Is Planet Nine real? A new study may have just found the strongest clue yet. By analyzing decades-old infrared data from IRAS and AKARI satellites, scientists have spotted a slow-moving object in the outer Solar System—exactly where Planet Nine is predicted to be. If confirmed, it would be the first new planet discovered in over 170 years. Dive into the science, the discovery, and what it means for our cosmic future in this exciting episode.

A Solar System mapping orbital observatory (maybe a trio of them; one each at a couple of Lagrange points and a stationary one on the backside of the Moon) would be a great addition to current capabilities.

Wait... 140 bucks... does your wife know about this?!? ;^) :^D

There are certain things in a marriage that are best kept private. Every woman is entitled to her secrets, but so is a man, even if mine are not at all saucy. BTW, the book was more than worth it, though it is just a bunch of disconnected essays of varying quality.

There is an interesting chapter on the contemporary American reaction, and several of the essays are by modern Americans. I think the Americans had the best take on the whole affair. In couple of generations, by 1900, Americans would be the most capable and productive astronomers in the world, and seeds were obvious by 1846.

Yes, and George Knapp is good too. He occasionally subs for the dullard Noory..

:^) This one’s down to $115:

I guess we’ll find out for sure if fluoride gets banned. ;^)

Couldn’t find it used (apart from Amazon, still $100) but there are ample supplies of new copies, and there are related archival works that will likely be of interest:

He was ok when Art was not there but after Art passed I stopped listing after Rush passed i stopped listening to most talk radio I also tuned Arts show just a little off station so it cracked a bit added to the effect

It started with a speck. Just a faint dot in two separate sky surveys, one from 1983, the other from 2006. At first glance, it's nothing remarkable. But if astronomers are right, this unassuming blip might be a colossal discovery: the elusive, long-hypothesized Planet Nine.

The new candidate object shows a shift of 47 arcminutes across 23 years, an incredibly slow movement that suggests it could be orbiting the Sun from great distance. Its infrared brightness implies a mass possibly exceeding Neptune's.

But there's a catch: its orbital tilt doesn't match predictions. Mike Brown himself reviewed the findings and cast doubt, noting that this object's extreme tilt (around 120 degrees) doesn't align with the expected orbit of Planet Nine.

Still, even if this isn't the planet astronomers have been chasing, it's something. And in the vast, dim reaches beyond Neptune, even a false lead can point us toward deeper truths.
