Astronomers obtained new #JWST data on TRAPPIST-1 b, the #planet in the system closest to its #star.
New observations offer insights into how a star can affect observations of #exoplanets in the habitable zone of cool #stars.
Thwre were no signs of an atmosphere around TRAPPIST-1 b. This tells that the planet could be a bare rock, have uniform clouds or a dense atmosphere that makes it too small to detect.

Tonight: Jupiter’s major four Galilean moons Io, Europa, Ganymede and Callisto are in 1-2-3-4 order, from 19:31 Universal Time (UT) when Io swaps places with Europa, until 21:16 UT, when Io disappears in Jove’s shadow.
This event favors Europe, Africa and most of Asia. Jupiter is headed towards opposition for 2023 on November 3rd, ruling the night from sunset ‘til sunrise. The waning gibbous Moon joins the view this weekend, passing 3.1 degrees north of Jupiter Sunday night.
I’ve been finding it hard to post recently because I don’t want to get sucked in to social media being my whole life again the way it was when I was on Twitter. But of course that’s resulted in me pulling back too much and I’m trying to find the middle ground. Sorry for all the meta but this is a real struggle for me atm!

Young male college students + booze + sex = murder
Students made Oxford the murder capital of late medieval England, research suggests
https://phys.org/news/2023-09-students-oxford-capital-late-medieval.html
> A project mapping medieval England's known murder cases has now added Oxford and York to its street plan of London's 14th century slayings, and found that Oxford's student population was by far the most lethally violent of all social or professional groups in any of the three cities.
Quite a few comics and celebrities that I like still use X. At this point, it’s common knowledge how terrible Elon is, and it’s becoming inexcusable for anyone to support him or use his platform. I don’t care that it’s a way to reach the masses. The only reason that is still applicable is because “the masses” are using it to have easier access to the people who still support it. It’s a loop, and someone needs to step up and encourage boycotting it.
@zleap Nice thought! However, politicians these days exist mainly to make BigBiz happy, which means giving them more money in all kinds of "creative" ways.

Opting Out of TurnItIn
The web service TurnItIn is a "plagiarism detector". Lots of universities use it to assess whether their students are copy-n-pasting content which they haven't written.
I'm not a big fan of it. First, I'll explain how to opt-out your websites. Then I'll explain why I don't like the service.

Greenpeace warns over safety of #Zaporizhzhia nuclear plant
International regulators are incapable of properly monitoring safety at the russian-occupied the nuclear power station, according to a critical dossier compiled by #Greenpeace that is being sent to western governments on Thursday.
They conclude the IAEA has too few inspectors at Europe’s biggest nuclear plant – four – and that there are too many restrictions placed on their access.

Seeing the Web Connecting Galaxies Across the Universe
Look deeply into the Universe; the bright galaxies are the first thing you'll see. Surrounding and connecting these islands of stars is the cosmic web. These are streams of gas that flow into galaxies, supporting their star formation. Astronomers have used the new Keck Cosmic Web Imager in Hawaii to image the cosmic web, revealing the filamentary network that connects galaxies across billions of light-years of space. Previously, the web was only visible when illuminated by bright objects like nearby quasars, but this new technique can show even the faintest material.
