TIL about Przybylski's Star, which appears to have elements in its atmosphere heavier than plutonium that we previously considered human made only. There are not many explanations for this, one is that they are decay products from the island of stability. Another is aliens, as it matches predictions that were previously made for aliens doing nuclear waste disposal or communication (as suggested by Carl Sagan).

I wouldn't put too much trust on the ability to infer the compositon fo stars from the detected spectra and out current models. Certainly not enough to resort to aliens as a possible explanation for surprising measurements.

The brightest object in the universe is a quasar so bright we thought it must be a close star

Astrophysicists just spotted the brightest and fastest-growing supermassive black hole — and it turns out, it was hiding in plain sight for decades.

Dubbed J0529-4351, the quasar was so bright that it was first dismissed as a star. Described in a paper published in Nature Astronomy, the quasar has a mass of 17 billion Suns and it’s still growing. The black hole is consuming the equivalent of one Sun per day, shining brighter than 500 trillion Suns and making it the brightest known object in the universe.

J0529-4351 was first noted in a sky survey in 1980 but was not categorized as a quasar until last year. Automated analysis of data from ESA's Gaia satellite instead earmarked the quasar as a star because it seemed too bright to be anything else.

Astrophotographer Eduardo Schaberger Poupeau captured the moment an enormous solar flare erupted from near the Sun’s south pole on 17 February. Most solar flares happen around the Sun’s equator — the unusual location of this one could be a sign that the Sun is about to enter the most active phase of its roughly 11-year cycle, the solar maximum. The 200,000-km-high jet of plasma eventually broke off and flew into space as a gigantic cloud, known as a coronal mass ejection.

too many consecutive posts these days ... so , like here .

the PM has been deceived again .


these are various images of F-24G versus the F-22 . For the British the entire rationale of the F-24G programme these days is the forthcoming Rolls Royce engine for their joint work with Italy and Japan . It is sized somewhat in a medium range to end a line from some competitor company based on the latter's recent success in civilian airliner engines , which was still nowhere as bad as 1971 . For the Party once Qatar learned they were not getting anything free (or even at cost or even more) it became a PR issue . That's how the PM was told maybe a prototype could be made and that could be as large as the Su-27 because that one is huge and people do have no way to measure stuff but size can be gauged by eye . (Even if the PM has a picture in a mockup or the current airframe or whatever) So , last year the F-24G was really Flanker size or possibly even bigger . This year , it is not so . It's crazies who said this and did that ... Unless the Opposition can lease a Flanker , nobody will care . Except ...

them good old Brits already are claiming the F-24G wing area is 60 sqm , less than what should be 78 or whatever and they will have it downsized so that they can sell their engines even when they have to cancel theirs . KF-21 is Korean and a likely candidate for the British engine as well . Let us see if you can sell me a Rolls Royce .

the small one always F-22 even if in reality they will be just about the same size ...


a second jet behind the F-22 , that's why it looks AI like .

First antenna is installed on Square Kilometre Array Low telescope, as traditional owners welcome project

As first antenna is installed on groundbreaking 'time machine' telescope, traditional owners welcome project

As the first antenna is installed on the world's largest radio telescope in outback Western Australia, traditional elders say the $3 billion project brings hope for more opportunities in the desert region.

yay , even before the Russian nukes in space could be commented upon , America tells the world that 4 Apollo complexes to travel to the Moon have been going around in formation in some American test site and the radar on the American fighter jet went out of order like with telekinesis to knock down some switch and F-22 has mighty powerful IR cameras all around and stuff . But yes , an American fighter pilot came within 4 kilometers of an UFO but ı would never , not just because ı am not a pilot but America is best .

translation: It's a slow day in Pentagon with nothing to brag about . But strangely comes close on the heels of some British person saying they might fight some random people on the moon over rare earths , like without declaring war or something . See , Apollos intercepted by Raptors .

Died by a "self inflicted wound" while in the process of testifying against Boeing in a whistleblower lawsuit? Sounds a little fishy to me.

Boeing whistleblower found dead in US

A former Boeing employee known for raising concerns about the firm's production standards has been found dead in the US.

In the days before his death, he had been giving evidence in a whistleblower lawsuit against the company.

It said the 62-year-old had died from a "self-inflicted" wound on 9 March and police were investigating.

basically attacked online by everyone , including US Goverment mouthpieces on various forums . Described as unreliable and whatnot . You can even make people commit suicide by threatening people they hold dear . Which is technically "self-inflicted" . When the next generation US combat aircraft market is decided it will end . Boeing still trying to get at least the Navy contract .

The telemetry stopped at 8:04 with a flash as Starship blew part of itself up to abort.
The Flight Termination System (FTS)

Emergency Flight Termination System for SN10 is in place; Starship test flight imminent - SpaceFlight Insider

SpaceX recently installed the flight termination system on Starship SN10 in what has proven to be a key event that signals a flight attempt.

www.spaceflightinsider.com

Here is a telescope that saw the flash and zoomed in at 8:10 to see the following minute

Death spiral at 100 miles up.

If anyone watches the original full video, at 7:06 Starship turns from a large glowing dot into a bushy-tailed comet
The Liquid Oxygen Gauge (LOX) starts falling a lot faster than the Liquid Methane Guage (CH4) over the next 60 seconds.
Fuel leak?

After a minute of that I guess the computer calculated there was no way to achieve the mission.
CH4 needs the Liquid Oxygen to combust and burn in space.

So a bunch of months later, Starship Launch #3 was attempted today on March 14th, 2024.

It worked!
Mostly.
Didn't quite get the re-entry.

If they can get it to work, we can have crazy good satellite internet, moon missions, and Mars missions because not everything will have to be folded up like an accordion.
Starship is very roomy.

SpaceX effectively has demonstrated they now have an expendable rocket with more payload to orbit than a Saturn V. That is absolutely incredible! Hopefully they can figure out landing faster for this than for the Falcon 9.
