Supernova

Scientists have created a new image of the tattered remains of a supernova explosion in our galaxy using Nasa's Hubble space telescope.

“It's all that's left of a star that went supernova 340 years ago, collapsing from the weight of its own gravity, then bursting in a sometimes galaxy-obscuring flash. This was followed by the expansion of its remnant materials—shown here in green (oxygen), red and purple (sulfur), and blue (hydrogen and nitrogen).

Centuries after the Cas A explosion, its gases are still on the move. Comparisons of Hubble images taken at different times reveal that some of the debris is traveling up to 31 million miles an hour (50 million kilometers an hour)—fast enough to go from Earth to the moon in 30 seconds.”

Awesome.

    Yes Caz.. Cas IS awesome, eh?
    Scientists reckon that our sun will go nova in about a million years.
    Thankfully we will all be long gone
    by then!

  3. Song for Cas .. CAZ! Hmm or should that be song for Caz Cas..

    How many special people change?
    How many lives are living strange?
    Where were you while we were getting high?
    Slowly walking down the hall
    Faster than a cannonball
    Where were you while we were getting high?
    Someday you will find ne
    Caught beneath the landslide
    In a champagne supernova in the sky.
    Someday you will find me
    Caught beneath the landslide
    In a champagne super nova in the sky
    Wake up the dawn and ask her why?
    A dreamer dreams, she never dies
    Wipe that tear away now from your eye
    Slowly walking down the hall
    Faster than a cannonball
    Where were you while we were getting high?
    Someday you will find me
    Caught beneath the landslide
    In a champagne supernova in the sky.

  5. I like that idea Kath:

    "In a champagne supernova in the sky"

    I like to think we all end up back there some day, everything comes from star dust, and that's where we return.

    Silly notion, but I'm sticking with it.

    "Bought" a star for my brother when he died, well, the naming rights, but I like to think I own that star - my brother's star.

    Few years later bought my daughter a star too, for Christmas, so she already has a star forever, to guide her through life.

    Lost another relative today, only 54 years, sad, too sad. They keep dying.

    Champagne and star dust, could there possibly be a better combination?

    Cheers!

  6. Yeah Caz .. It is sad... Just lost my good friends husband to cancer... Only 48 yrs old. Saddest thing though ,mate , was that he had a young family. Youngest is 3yrs old.

    Champagne and stardust eh??
    Sounds allright to me mate!

  7. That bites Kath, such an awful loss.

    The thing is, you hear these things almost daily. I'm beginning to think that someone is lying to us about the "average" life expectancy. Not kidding, you know, everyday someone still young dies out of the blue from something, or someone is diagnosed with a serious illness.

    I think we should just have another champagne Kath, sit back, look at the stars, and hope for the best each day.

  8. Yeah it's a strange thing CaZ.. My husbands brother died of stomach cancer at the age of 48 too!

    At the time 7 yrs ago prior to his death he implored my husband and me to try for another baby( we had just lost a child at 6 months prem birth to anencephaly)." And if you have a boy you can name him after me" he said
    We took his advice and I gave birth to a healthy.. autistic boy . Whom we named Mark... after his Uncle Mark.. Who coincidentally we later realized .. was autistic too!

    Ain't life strange......
