Hubble Space Telescope measured the "ladder to heaven".

<P Align=center> </ P> World Scientific reports [tech.] Message: believe in science knows that, astronomers can not find in any case the ladder to heaven, but the recent NASA Hubble Telescope .seemed to see such a spectacular human beings, it shows the pictures taken in a "dying" of stars surrounding the structure of the nebula around the ladder. .<P> Scientists often called the Red Rectangle nebula nebula such as astronomical telescopes from the ground and looked, it presents a rectangular structure, color is red. .However, due to cover the atmosphere, scientists from the ground telescope observations of the nebula was a lot of restrictions, and the Hubble telescope will allow scientists to see images of the nebula previously unknown number of new features. .</ P> <P> Hubble telescope images show the red rectangle nebula is not a rectangle, in fact, it presents an X-shaped structure, scientists believe that this phenomenon is due to constitute the core of the star caused by volatile gas and dust .. .Out of the volatile gas in two directions opposite to the stars, jet, and ultimately we see this kind of ice cream similar to cutting-edge connected with the two X-shaped structure. .Of greater concern is that in the stars took on a ladder around the structure, making the nebula looks like a spider web, this shape of the nebula in the known unique. .</ P> <P> life stars of the nebula center of the sun is almost the same, but it has reached the end of life. .The star's outer material essential to the outside world began to form the nebula now, volatile early as 14,000 years ago, the process has already begun. .Then a few thousand years, the star will become increasingly smaller and more heat, and began production of UV radiation around the nebula. .Then the gas in the nebula will be reflected in the fluorescence, it also from the Red Rectangle nebula into a planetary nebula. .</ P> <P> but at the moment of the star's temperature is not high enough, so surround around it will not light the gas atoms, molecules and dust surrounding the reason why is because they can be seen reflected stars given .light. .Part of the gas molecules in the nebula of dust mixed with the universe, transmitting red light, so we see it as red. .In the end is still not sure what type of gas molecules produced a red light, but scientists believe is most likely to come from the star core volatile hydrocarbons. .</ P> <P> taken by the Hubble Telescope to analyze high-resolution images, scientists also found that the central star runs through a dark band. .Scientists say that the dark band around the star's disk of dust from the dense shadow cast, in fact, we can not directly see the light from stars, we see that the dust disk in scattered light. .Astronomers also found that the core of the nebula is actually a pair of companions, each period of revolution of stars is 10.5 months. .</ P> <P> 70s of last century, scientists have found rocket carrying a strong infrared radiation source, and eventually discovered the Red Rectangle nebula. .It is about 2,300 light years from Earth in the direction of Monoceros. .</ P> <P> </ P> <P align=left> </ P> </ p>.
