Jupiter might very well have fecked Venus over, and they're more than 575 million miles away from each other at their farthest.

That flew so far over my head I think it passed a few black holes.
It will fly over nearly everyone's head given its a concept still in its relative infancy.
The clue is in the name, it's dark because it's never been detected, we don't even know it anything like it actually exists and is pure inference to make the numbers match observations.
21st century epicycles.
Yes same here. About as understandable as String Theory.
Very good.String theory is easy.

Peter Higgs, physicist who proposed Higgs boson, dies aged 94
Nobel-prize winning physicist who showed how particle helped bind universe together died at home in Edinburgh
Peter Higgs, the Nobel prize-winning physicist who proposed a new particle known as the Higgs boson, has died.
Higgs, 94, who was awarded the Nobel prize for physics in 2013 for his work in 1964 showing how the boson helped bind the universe together by giving particles their mass, died at home in Edinburgh on Monday.
After a series of experiments, which began in earnest in 2008, his theory was proven by physicists working at the Large Hadron Collider at Cern in Switzerland in 2012; the Nobel prize was shared with François Englert, a Belgian theoretical physicist whose work in 1964 also contributed directly to the discovery.
[...]
The Royal Swedish Academy of Sciences, which awards the Nobel, said at the time the standard model of physics which underpins the scientific understanding of the universe “rests on the existence of a special kind of particle: the Higgs particle. This particle originates from an invisible field that fills up all space.
“Even when the universe seems empty this field is there. Without it, we would not exist, because it is from contact with the field that particles acquire mass. The theory proposed by Englert and Higgs describes this process.”

I loved that he got the highest award so long after his theory was proposed. The ultimate vindication. What a legend and a really good age to live to. RIP

Researchers have discovered the cause of the brightest burst of light ever recorded.
But in doing so they have run up against two bigger mysteries, including one that casts doubt on where our heavy elements - like gold - come from.
Proving that every day we know more about less....

CSIRO telescope detects unprecedented behaviour from nearby magnetar
Captured by cutting-edge radio telescope technology, a chance reactivation of a magnetar – the Universe’s most powerful magnets – has revealed an unexpectedly complex environment.
https://www.csiro.au/en/news/All/Ne...edented-behaviour-from-magnetar-XTE-J1810-197
Dr Marcus Lower, a postdoctoral fellow at Australia’s national science agency – CSIRO, led the latest research and said the results are unexpected and totally unprecedented.
"Unlike the radio signals we've seen from other magnetars, this one is emitting enormous amounts of rapidly changing circular polarisation. We had never seen anything like this before,” Dr Lower said.

Or the 21st century positron.
It's either see it now, or in 2095, chaps!

Voyager 1 is now sending back readable messages.
First launched in 1977, it is now some 15 billion Kms from earth and moving at 15 Kms/second.
It is powered by the heat given off by the decaying Plutonium being converted into electricity.
This is incredible and can arguably be classed as one of humanity greatest achievements.

What the engineers have done to diagnose and fix the issue is amazing. They've had to go back to the original blueprints to diagnose and attempt to fix a hardware fault and remotely send commands to bypass bits of onboard memory that had stopped working.
NASA knows what knocked Voyager 1 offline, but it will take a while to fix | Ars Technica
It is indeed an extraordinary thing to have been able to diagnose and resolve the problem. Especially given the massive distance which takes a radio signal over 22 hours to reach the satellite, one way.
NASA has managed to move the processing to another part of the computer.
A computer designed way back in the mid 1970s.
I made a mistake in the distance. It is actually 20 billion Kms from earth and moving towards the centre of the galaxy.
Just a mind-blowing piece of technology.
Actually... no.
Which also is exactly why it still works, proper engineering, redundant, simple and robust, but not at the height of technological development (even at the time it was launched). Reliability was key for that thing.
Only another 40,000 years until it reaches Proxima Centauri. During that time, humans will have probably created propulsion technology to get them anywhere in the galaxy significantly faster.
500 million years until it leaves the Milky Way, although with the Andromeda collision only 4b years off at that point, I'm assuming gravity will pull it towards Andromeda and eventually back into Milkomeda. That's if it doesn't crash into something before.
It was from an age of incredible pieces of technology achievements, in the late 1960/1970s.
Including the NASA Apollo programme and something equally impressive, Concorde.
This age was described as the White Heat of technology when anything and everything seemed possible.
In not much more than a couple of decades, we had gone from the first manned supersonic flight, in a dive, to producing a successful supersonic jet liner with 100 passengers flying at twice the speed of sound.
Developed the first nuclear and then the first thermonuclear bomb as well as nuclear power.
And landed men on the moon and brought them back successfully as promised just a few years earlier.
Now in 2024, the only people who can fly at supersonic speeds, for a few minutes, are the odd fighter pilot strapped into an ejection seat and certainly not sipping champagne. And supersonic passenger travel is still some way off.
And we are no nearer to being able to land a person on the moon either.
So yes I would describe it as a fantastic piece of technology.
IMO the James Webb Space Telescope is one of the most impressive things humanity has ever done. Landing on the moon is nice, but we shouldn't go blind to other achievements over it. There's a reason they stopped going to the moon, after all.
The first time was an incredible achievement. The sixth one? Did we really learn anything from it? I'm sure they did some science, but there's plenty of lunar rocks to go around for science back on Earth, and we've learned a lot more since then from the amazing ISS.
I think part of the interest in getting back to the moon is the possibility of setting up a new telescope that can see better into infrared and electromagnetic than Webb.
Oh yeah, I definitely think there's human interest in going back to the moon, and then further out.
