I posted about spacecraft knots in 2012! Well, I edited a post by knot tyer David Fred:

Illustration of a Voyager probe in deep space. The spacecraft features a large antenna dish and several other antennas and instrument platforms extending from its central body almost like the legs and antennas of an insect.

Nearly half a century and 16 billion miles later...

From NASA: To conserve power, engineers at JPL have turned off an instrument on Voyager 1 – but the science continues!

Doesn't look like my ALT text worked, but here's the caption: Compare Hubble’s two observations of a portion of the Trifid Nebula, one taken in 2026 with the telescope’s current Wide Field Camera 3 and the other in 1997 with an earlier instrument

Did you see the comparison images showing the jet's motion??

Tim Cook donated $1M to Trump’s inauguration.

He fawned over Trump and gifted him a 24-karat gold plaque (as Apple lobbied for tariff exemptions).

Apple donated to Trump’s White House ballroom.

And it removed ICE tracking apps from its stores following a demand from the DOJ.

Remember this.

Seems like she's not the only one drinking on the job. Is it only a problem when women do it? What do you think, Kash? What do you think, Whiskey Pete?

We don't know which Cabinet secretary will be forced to resign next, but we know it'll be either Brooke Rollins or Linda McMahon because they're the last two women left.

Rubin bags 11,000 new asteroids! This is just the beginning, too. There are more millions more out there waiting to be seen.

The Vera Rubin observatory has already discovered 11,000 *previously unknown* asteroids... and the proper observing sessions haven't even begun yet!

Before launch did try to partner with the NHL for outreach and they were so excited! Then they found out we weren’t going to pay them and they couldn’t hang up fast enough. Lol. We did end up doing some nice videos with the U.S. figure skating team.

Two hooded figures with lamps approach a moonlit, isolated cottage.
A woman answers the door.
We have come for the child, says the hooded figure
So soon? she asks
It is time, says the hooded figure.
The woman is distraught. We should never have got him a library card!
What is done cannot be undone, says the hooded figure
We couldn’t see the harm! We just wanted him to enjoy reading! 
For most, it ends there, says the hooded figure, turning away and walking into the wilderness
Oh lord, What have I done! says the woman,
the child walks past her and out into the darkness with them.
Do not cry mother. 
I am a writer now.

One of the Sandy Hook families lives in hiding 1500 mi away from their baby’s grave due to people stalking them.

The graves of multiple children have been defaced.

One of the fathers had to submit DNA evidence to prove his son was a REAL HUMAN BEING after Alex Jones’ book said he never existed.

The only way this could be better is if they have live video of Alex Jones’ head exploding upon hearing the news.

Back in July 2015 New Horizons sent us the first really close shots of Pluto and its moons. The team took that real data plus digital elevation models and turned them into these cool flyover videos — basically letting us “fly” over the surface closer than the spacecraft itself ever did. This still comes from the "Soaring over Pluto" flyover. You’re looking at tall water-ice mountains rising up from the big smooth plains of frozen nitrogen in Sputnik Planitia. The colors are mostly burnt brown and bright white, with some orange patches and darker rough areas off in the distance.

Ever get that weirdly satisfying feeling when something finally goes way past its original plan?

Well, #NewHorizons just did exactly that. After 20+ years since launch, it's now farther from Pluto than it was back in 2006.

Really wild when you think about it.🔭 🧪 ⚛️

On the surface at least. If you count orbiters you can add Jupiter and the Moon.

An astronomical image featuring the backdrop of the dark night sky with a faint grey-blue speckle at the centre. The nebulous cloud has the shape of a four-leaf flower. Four orange laser beams are pointing to it.

This isn't a scene from #StarWars.

What you're looking at is the Tarantula Nebula. While those beams come from the lasers installed on the telescopes that comprise our VLTI.

But why are we sending lasers into the sky? Find out: https://www.eso.org/public/images/potw2616a/

Orbital view of a cloud formation over the icy north polar cap of Mars. The main cloud formation sits in the lower part of the ice cap and appears bright white, shifting to a slightly dustier tone closer to the ice cap. It resembles cirrus like clouds, formed in patches and curved bands shaped by wind. The polar cap below shows a spiral like structure, bordered by rust colored terrain with a faint hazy appearance.

I Cheerfully Refuse by Leif Enger is set in a near-future US in freefall (in terrifyingly plausible ways) but it also depicts communities working together to cope.
