Wake me up when there is 4K video of alien cities lighting up as dusk falls. No one could care less about star farts and artlessly arranged galaxies.

Point your white balls to the skies folks, it's Perseid meteor shower season. Caught 2 ripping the sky a new one tonight. They always come around this time of year. If you can get yourself somewhere out of the urban sprawl and remote (wyh has extensive knowledge of such 'spots') you may just be treated to a galactic feast 🌠

William Shatner: My Trip to Space Filled Me With ‘Overwhelming Sadness’ (EXCLUSIVE)

In an excerpt from William Shatner's new book, 'Boldly Go,' the 'Star Trek' actor reflects on his voyage into space on Jeff Bezos' Blue Origin space shuttle on Oct. 13, 2021.

I love the mystery of the universe. I love all the questions that have come to us over thousands of years of exploration and hypotheses. Stars exploding years ago, their light traveling to us years later; black holes absorbing energy; satellites showing us entire galaxies in areas thought to be devoid of matter entirely… all of that has thrilled me for years… but when I looked in the opposite direction, into space, there was no mystery, no majestic awe to behold . . . all I saw was death.

I saw a cold, dark, black emptiness. It was unlike any blackness you can see or feel on Earth. It was deep, enveloping, all-encompassing. I turned back toward the light of home. I could see the curvature of Earth, the beige of the desert, the white of the clouds and the blue of the sky. It was life. Nurturing, sustaining, life. Mother Earth. Gaia. And I was leaving her.

Everything I had thought was wrong. Everything I had expected to see was wrong.

I had thought that going into space would be the ultimate catharsis of that connection I had been looking for between all living things—that being up there would be the next beautiful step to understanding the harmony of the universe. In the film “Contact,” when Jodie Foster’s character goes to space and looks out into the heavens, she lets out an astonished whisper, “They should’ve sent a poet.” I had a different experience, because I discovered that the beauty isn’t out there, it’s down here, with all of us. Leaving that behind made my connection to our tiny planet even more profound.

It was among the strongest feelings of grief I have ever encountered. The contrast between the vicious coldness of space and the warm nurturing of Earth below filled me with overwhelming sadness. Every day, we are confronted with the knowledge of further destruction of Earth at our hands: the extinction of animal species, of flora and fauna . . . things that took five billion years to evolve, and suddenly we will never see them again because of the interference of mankind. It filled me with dread. My trip to space was supposed to be a celebration; instead, it felt like a funeral.

The Cosmos Is Thrumming With Gravitational Waves, Astronomers Find

Radio telescopes around the world picked up a telltale hum reverberating across the cosmos, most likely from supermassive black holes merging in the early universe.
www.nytimes.com www.nytimes.com

On Wednesday evening, an international consortium of research collaborations revealed compelling evidence for the existence of a low-pitch hum of gravitational waves reverberating across the universe. The scientists strongly suspect that these gravitational waves are the collective echo of pairs of supermassive black holes — thousands of them, some as massive as a billion suns, sitting at the hearts of ancient galaxies up to 10 billion light-years away — as they slowly merge and generate ripples in space-time.

“I like to think of it as a choir, or an orchestra,” said Xavier Siemens, a physicist at Oregon State University who is part of the North American Nanohertz Observatory for Gravitational Waves, or NANOGrav, collaboration, which led the effort. Each pair of supermassive black holes is generating a different note, Dr. Siemens said, “and what we’re receiving is the sum of all those signals at once.”

"Scientists on Monday announced the discovery of a scorching world with temperatures of up to 2,000 degrees Celsius (over 3,600 degrees Fahrenheit), where glass-like silicate and metals boil into clouds."

Astronomers have detected a rare and extremely high-energy particle falling to Earth that is causing bafflement because it is coming from an apparently empty region of space.

The particle, named Amaterasu after the sun goddess in Japanese mythology, is one of the highest-energy cosmic rays ever detected.

Only the most powerful cosmic events, on scales far exceeding the explosion of a star, are thought to be capable of producing such energetic particles. But Amaterasu appears to have emerged from the Local Void, an empty area of space bordering the Milky Way galaxy.

“You trace its trajectory to its source and there’s nothing high energy enough to have produced it,” said Prof John Matthews, of the University of Utah and a co-author of the paper in the journal Science that describes the discovery. “That’s the mystery of this – what the heck is going on?”

Couldn't it have just curved around some gravity well at some point along its path? @Mr. Tea would there be any way of discerning whether or not it did, based just on what is measurable upon its detection here? I don't think so.

Maybe if it had a certain spin, relative to the spin a particle of that kind would be expected to have? I don't know if bending around gravity wells would even effect the spin of particles like this.

I'd say more likely that it's been deflected by a very powerful magnetic field (on the assumption that it was either a proton or an atomic nucleus, i.e. a charged particle, which seems likely).

Another possibility is that @version has just made this all up and put the word 'Science' in green to make it look official.

I know less than nothing about this but the article I read said that the energy level it had was so high that it couldn't be deflected by any magnetic field. Apparently apart from one thing in 1993 it is the highest energy ray ever measured. What's strange is it comes from what they thought was empty space which can't be explained and there is also no way - that's understood - it can be deflected from elsewhere.

If I had to guess I'd say it's probably someone read the instruments one.

I don't think a particle could be so energetic that it couldn't be deflected by any magnetic field - the particle would have to be infinitely energetic in that case - but perhaps they meant 'any plausible astrophsyical magnetic field source that we know of'.

Having said that, there's a species of neutron star called a magnetar that has an insanely strong magnetic field, but perhaps a charged particle screaming past one of these at almost the speed of light would lose most of its energy as synchrotron radiation (radiation given off by charged particles as they move in a circular path).

Having said that, I'm not sure this really buys us anything, since the particle came from out of a region of apparently empty space.
