(17 Oct) Scientists Just Detected a Long-Lost Planet ‘Hiding’ Inside Earth
When a Mars-sized meteorite slammed into Earth billions of years ago, the impact completely reset any and all chemical processes on Earth, leaving nothing from before. Or so we thought.

"Planetary Rings" by XKCD comic (Fediverse mirrors @xkcd @xkcdbot ) - Geosynchronous Earth Orbit (GEO), where a #communications #satellite stays above a point on the surface, was theorized in 1929. It took #SciFi writer Arthur C Clarke to popularize the concept in the mid-1940s. Satellites have launched to GEO since the 1950s. They're all still there, too high for atmospheric drag. The ring around the equator is often called the Clarke Belt. https://xkcd.com/3156/ #astronomy #planetary #science

Astronomy fact: a century ago, Earth didn't have rings, but we have one now! It's where all the satellite dishes are pointed.
Title text: If you don't know where you are on Earth, the angle of satellite dishes can help constrain your latitude. If some of them are pointing straight up, you're probably near the Equator, right under the ring.
explanation:
A planetary ring is a disc of small objects and other material orbiting a planet. The most well known are the rings of Saturn, which were discovered by Galileo Galilei, but all the gas giant planets in the Solar System have rings, as do some minor planets and moons.
Earth does not have a natural ring system. It's theorized that it may have had one in the distant past. However, since the 1950's we have launched many artificial satellites into Earth orbit, and the ones in the Geostationary Orbit are in the equatorial plane, so they constitute an artificial ring system.
[...] In terms of mass, Earth's ring system is tiny compared to other planetary ring systems. [...]](https://files.mastodon.social/cache/media_attachments/files/115/391/029/858/335/808/original/de365c7c69b7af68.png)

Short story : it can be useful, but hallucinations need expert to check the facts, after reading the original material, so the usefulness for increased speed is not really there (or it is there, with great risks).

For this week's Creative Code challenge by @sableraph : " Orbits”, OrbitalMashUp envisions a solar system where the orbits aren’t quite aligned. Coded with LiveCodeLab & HydraVideoSynth with its soundtrack coded in SonicPi.
Planets Packaging
Their stars and orbits
To the other galaxies
Altering their extremities
To finalise the proximities
That they are not bounded to keep
Or seek
The orbits are the culprits
In the clashing of the galaxies
And what is it,
That they really want to be able to see

(02 Oct) ‘Failed Star’ Mimics a Key Sign of Life—and That’s Bad News for Alien Hunters
The finding suggests phosphine—a potential biosignature—shouldn’t be viewed as evidence of alien life until natural, non-biological sources are ruled out.

Planetary is a different experience every time I read it.
This time around, as just one example, I’ve realized that three pages in Planetary issue 1 had to have been the inspiration for Jonathan Hickman’s Secret Wars run-up in the two Avengers titles. Those pages could’ve come straight out of Hickman’s Avengers run except for the fact that they appeared in print a decade and a half earlier.
