The Hubble Space Telescope captured this image of a dying star casting off layers of gas and dust, leaving the burned-out white dwarf star, the bluish-white dot in the centre. The star, NGC 2440, is about 4,000 light years away from Earth. (Associated Press/NASA, European Space Agency, and Keith Noll of the Space Telescope Science Institute) A Canadian astrophysicist has used the pulsations of a white dwarf star to determine how it spins, raising new questions about the life, and death, of stars. Gilles Fontaine of the University of Montreal and his colleagues in Canada and France used a technique called astroseismology to map the inside of a white dwarf. White dwarfs are the dying embers of collapsed stars that are slowly cooling and fading away.
"Because the red giants are so big, the gravity at their surface is quite low, making it easy for matter to escape," said Fontaine in an email. Stars have a large mass and they all spin, which means they all have a lot of angular momentum. Feather & Hammer Drop on Moon. The Nine Planets Solar System Tour. You Tube - Animaniacs universe song.

Secret Worlds: The Universe Within - Interactive Java Tutorial. Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode.
