back to article Captain, the computer has identified 250 alien stars that infiltrated our galaxy – actual science, not science-fiction

Deep-learning software has singled out a group of 250 stars in the Milky Way that appear to have been born outside our galaxy. That's according to a research paper published this week in Nature Astronomy. The oddballs, known collectively as Nyx, were described as a “vast stellar stream in the vicinity of the Sun,” by Lina …

    Build that Force Field!

    Who's gonna pay for it? .... Nyx's gonna pay for it!

    Who's gonna pay for it? ... Nyx's gonna pay for it, whether they know it or not!

      Shirley we're going to get the Nyxicans to pay for it ... Good thing Trump's Space Farce is such a viable success, eh?

    A couple of billion years ago, when the first and Second Galaxies were passing through each other

    and when myriads of planets were coming into being where only a handful had existed before, two races of beings were already ancient...

    Lemme know when they find Arisia and/or Eddore

          Rather an old one actually. I was reading his stories with a torch under bedcovers when I was a kid.

          I was convinced they were true stories!

            Yeah, always happy finding stuff on Gutenberg. With the local library still not fully open (they do have curbside delivery here, which i haven't experimented with yet), need to feed the brain with books (and not other brains...)

      I am new to this author, but I am particularly encouraged by the fact that he was also a food scientist who specialized in doughnuts and pastry mixes.

        More like a mining engineer who kept trying to marry my mother off to bright young mining engineers, his students, at science-fiction conventions she attended. She met all the authors in her "misspent youth" (her words, not mine).

      Pretty dreadful space opera junk that definitely shows it's age, but readable escapism nonetheless ... if you can find your way past the misogyny, implied racism, etc. etc. I've often thought that the core stories could make fairly decent movies, especially with today's special effects capabilities.

    So now we have Nyx

    Stars that have a similar chemical composition obviously come from the same local area, that much is understandable. That that many stars have the same movement characteristics is also an undeniable sign that they have something in common. Finally, we do know that our Milky Way has merged with dwarf galaxies in the past. So fine, we have a bunch of stellar immigrants nearby. Good for Science, we'll learn things.

    Now, though, I have a nagging doubt : are we sure our Sun is not also an immigrant ?

    I'm guessing that, with all the studying we've been doing on the source of Life in our Solar System, that fact would already have surfaced, but I can't keep from wondering.

      Human exceptionalism aside there is, as far as I know, no reason to suspect our solar system is extra galactic

      One problem I have with things like this is it seems to assume that anything outside a norm is not of here. I wonder whether there are other mechanisms that could be as validly applied to the Nyx - perhaps they were thrown inwards by a mass anomaly in one of the galaxies arms - just because the universe is 'uniform' now does now mean it always was and perhaps these are bits that haven't been normalised yet.

      Whatever , its fun to keep looking even if there's a bloody comet in the way and lots of sparkly satellites.

      I would think you could look at the chemical composition of the Sun & also its kinematics and conclude that it's probably not.

      This isn't meant to be a 'you idiot' answer: I have no idea if people have done that and it would be interesting as fuck if it was!

        Re: So now we have Nyx

        Off the top of my head: yes, this has been looked at and the kinematics and composition fit a star born in the Milky Way. Astrophysicists do this because they are looking for stars that might have been born with the Sun and clues about the environment that gave birth to it. But we've done so many orbits of the galaxy that everything is spread out and it's tricky to be certain. However I can't recall any suggestion we are anything other that a galactic native.

      I'm not sure how you can say that at all. Population III stars are practically defined to both nigh-identical in chemistry & from literally all over the universe.

      Certainly, there will be much more variability in population I stars, but even then, there's really not a lot of room to play with.

    Could they name some of the suspects?

    I would like to be sure which of our neighbors are suspicious migrants!

      This is an outrage calling us aliens when you are the alien race in this galaxy!

      We will be avenged when we work out how to use Tiktok, for some reason the cameras do not pick us up.

      The Puppeteer's pentagon shaped Fleet of Worlds was called a "Kemplerer rosette" in the books. Note that a Klemperer rosette must have an even number of objects, the Puppeteer's system had five.

    We're gonna build a wall around the galaxy...

    ...and the Small Magellanic Cloud is gonna pay for it!

    (Yes, I know others have done the wall joke, but *I* included a source of funding, making me a stabler genius than them!)
