    A cosmic cardiodolia!

    An Embiggened Heart – now showing at a universe near you.

    Awesome – it even has the fatty tissue. :) Now if it would only morph into the shape of a real heart. I wonder what the origin of the ‘valentine heart’ shape is – I’ve always thought of it as a red sheep’s scrotum as seen while doing a handstand. Having had to kill and clean my meals since I was about 8, I never could associate that shape with a heart. I’ll shut up now – that’s too much reality from me for the moment.

    Argh! It’s a skull! Complete with blue sparkle in the empty eye socket (cough cough Terry Pratchett cough) … ūüėČ

    Oh, sorry. Valentine. Not Halloween. Uh, yes, it’s totally a heart. Awww. Sweet.

    (Skull, I say! Skull!)

    @Mark: You’re right! It’s an alien skull with a shining eye – a bit like the terminator, but with an alien head of course and the eye shines blue rather than red. That also accounts for the top of the head resembling buttocks – it’s obviously ET. I don’t know how I missed that …

    Happy Valetines day
    (On bit of a sugar high now.)

    The APOD for February 14 is of the “Heart Nebula” which looks a lot more like an actual heart and less like the traditional “heart shape.”

    Cute. :-)

    But er .. what is it?

    Usually the BA tells us a lot more about what we’re seeing ..

    Is it a close up of a planetary nebula somewhere via HST?


    Juniper from Jupiter, click on the link below the picture to find out.

    Maybe it’s the state of my sex life right now, but I really don’t see the “heart” here… actually I see the upper half of a red lit skull… (too many years into heavy metal, I guess.)

  11. Joe Meils

    Oh well, you know what they say… “Sex & death…”

  12. Juniper from Jupiter

    Aha! THX IVAN3MAN. Belated, I know but thanks all the same. :-)

    Oops, I missed that link (& then I’ve been away for a few days so quite a bit still to catch up on here ..)

    Okay so the BA did tell us elsewhere :

    “W5 is a nebula, a giant cloud of gas roughly 6000 light years away in the constellation of Cassiopeia. It‚Äôs enormous, spanning about 2 x 1.5 degrees of the sky (15 times the size of the full Moon on the sky), and is actively cranking out stars. The valentine-shape is actually an enormous cavern, a hollow carved out of the gas by the winds and fierce ultraviolet light flooding out from massive young stars in its‚Ķ well, its heart. It‚Äôs like these stars are blowing a vast bubble in the middle of the cloud.”

    Neat! 8)
