  • Planet made of Diamond discovered?

    Believe it or not, NASA astronomers say they found a planet made of diamond.
    According to them this planet was formed by it's dead parent star.
    The planet orbits a pulsing neutron star, in which appears to caused the carbon within the planet to crystallize.

    Neutron Star's are stellar remnant that can result from the gravitational collapse of a massive star during a Type II, Type Ib or Type Ic supernova event. Such stars are composed almost entirely of neutrons, which are subatomic particles without electrical charge and with a slightly larger mass than protons. Neutron stars are very hot and are supported against further collapse by quantum degeneracy pressure.

    A newly discovered alien planet that formed from a dead star is a real diamond in the rough.

    The super-high pressure of the planet, which orbits a rapidly pulsing neutron star, has likely caused the carbon within it to crystallize into an actual diamond, a new study suggests.

    The composition of the planet, which is about five times the size of Earth, is not its only outstanding feature.

    The planet's parent star is a special kind of flashing star known as a millisecond pulsar, a rapidly rotating neutron star formed from a supernova. The entire system, which is only the second of its kind ever discovered, is located about 4,000 light-years from Earth in the constellation of Serpens (The Snake).

    A gem of a find

    Seventy percent of millisecond pulsars found have a companion, which provides additional energy to ramp up the pulsars' rapid rotation. Generally, this companion is a dying star called a white dwarf; more than 180 millisecond pulsars have been found with white dwarfs over the years.

    Theonly planet known to be orbiting in such a system was detected in 1992 — until now."The pulsar was found in December 2009," lead scientist Matthew Bailes of Swinburne University of Technology in Melbourne, Australia, told SPACE.com via email."We've been on the trail of the companion ever since."



    This illustration shows the alien planet around pulsar PSR J1719-1438, where ultra-high pressures caused carbon to crystallize in the remnant of a dead star. The planet is made of diamond and orbits a dense pulsing star with a radius smaller than that of our sun.

    From the ashes of a supernova

    Known as PSR J1719-1438, this particular pulsar completes more than 10,000 rotations in a minute. Tiny and compact, it's only about 12 miles (20 kilometers) across, but it has a mass that is 1.4 times that of our sun.

    PSR J1719-1438 transformed from an average star to a radio pulsar when a dying star in a binary system exploded. The compact core of the star formed with a very high rotation speed from the ashes of the supernova.

    When the second star in the system reached the end of its life, it expanded as a red giant and finally morphed into a white dwarf. The pulsar began to suck mass off its companion, causing the pulsarto spin faster and faster until it attained its breakneck speed.

    From dying star to diamond planet

    What happened next depends on the system. Most white dwarfs continue to orbit the new millisecond pulsar, but some are consumed by it.

    "The fate depends upon the mass of the white dwarf and how far it is from the pulsar," Bailes said.

    If it is both close and massive, the two spiral together. Astronomers assume this is what happened to the 30 percent of millisecond pulsars found without a companion.

    In the case of the diamond planet, astronomers think that the core of the white dwarf failed to merge completely with its companion.

    "When they got very close, the star lost a lot of its matter and moved out to its safe distance of about a solar radius," Bailes said.

    Now tiny, having lost more than 99.9 percent of its original mass and no longer engaged in the fusion reactions that drive a star, the dead core is classified as a planet.

    Ironically, the star-turned-planet is larger than its sun. With a diameter of about 37,300 miles (60,000 km), it's five times the size of Earth, but 3,000 times larger than the millisecond pulsar it orbits.

    The planet itself orbits the pulsar in a little more than two hours. The entire system would fit within the diameter of our sun.

    The research was published online in the Aug. 25 edition of the journal Science.

      Nope, I actually saw this on Space.com mid day yesterday.

        Well pin a rose on your nose lol

        Yahoo had this one and the other one you posted about the soldier with the dog. Thought it was an answer to a coincidence.

          Nah. I was checking my email when I came across the soldier with his dog.
          That was just a coincidence, and I thought it was something worth posting.

          I'm the forums Astronomy junky, I normally post articles from NASA and Space.com often.

          That's where most of my CP's come from. And it would explain why someone CP'ed me a picture of the Universe.

            Nice. Can't say I've been photo bombed in a CP by the entire universe. Must have been a really big camera

              Just picture this photo 20x bigger, and covering your entire screen.

                      Insane23 do you ever listen to the Astronomycast podcast? You can find it on Universetoday.com.

                      It's an aswome podcast and they cover lots of cool topics. They talked about diamond stars being a possibility awhile back (I can't remember the date but it was awhile ago). It's cool that they've actually found one.

                      Thanks for sharing the link, I love your science posts

                        Thanks, I really appreciate it. I haven't been posting them lately, because I normally post something that people would find interesting, not just what I find interesting.

                        I get a lot of articles and stories everyday, I just don't post em, because of that fact that I don't know if people would be interested.
                        So once more thank you.

                        I never heard of that podcast, I'll check it out and listen to it. Most of the stuff I post come from newsletters.

                          Blood Diamond 2, perhaps?
