This is the thing, if "academia" wanted to stop this, we could easily tomorrow. Over 3 incorrect references? Rejected and forbidden to submit next year.
The purpose of a system is what it does!

The fundamental difference is that the discovery of unsecured servers is now trivial. I am assuming we'll see some shocking major breaches in the near future.

Three panels of the multiple stellar system mu Her. The top panel shows the widest view with ellipses showing the orbits of the stellar components. The projected ellipses are shown as 'shadows' cast onto the sky plane, and different components are coloured differently making a clean interpretation of the whole system.
Astrometric projection onto one of the ellipses. It looks like a giant olive pierced by about one hundred short cocktail sticks.
Marcussen+ solve a complex multiple stellar system in a very elegant paper: “The µ Herculis system solved after nearly three centuries”. It’s rare that the figures in a paper make me stop and say “Wow!” and I tip my hat to the authors for genuinely beautiful diagrams. Go take a look! #astrodon 🔭☄

We found out several things during the wait. 1) target uses AI for theft prevention which often falsely targets people. 2) they purposly don't notify you if you don't scan all items in a self checkout lane. 3) if u hit the ok button on the self checkout and you miss an item they say thats stealing
Apologies, I'm a complete random person dropping in on this, but just to say that's a absolutely fantastic piece of art, and I am very sorry for what happened to you. Sterkte.
We kind of tolerated Season 5 just to see it to the bitter end. It felt a bit like the "Hobbit" films in that I found myself going "It's almost finished! Oh wait, another two hours to go...." more than once...

Images of M stars and their surrounding environment. In one of the four panels, a candidate source is seen to the left of the main star.
Contrast curves for the M dwarf stars looked at, showing contrasts from 1e-3 down the majority of them at 1e-4.
Li+ on “A Search for Wide-orbit Planets Around M-dwarfs using Deep MIRI 15 micron Images” shows how the background sensitivity of JWST enables searches down to a few Jupiter masses for targets that are typically several gigayears old. #exoplanets #astrodon
In the past few days this image has impressed me more and more - as a professional astronomer who images planets around other stars, this really brought home to me the challenges in taking photos of rocky planets around the closest stars. It's tough!

The Integrity spacecraft just entered the lunar gravitational sphere of influence, at 0438 UTC Apr 6. Wiseman, Glover, Koch and Hansen are now the 25th to 28th humans to have left terrestrial space.
It's frequently pointed out that NASA activities (and basic/exploratory science in general) have a fantastic return on investment, contributing far more to the economy than they take. But even if they didn't, no one's actually taking from the "cure sick people" pot to put money in the "rockets" pot.
Amateur astronomers with telescopes equipped with video cameras are requested to look for impact flashes on the Moon tonight, to coordinate with #ArtemisII observations. Details here: www.geodes.umd.edu/impactflash

This post almost perfectly summaries my worries about AI in academia. Well worth your time.
Can’t open windows in space!
fantastic, thanks!r
hi @rami.spaceaustralia.com did you make a final version of your pulsar map? I was interested in seeing what you ended up with!
(and @erinleeryan.bsky.social is right on the money - September 2000 is the date I have for this photo)

Oh wow. Just.... wow. Lemon level eyerolling here.

Reflect Orbital finally have some numbers for their underwhelming service.
50 Watts per square metre for 20 minutes* in 2030 if they launch 5000+ satellites. This requires 750 satellites and if they charge $5000 per satellite per hour then this will cost just $750,000.

To the Federal Communications Commission: Reflect Orbital’s “Consolidation opposition and response to comments” document (Proposal SAT-LOA-20250701-00129) does not correctly address two key points that are critical to the feasibility and safety of their proposal. Reflect Orbital correctly state that EARENDIL-1 is a single pathfinder satellite, but it is only of scientific and engineering utility as a pathfinder if the resulting satellite constellation is a feasible means of generating solar power. This is clearly not the case and Reflect Orbital do not address the feasibility of their constellation in their response. An optimistic calculation (e.g. perfect flat reflective mirrors and ignoring satellite orientation) indicates that 3,000 satellites 54 metres on a side would need to be ~800 kilometres from a given location to provide just 20% of midday sunlight. As the satellites are in low Earth orbit and moving rapidly, providing relatively continuous light would require roughly 87,000 satellites. Reflect Orbital plans to charge $5,000 per satellite per hour (at noted in the New York Times), so this would cost $15,000,000 per hour for 3000 satellites. Even 2% of the midday Sun would cost $1,500,000 per hour. The vast number of satellites required for little illumination, plus the vast cost per hour, indicate that the project is not a feasible means of augmenting solar power generation. Fundamentally EARENDIL-1 is a pathfinder for an infeasible project. The risk of eye damage from EARENDIL-1 (and subsequent larger mirror satellites) is incorrectly dismissed. While Reflect Orbital correctly note that EARENDIL-1 will be a point source when viewed with the unaided eye, this is not the case when the satellite is viewed under magnification (i.e. with a hobby telescope). EARENDIL-1 will have an angular size up to 6 arcseconds, and this is easily resolved into a surface with small telescopes.....
For example, 6 arcseconds will project to roughly 60 micron on the retina when viewed at 100 times magnification, which is larger than the 25-50 micron point source threshold noted in Reflect Orbital’s response (larger production satellites will be resolved at even lower magnifications). There is a risk that members of the public with small telescopes will accidentally view a mirror satellite with a surface brightness comparable to that of the Sun and there is a corresponding danger of eye damage. Comparing EARENDIL-1 to other satellites to assess eye damage has major flaws. Comparing EARENDIL-1 to the International Space Station is invalid as the latter is not a designed to be a reflector and is thus far fainter than EARENDIL-1 is intended to be. Direct comparisons of EARENDIL-1 to Znamya are also invalid, as this satellite was both smaller and its reflecting surface was visibly crumpled, vastly reducing its surface brightness when viewed from Earth. EARENDIL-1 is intended to have a higher surface brightness than both the International Space Station and Znamya – indeed it must be or the feasibility of Reflect Orbital’s project will be even worse than what is discussed above. To summarise, Reflect Orbital’s proposal has significant feasibility and safety issues that have not been addressed. While EARENDIL-1 is intended to be a pathfinder, it is not of engineering and scientific utility as it is a pathfinder for an infeasible project. If EARENDIL-1 is both very flat and reflective as intended, then its surface brightness will be comparable to that of the Sun (and far brighter than previous satellites). Members of the public may thus suffer eye damage if they accidentally view and resolve EARENDIL-1 with small telescopes.
I've submitted a reply to the FCC regarding the response by Reflect Orbital to comments from the public and organisations on their crazy space mirror project.
My critique is they want to launch a pathfinder for an infeasible project and they haven't properly addressed the risk of eye damage.
