Fireball ‘100 times the size of the solar system’ thought to have been caused by gas being sucked into supermassive black hole
https://www.theguardian.com/science/2023/may/12/astronomers-capture-largest-cosmic-explosion-ever-witnessed
Fortunately, this is about 8 billion light years away.
But it’s been going for over three years now.
Yow.

The word has just come in that a fellow traveler has set up his own blog about science.
It’s called Science.
(In Latin, Scientia.)
Glen is a good friend of mine, and not only is he a good scientist, he’s also a good writer. His avowed goal is to raise science literacy and share his love of science with the world.
We may even steal posts from each other from time to time. Or photos (like the one above ⬆️🌏).

Scientists have found a way to decode a stream of words in the brain using MRI scans and artificial intelligence.
https://www.npr.org/sections/health-shots/2023/05/01/1173045261/a-decoder-that-uses-brain-scans-to-know-what-you-mean-mostly
While not perfect, this is some seriously scary stuff.
FWIW the researchers themselves did recognize this…
Although it’s nowhere near being able to decode spontaneous thoughts in the real world, the advance raises concerns that, with improvement, the technology might mimic some type of mind reading. “Our thought when we actually had this working was, ‘Oh my God, this is kind of terrifying,’” Huth recalls.

Participants have to consent to being “read,” and there are ways to prevent the software from figuring out even the “gist” of what they were thinking.
Still, imagine if some nefarious criminal group (or governmental agency, if there is a difference) decided to force someone to consent to have their thoughts read.
Long distance.
Permanently.
It’s getting harder and harder to distinguish scifi from reality.

“We have to assume that we could not complete the landing on the lunar surface,” Hakamada said.
https://www.cnbc.com/amp/2023/04/25/ispace-moon-landing-watch-live.html
Or…
…Ispace engineers observed that the estimated remaining propellant was “at the lower threshold and shortly afterward the descent speed rapidly increased.”
https://www.nytimes.com/2023/04/25/science/ispace-moon-lander-japan.html
Or as the New York Times reporter succinctly puts it: “In other words, the spacecraft ran out of fuel and fell.”
Another “hard landing on the lunar surface.”
I.e., it crashed onto the Moon and went kablooie.
So much for private company based space exploration.
Spaceships are having a difficult week…

Led by the European Space Agency (ESA), the mission will orbit the largest planet in the solar system and explore its icy moons, which scientists think could support living organisms.
JUICE will explore three possible ocean-bearing moons – Europa, Ganymede and Callisto. Under their icy surfaces are thought to be huge oceans of water – a crucial ingredient for life as we know it.
https://www.aljazeera.com/news/2023/4/13/explaining-juice-mission-to-jupiter-and-its-moons
The “Jupiter Icy Moons Explorer” is the first time an ESA-headed project will visit another moon.
If it launches successfully, of course.
Lift off in less than seven hours from French Guiana!
Great job by Alzajeera, although “Earth is about 4.1 times the size of Europa and is believed to have a young and active surface that may vent water vapour to space via plumes and geysers.” is a bit misleading (Europa, not Earth, is believed to have…)
Copy editor!
🤞 🚀 🇬🇫
UPDATE
The launch was successful, and the 90 m2 solar array also deployed successfully.
Now we just have to sit and wait until 2031!

I learned in high school how much I wanted to graduate and never come back.

The bankruptcy filing by Richard Branson’s Virgin Orbit Holdings Inc (VORB.O) has dealt a blow to Japan’s hopes of building a domestic space industry, with plans for a Kyushu-based spaceport designed to attract tourism on hold for lack of funding.
https://www.reuters.com/business/aerospace-defense/virgin-orbit-bankruptcy-casts-shadow-over-japans-space-dreams-2023-04-07/
Granted, this news is from four or five days ago.
Still, it’s jarring to see TV news about JAXA and NASA doing “joint” explorations of Mars, and then see a constant failure of JAXA to do anything based in Japan.
Something is seriously wrong with this space agency. And I suspect it has nothing to do with the scientists or astronauts.

Seriously. I don’t blog about exercise.
Huh?
That said, I do tai chi.
So there. 😆

The astronauts will be the first humans to fly in the vicinity of the moon in more than 50 years. They will also be the first to launch aboard NASA’s next-generation megarocket and Orion space capsule. The crew will not land on the moon but will swing around the celestial body, testing the performance of the Orion spacecraft, before returning to Earth.
https://www.nbcnews.com/science/space/nasa-announces-astronauts-will-orbit-moon-year-rcna77896
They won’t land, only orbit. But a first is a first.
Let’s go to Mars, already.

Mercury is a planet that just doesn’t make sense. It’s incredibly small yet hosts a relatively massive core. Mercury is so strange that astronomers have not been able to explain its properties with simulations of the solar system’s formation. But now, researchers have found an important clue, and Mercury’s weirdness appears to be the fault of the giant planets.
https://www.space.com/mercury-weird-because-of-jupiter-outer-planets
Basically, Mercury is nearly as dense as the Earth despite being less than 6% the size. This is due to the gas giants in our solar system yanking material (“planetesimals” and protoplanets) and ejecting it from the solar system, leaving Mercury with very little material left to form itself.
But there are plenty of questions still…
