Their input source selection in the Sco-Cen region, showing stars with (blue) and without (orange) disks.

The fraction of young stars with disks as a function of age, based on three different selection methods. All show that many stars appear to have disks to ages well beyond ~10 million years, with a median lifetime of ~5 million years!

New paper led by Fabian Polnitzcky & with @sratzenboeck.bsky.social + @joaoalves.bsky.social: based on the ages of stars with infrared excess in Sco-Cen, it seems planet-forming disks last around twice as long as previous estimates suggest - giving twice as long for planets to form. 🔭☄️ #exoplanets

Who wants a medieval story time on the first autobiographer in English? She preached and led pilgrimages, but mostly she was known for weeping really loudly and publicly and making churchmen uncomfortable. Oh, she also had 14 kids and left them and her husband to go traveling (super popular choice).

Oh god no. I didn't realize it got this. We already have a mental health crisis in young ppl. We don't need this as well.

It's a comet, folks. An extrasolar comet, which makes it very cool and nothing to be afraid of.

Schweiz: Palantir-Software hat verheerende Risiken Nach Risikoprüfung des Einsatzes von Palantir-Software in der Schweiz bekam der US-Konzern eine Absage, trotz jahrelanger Hofierung von Behörden und Armee. Den Eidgenossen sind die Risiken zu groß. Da...

"Die Militärexperten (in der Schweiz) kommen zu dem Schluss, dass ein Abfluss von Daten aus den Palantir-Systemen technisch nicht verhindert werden könne."

Hmm. Das ist ja komisch. Denn die polizeilichen Palantir-Nutzer in Deutschland behaupten steif & fest das sei technisch ja gar nicht möglich. 🤔

A re-enactment of English Longbowmen at the Battle of Agincourt, with the words "All I Want For Christmas Is Yew" at the bottom of the picture. You see, my dear alt-text readers, Yew wood was the preferred wood for longbows, prized for its strength and flexibility. So it would make sense that the bowmen might want yew for Christmas. This is a pun, a terrible Christmas pun, playing off that Mariah Carey song, you know the once, yes you do. I'm a bad person for making this pun. I am so sorry.

It's a longshot people will get this joke

For the first time this century, child deaths under age 5 will likely rise. Why? A dramatic drop in mortality for youngsters under age 5 has been one of the great accomplishments in global health. But estimates suggest that in 2025 child deaths will go up.

It took the vision and commitment of the richest man in the world to finally kill more poor children and babies again.

YouTube video by Farm to Taber Answering Hank Green's Food Science Questions: Exploding Churro Edition

There was this exploding churro video going around a while back. It had some weird food science stuff going on in it that I don't think anyone has talked about yet, so here it is!

oh cripes, THREAD. (hides eyes) 🤨

Steuerdumping: Werden wir zu Gehilfen der neuen Plutokratie? Grosse Techunternehmen wie Google, Meta oder Palantir siedeln sich in der Schweiz an. Sie zahlen keine Steuern, profitieren aber von ETH-Absolventen und staatlich finanzierten Supercomputern.

«Sie sind alle hier, weil ihre Unternehmen hier keine Steuern zahlen. … Weil wir kaum Techregulierung haben. Weil wir einen der schnellsten Supercomputer der Welt haben: ‹Alps›, von der ETH mit Steuergeldern entwickelt, um KI-Modelle wissenschaftlich zu prüfen.» www.tagesanzeiger.ch/palantir-in-...

Es gibt übrigens keinen Grund zu glauben, dass auf Dauer nur Abschiebehäftlinge keinen Anspruch auf eine*n Pflichtanwält*in mehr haben. Wie die Bezahlkarte wird sich das ausweiten. Und wieder werden einige furchtbar erstaunt tun, wenn es passiert.

And now, the official statement from his excellency the Ambassodor…

Ich habe die Aussage des Essays anhand von "Es ist ein Ros entsprungen" überprüft, und was soll ich sagen: Das letzte Wort des Liedes ist "Tod".

Es wirkt so, als ob wir in Europa noch nicht so recht begriffen haben, was die von der US-Regierung #Trump veröffentlichte „Nationale Sicherheitsstrategie“ anstrebt: Unterm Strich wird eine totale Umwälzung der politischen Verhältnisse in der #EU befürwortet zugunsten von rechtsextremen Kräften.

My dad abhors any negative comments about immigrants. Asked him recently why he’s so strong on it: ‘Because we’re always happy to take the rich and clever ones. Which means it’s not about disliking immigrants. It’s about disliking the poor and vulnerable. And that’s a bad human instinct.’

TBF at the beginning world war I, too many ppl also believed it would be a walk in the park. So they were eager to fight.

Nothing good came out of this.

Wow, congrats

Once a star like the Sun runs out of hydrogen, it cools down and expands to become red giant. In the Sun’s case this will happen in about five billion years and scientists think this expansion will cause the destruction of Mercury, Venus and perhaps Earth, but lack evidence on how or whether this will definitely happen.

We knew it was going to be bad, but now we know how bad:

A study of half a million stars shows that their planets rapidly vanish as the stars grow old and bloated. The planets may get shredded, evaporated, or (most likely) dragged by tides into a fiery death. 🧪🔭

LOL. As a former Belgian I can relate.

But I really do miss Samoerei sauce. Ah well, i'll mix mayo and thai spicy red sauce. That should be close enough.

"Is Putin about to go to war with Europe?" - this is not a knock on the journalists or the publication itself (it's a good discussion), it is just that he has already been at war with Europe for years. And I fear that his successors will continue this war too. www.theguardian.com/world/video/...

This happens when magnetic field lines of opposite polarity touch: reconnection, sudden release of energy, solar flare, plasma eruption

We see a strong M6.0 flare from small region 4300 in the eastern part of the sun. The coronal mass ejection will likely miss earth.

Also, see this for an older take... 😏
