    Horologium Supercluster

    Hi -

    No, it's not a new watch brand or model...

    For something totally unrelated at work, I ran across a reference to the Horologium Supercluster. It's a group of galaxies that form a supercluster of galaxies between 700mn and 1.2bn light years away, 550mn light years across and has a mass of around 10^e17 solar masses. It's in our southern hemisphere, around -60° declination. It includes the object Abell 3266, the largest "ball of fire" around, a mass of gas larger than 3 mn light years that masses billions of solar masses and is moving at 750 km/s. Temperature? around 100 million degrees.

    The Horologium Supercluster is actually named after a watchmaker, Christian Huygens. He invented the pendulum clock, and there is a constellation bearing his name, so designated in the 17th century by Nicolas Luis de Lacaille, a French astronomer who was one of the first cataloguer of stars in the southern hemisphere (who died of gout!).

    The supercluster is in this constellation, hence the name.

    This has been your completely useless watch-related trivia of the day, brought to you by the good folks at WUS.

    Not completely useless, I now know that star thingy is pretty hot.


    Understeer is when you hit the wall with your front end. Oversteer is when you hit the wall with your rear end. Horsepower is how hard you hit the wall. Torque is how far you move the wall.

    between 700mn and 1.2bn light years away,

    I guess this is in fact somewhat far away?
    Got a new watch, divers watch it is, had to drown the bastard to get it!

    Hi -

    Farther than I can spit, that's for sure...

    PS:6.62236988 × 10^21 kilometers

    That's 6,622,369,880,000,000,000,000 km away at the closest. Then again, I'm rounding...

    Thanks for that bit of trivia. Always good to see some of the "other" real world besides our watches. Sort of makes a watch that is a few seconds off seem a bit, how should i say it, trivial? lol
