    Todays piccy is of something that I enjoy looking at most of all, a nebula; this is the Stingray nebula the youngest known planetary nebula.

    I hpoe you folks take as much pleasure from looking at this as I do.



    This Wide Field and Planetary Camera 2 image captures the infancy of the
    Stingray nebula (Hen-1357), the youngest known planetary nebula.

    In this image, the bright central star is in the middle of the green
    ring of gas. Its companion star is diagonally above it at 10 o'clock. A
    spur of gas (green) is forming a faint bridge to the companion star due
    to gravitational attraction.

    The image also shows a ring of gas (green) surrounding the central star,
    with bubbles of gas to the lower left and upper right of the ring. The
    wind of material propelled by radiation from the hot central star has
    created enough pressure to blow open holes in the ends of the bubbles,
    allowing gas to escape.

    The red curved lines represent bright gas that is heated by a "shock"
    caused when the central star's wind hits the walls of the bubbles.

    The nebula is as large as 130 solar systems, but, at its distance of
    18,000 light-years, it appears only as big as a dime viewed a mile away.
    The Stingray is located in the direction of the southern constellation
    Ara (the Altar).

    The colors shown are actual colors emitted by nitrogen (red), oxygen
    (green), and hydrogen (blue). The filters used were F658N ([N II]),
    F502N ([O III]), and F487N (H-beta). The observations were made in March

    A larger image of this piccy is available here, be warned it is very large, IIRC about 15 MB.

    Reminds me of....

    Spookily, it reminds me of the last thing I saw before I had a cardiac arrest after a party one night. After losing 6 pints of blood through my stomach wall I was brought back to life with transfusions and machines and paramedics and things.

    No, seriously.

    I'll never touch Martini again.

    Nice, I think I'll avoid the high-res one as I fear I may break my modem. :D
    The scale of that image is just fantastical... 130 solar systems large, that's one mighty bubble of gas. The universe doesn't work in halves! :)
