says 12th; the article says Monday the 11th. And based on a different article I previously read, I set myself a calendar reminder for the 11th, so I’m leaning that way. Maybe they meant the 12th UTC?

Edit: Yep, in EST and other Western TZs, I’m reading the 11th–Monday night.

skyandtelescope.org/…/asteroid-will-cover-betelge…

Around 1:17 UTC (8:17 p.m. EST December 11th), the main-belt asteroid 319 Leona…

earthsky.org/…/betelgeuse-will-dim-disappear-aste…

So, for example, in Cordoba, Spain, the mid-point of the event will be at about 1:15:45 UTC, or 2:15:45 a.m. local time, on December 12, 2023. And in Miami, Florida, the mid-point of the event will be at about 8:24:54 p.m. local time on December 11, 2023. That’s the same as 1:24:54 UTC on December 12, 2023. Find the exact timing for your location here.

XeroxCool,

You are absolutely correct. I wonder if the title is UTC but the article adapts to the reader. I hope I don’t cause people to miss it

Thank you for untangling this. I’m calling up my science loving nieces to watch it for me and report.

XeroxCool,

Please note it’s Dec 11 EST. You may have seen my old comment that said the title’s 12th EST. So it’s best to follow the direct pages linked in the article for your timezone

lolcatnip, (edited ) in One of the brightest stars in the sky will 'blink out' on Dec. 12. Here's how to watch.

A very, very tiny total eclipse.

XeroxCool,

Things like this make you realize eclipse as a bit of an arbitrary term to cover what we feel isn’t quite a transit and isn’t quite an occultation. Total solar eclipses are occultations and annulars are transits. Lunar eclipses are very disproportionately occultations but we’re sitting inside the cozy Earth looking out like office gophers commenting “it’s really coming down now” about snow flurries. When the Martian rover saw Phobos in front of the sun, it was a transit.

Maeve, in One of the brightest stars in the sky will 'blink out' on Dec. 12. Here's how to watch.

A birthday gift for December born, a Christmas gift for everyone else!
