Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

because the average person doesn't know what a torus is anymore
I don't know what a torus is. But it sure looks flat to me.
It's not. It's 2 spheres. But when you look at a diaphanous sphere straight on you can see a brighter thing through it. You can see the pink parts only at the edges because there isn't a brighter mass behind it. And the edges cause more of the material to bunch up making it easier to see.
what did you just call me
I burst out laughing
Turns out a toroid is a common shape
Always has been. 🍩
You're projecting your desires everywhere.
because simpsons did it.
This is the best summary I could come up with:
Mesmerising images of the end stages of a distant star's life have been captured by the James Webb space telescope (JWST).
They show an unprecedented level of detail of a doughnut-like structure of glowing gas known as the Ring Nebula.
Some 2,600 light-years from Earth, the nebula was born from a dying star that expelled its outer layers into space.
"We are witnessing the final chapters of a star's life, a preview of the sun's distant future so to speak, and JWST's observations have opened a new window into understanding these awe-inspiring cosmic events.
The so-called "planetary nebulae" is a misnomer that dates back to the 18th century, when the astronomer William Herschel mistook their curved shapes for those of planets.
It formed when a dying star blasted much of its substance into space, producing a variety of patterns and glowing rings and wispy clouds that seem to ripple outwards.
The original article contains 280 words, the summary contains 150 words. Saved 46%. I'm a bot and I'm open source!
RIP
Is the pictures rotated in such a away to make it look like as viewed from a specific location on earth? Or why is not just the straight picture?
They probably rotated it to align with the ICRS.
Ah thank you! One of those things that are essentials impossible to Google without prior knowledge.
Wait, what? How probable is a binary star system consisting of White Dwarfes?
Very probable.
Binary systems are very common.
Stars of the size that end their lifecycle as white dwarfs are also very common.
But considering how White Dwarfs are born, both being there without one being blown away/sucked up? Didn't know binary White Dwarfs are even possible.
