back to article Amateur astroboffins spot young brown dwarf playing with planet-forming hula hoop just 102 parsecs from Earth

Disk Detective-using researchers have spotted a brown dwarf, plus protoplanetary disk, 332 light years from home. Brown dwarfs are objects that are too big to be a planet, but too small to be a star. Formed by a gravitational collapse of gas and dust, like stars, the fusion process does not kick off within brown dwarfs, making …

    Nice artists impression.

    Did they miss the inference that 'no fusion' means no bright light source? (it's mostly just IR)

    Sorry..being picky

      The artist must have been working in infrared shifted to be visible to normal human vision....

      No fusion perhaps but you can still get pretty warm just collapsing in on yourself - the earth was probably 3,600° Fahrenheit around the time of its' creation. That would make your bum glow!

        Come on: S.I. or El Reg units only for science stuff, please, none of this 18th century hand waving.

          Not sure of the reg units of temp. Neve seem to be able to find them when I need them. Try twice a kebab in an afterburner.

        A brown dwarf is by definition massive enough to fuse deuterium and lithium in its core, so they can get quite toasty for a few million years.

    Somewhat confusing....

    making for a dim object that is tricky for astronomers to observe

    So, as dwarfs go, does this make it Dopey or Bashful?

    Yummy

    Planet sized Hula Hoop you say? Where can I sign up to colonise this? Assuming it's BBQ flavor..

    Confusing units in article

    I think Richard meant about 1.05 x 10^31 double-decker buses...

      Sheesh!

      You wait ages for one bus, then along come 10^31. Should have enough seats for passengers' social distancing.

      Mine's the one with an out-of-date bus timetable in the pocket.

        They're 102 parsec away - That's socially distant enough for me...

      Sooo... about 5.6 Kessel Runs? (8.5 in the Falcon measurement system).
