    Mostly not visible from the Americas. Too bad.

    The CHIME radio telescope operates in remote British Columbia, far from civilization’s incessant electronic thrum.


    Not +that+ remote! I even heard of a guy near here who is going to get indoor plumbing installed next year.

    I suspect the real sticking point is evolving from complex life to intelligent (symbol-using) life. And then surviving technological and environmental disaster.

    I suspect the survival rate, eeyore quality of life in general, with an absence of significant technology, would not be so great.

    This massive and exceptionally bright blue star was hypothesized to exist based on astronomical observations made between 2001 and 2011, but as of 2019, it is no longer detectable.


    Wouldn't that mean it is hypothesised to have disappeared?

    The sun, 10 year time-lapse.

    SDO is still my favorite satellite.

    And old Sol my favorite star. Even if he gets a little crotchety in middle age. As long as his flares don't start flaring up much we'll be all right.

    Every once in a while in there you see a starquake that ripples across large areas. That is pretty scary to me, even more than the occasional X-class flare. It is as if just a little more shaking would cause the whole thing to fall apart.

    It's a fail-safe design. It falls together.
  20.  
    So they say. But I think we have decided that the centre of the sun is a zone of null-g and it is only pressure that holds it together down there. Should a starquake be energetic enough and at the resonant frequency of the fusion shell, the thing could shatter like a wineglass as the fat lady sings.

    No, I know it probably can't happen that way, but it would make for some neat CGI effects in a movie.
