    Stargazing 'Devil' comet visible tonight 21.04.24

    They can probably get something. It is just a pity that these kinds of articles always gets published for perihelion. If the comet is close to the sun in the sky it is much better to observe it, depending on the shape of its orbit, earlier (like in this case, it has been followed visually since...

    Stargazing 'Devil' comet visible tonight 21.04.24

    I think that will be tricker than the article assumes. It is very low in the sky and close to the sun, twilight and atmospheric absorption will be serious problem.

    Can Any Country Achieve Net Zero Without Nuclear?

    Not confusing at all or at least not more confusing than any other countries history of weights and measures. ;) A mile in Sweden (well from 1665, also called a uniform mile (enhetsmil) based on the older Uppsala mile, since before that the different regions of Sweden used their own regional...

    B Question about Hawking Radiation and Iron Stars

    Which is very fortunate since a new born baby would evaporate in a few femtoseconds while emitting a humongous amount of energy if it emitted Hawking radiation.

    Student Recreates the Archimedes Death Ray

    I think the first successful attempt I heard of to recrate this was in an old Usenet post by Henry Spencer but it had no reference. I think he could have been referring to an experiment by Ioannis Sakkas in 1973. When the Mythbusters failed MIT professor David Wallace and some students did a...

    B Debunking Bat and Skull Nebulae fakery

    To me the images are stolen and badly processed. While I don't condone it the least I would not say heavily altered. They went for a blue/monochrome where the original was red/yellow. A valid choice if done better I would say. Yeah, and that you claimed it was obviously fake is not a good look...

    B Debunking Bat and Skull Nebulae fakery

    Ok, so you think someone is wrong on the internet. I though we had (at least almost) established that the "skull" is a valid (if IMO probably stolen and badly processed) narrowband astrophoto representation of the Rosette nebula which would mean that everyone I have ever discussed this with in...

    Announcement Small PF update this weekend

    I noticed the same, however on macOS Safari it renders OK but you cannot log in and there is a bunch of scam, dating site ads and similar injected everywhere.

    That where we differ, I don't see a reason to "science" this question. If you want to know where the skull image came from with certainty the you need private detectives or the FBI to run down who started it.

    After literally 10 seconds of searching I think the skull is this one and then someone stole it and made it worse. https://www.astrobin.com/isf1eu/

    B Debunking Bat and Skull Nebulae fakery

    Yes, real. The "bat" is what I would expect for that object. The skull is a (in my opinion) badly overdone narrowband image of the rosette nebula but if you want to post on social media about a skull nebula that would be the most obvious to use. The things you ask about, the conclusion you draw...

    B Debunking Bat and Skull Nebulae fakery

    I'd consider that being able to conclude that both images are valid representations of the same thing is when you should stop your attempts at debunking one of them based on their appearance. Especially since it is obvious you don't know much about astrophotography. The images could still be...

    B Debunking Bat and Skull Nebulae fakery

    They are not reposting it! They are imaging it themselves. Can you not see that the images are all processed and cropped differently? Maybe this will be enough to convince you: I cannot link to the search but go to the European Southern Observatory - Digitized Sky Survey at...

    B Debunking Bat and Skull Nebulae fakery

    It very much does if you want to be able to determine if it is plausible that they are different representation of the same object.

    I might have been thinking about just those images when I posted...
