Man, if I were Pluto, I'd be suffering a major identity complex....

Pluto May Actually Be A 'Giant Comet,'


“We found an intriguing consistency between the estimated amount of nitrogen inside [a glacier on Pluto] and the amount that would be expected if Pluto was formed by the agglomeration of roughly a billion comets or other Kuiper Belt objects similar in chemical composition to 67P, the comet explored by Rosetta,” said Southwest Research Institute’s Christopher Glein in a press release.

Based on its chemical makeup, Pluto could simply be a “giant comet,” or as Glein said, the result of a billion comets coming together.

Incredible footage from JAXA's Explorer “Hayabusa2” as it lands and collects a sample from Asteroid Ryugu just a few days ago, 250 million km away from Earth!
JAXA’s Asteroid Explorer “Hayabusa2” collected a sample from asteroid Ryugu on 22 February 2019. The touchdown was captured using the onboard small monitor camera (CAM-H). The image of the site immediately after touchdown was taken with the Optical Navigation Camera – Wide angle (ONC-W1) on 22 February 2019.

[B]Planet 9 Might Not Be a Planet[/B]


"What if Planet 9 is a Primordial Black Hole?" That's the title of a new paper about the mysterious gravity source at the edge of our solar system, Business Insider reports. Posted Tuesday on arXiv, the paper suggests that the still-unseen source—which some call Planet Nine, or Planet X—could actually be a small primordial black hole. That apparently fits what scientists see way out there, 20 times further than Neptune, where ice chunks have their own oval-shaped orbit in what's called the Kuiper Belt. Authors Jakub Scholtz and James Unwin, both physics PhDs, urge us to consider the notion of a relatively close black hole.

"By simply focusing on the concept of a planet, you restrict the experimental search that you’re undertaking," Unwin tells Gizmodo. "Once you start thinking about more exotic objects, like primordial black holes, you think in different ways." They say such a black hole might have been flying by when it got caught in an orbit of our solar system. For the record, primordial black holes are theoretical objects that might have been created soon after the Big Bang. And this one would be small, with a mass roughly 5 to 15 times that of Earth and size between a wallet and a bowling ball. The paper hasn't been peer-reviewed, but still, it's a thought.

Now that's an intriguing possibility.

Ceres - who'da thunk it?

Remember a couple of years ago, when we first saw the images of the "bright spots" at the bottom of a crater on Ceres when the probe visited, and we had fun speculating on everything from alien bases to... well, alien bases... what else could it have been?



Here's the latest conclusion:

Dwarf planet Ceres is an 'ocean world' with sea water beneath surface, mission finds


The dwarf planet Ceres – long believed to be a barren space rock – is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed on Monday.

Ceres is the largest object in the asteroid belt between Mars and Jupiter, massive enough to be shaped by its gravity, enabling the Nasa Dawn spacecraft to capture high-resolution images of its surface.

Now a team of scientists from the United States and Europe have analysed images relayed from the orbiter, captured about 35km (22 miles) from the asteroid.

They focused on the 20-million-year-old Occator crater and determined that there is an “extensive reservoir” of brine beneath its surface.

Hello, Bigot.

While an interesting read, leave it to The Grunion to call Ceres a planet. Guess they never took astronomy in Social Justice class...

Maybe it is YOU that should have paid better attention with your astronomy learning...!!!

But maybe just leave it to show your lack of ignorance... idiot...and name caller!!!

Also rather disturbing your obsession with me - how you take every opportunity to reveal your character in threads where one would hope civility could prevail.

Alas, the leopard cannot change his spots.

Truly sad the depths to which Canada's Mac Community has fallen....

+1!!! And the ongoing immaturity of such comments and the language gets boring after a while, and got so a long time ago.

Not even any complaints to the Admins have helped improve such comments or caused any changes.

Unfortunate for what used to be a nice helpful Mac site!!!
