  • Hubble image captures the death of a star

    Image

    Feb. 3 (UPI) -- A new image from the Hubble Space Telescope displays the beauty of a stellar death -- in this case, the death of a low-mass star, similar to our sun in size.

    Once a red giant, the star is currently in a transitionary phase: It's on its way to becoming a planetary nebula. The Hubble image reveals the star's layers of gas and dust being shed and thrown outward. The expelled material, now forming clouds, could eventually form new stars and planets.

    Astronomers rarely catch dying red giants in their transitionary phase. It will only be a few thousand years before the star is a pure planetary nebula -- a blip in space time.

    By then, the spent stellar material will have slowed down and taken on more convoluted shapes. As the Hubble shows, the streams of gas are still energy filled and direct. The waves of yellow gas seen in the image are traveling at speeds of 621,371 miles per hour.

  • This is awesome, and so is astrophysics.

    I can't wait until we get that new telescope up there.

    Yes, astrophysics is indeed awesome! I'm a Pisces - what sign are you? :) :)

    Seriously, I have an email friend in Montreal who is an astrophysicist, and she gets asked about ASTROLOGY crap all the time. Drives her nuts! I've got an unrelated story she told us about on an invitational email list, which I'll have to put up on the Shack... ;)
