  Common, no shark is that old, not to mention all of them.

  45-67Million Years according to Wikipedia.

  Sharks are hundreds of millions.

      Not directly relevant, but I think Keanu Reaves named his band “Dog Star” because he was “Sirius” about his music career.

  Sharks are also older than trees, flowers, Saturn’s rings, and the Atlantic ocean.

    And don’t even get me started on horseshoe crabs. Older than plants, those ones.

      In defence of plants, it takes a highly evolved form of life to be able to do nothing all day and get away with it.

      From Wikipedia:

      Horseshoe crabs have been described as “living fossils”, having changed little since they first appeared in the Triassic.

      Those fuckers have like nine different types of eyes. Even that tail is one big photoreceptor! Primitive, my ass - you try surviving crawling around in the mud for 400 million fucking years.

      Back in my day you used to be able to buy twelve horseshoe crabs for a nickel… Of course that was before the war… Back then id swear at least two and a half teenth of my crew where horse shew crab but who you going to tell ? Tattling wouldn’t be invented for another 2 score years up in Kentucky you had to wait another 6!

      But it’s was easier and I miss those days. If you could dodge the knowledge toads you were already 12 up on these Irish but we can’t say that anymore can we? No sir…now we got to give everything to the freckled folk and act like that’s the way it’s meant to be but it’s not. It wasn’t a thing until the battle of leaky hill… But we lost and I had to accept that to get tomatoes down at the Paul’s service at a decent price. Don’t even get me started about the tomatoes. You never damn believe it.

      Sorry I’m going to be a grandfather soon so I’m practicing

    I would cut the shapes of prehistoric sharks in cardboard in my childhood. Have a pouch of those somewhere.

    They were really beautiful.

  Also from Wikipedia:

  Although appearing to the naked eye as a single point of light, Polaris is a triple star system, composed of the primary, a yellow supergiant designated Polaris Aa, in orbit with a smaller companion, Polaris Ab; the pair is in a wider orbit with Polaris B. The outer pair AB were discovered in August 1779 by William Herschel, where the ‘A’ refers to what is now known to be the Aa/Ab pair.

  I learned something new today. And if I’m reading the details section correctly, while the outer pair of stars are actually older than sharks, it’s the bright star that you can actually see that’s younger than sharks.

    This makes even less sense, how is the heavier thing in the middle younger than the things that orbit it?

      I may be wrong but a mass of inhert hydrogen has the same mass of a radiating one, so they could have been orbiting a mass of gas a long time before the “newer” one ignited.

      The bigger the star, the brighter it burns

      Also it dies sooner. So any given big star is more likely to be young

      I can explain that but I have to use the only thing available to illustrate.

      So imagine my left testicle here formed before this penis in the middle… And yes it is technically a penis despite the small size, and this testicle-

  Youngest star is 1300 years old…

  So most species are older than HOPS-315.

• doomsel@lemmy.world ⁨17⁩ ⁨hours⁩ ago

  If I understand correctly, it is 2billion years old, but 50million years ago it merged with another star, making it more massive and thereby more bright an visible from earth. Fun fact: Due to it beeing a yellow supergiant it will turn red in a couple of thousand years and then die quiet soon.

    “soon” and “young” are always interesting terms in Geology and Astronomy.

  I love it. it feels like Polaris will be there long after this rock is barren and cold, and we can continue to navigate by it in the gay space communism

  • dwindling7373@feddit.it ⁨5⁩ ⁨hours⁩ ago

    Apparently the star is going to fizzle out soon, but beside that, if you are not on earth it becomes irrelevant for navigation.

  Stars have only existed for about fifty years. Duh.

    How can the stars have existed for fifty years when the universe itself is only slightly under a week old?

      I could explain, but there’s a lot of string theory involved and I only have limited time.
