An invisible Man in the sky who has been around for ever, who cares passionately about a third rate American Football quarterback, but condemns millions of children to death because they were born into the wrong religion?Ī supreme being that left us a "Book" that has no instructions for how to accomplish anything of use, like maybe the explanation of logarithms, or calculus, but instead it tells us that Adam and Eve had two sons, one of whom killed the other which leaves Adam, Eve and one of their sons. If you think the Big Bang is too complicated to have created the Universe, then exactly how complicated would a "God" have to be to create it? Infinitely more complicated than any other explanation for a Universe coming into existence and exponentially more improbable. "It still is an active area of research." "Were they thrown out by the star as it expanded, or have they formed in the cloud of gas somehow through some instability, like forming clouds in the sky? Perhaps it's an equivalent sort of process," Walsh said. One of the mysteries is how these cometary knots originated. Their shape is a little bit like a comet, but they're not comets. These clumps of gas and dust endure despite the high-energy radiation coming from the dying star. Unlike in visible-light images of the Helix nebula, this one reveals its cometary knots, which are strands of hydrogen that can be as big as our solar system.
The gas in the nebula is mainly hydrogen, with about 10% helium and 1% other elements, Walsh said. "It’s a great target for the VISTA telescope because it has a big field, it can cover a large part of the area of the sky," Walsh said. Telescopes that capture only visible light have not been able to get such a detailed view of the nebula. This image shows the nebula in the infrared light spectrum, which is invisible to the eye and more toward heat radiation. The star at its center is evolving to become a white dwarf. It's quite large - its main ring is 2 light-years across, although its material spreads out to 4 light-years. The Helix nebula resides in the constellation Aquarius about 700 light-years away. The star heats up and lights up the nebula, which refers to the molecular gas, ionized metal and dust around it. Rather, it forms like this: As a star ages and gets larger, the gas that surrounds it starts to get blown off into a large, fuzzy ball of gas. It's the best image yet of the Helix nebula, said Jeremy Walsh, a scientist at the European Southern Observatory in Germany.Ĭontrary to its name, a planetary nebula does not include a planet. Using infrared light filters, scientists have colored the image to reflect the spectrum of radiation from the nebula. The image comes from the VISTA telescope, the world's largest survey telescope, at the Paranal Observatory in Chile.
Astronomers now have their most detailed view yet of the Helix nebula, one of the closest planetary nebulae to Earth.
