" Hubble Sees Red Giant Blow a Bubble
Camelopardalis, or U Cam for short, is a star nearing the end of its life. As stars run low on fuel, they become unstable. Every few thousand years, U Cam coughs out a nearly spherical shell of gas as a layer of helium around its core begins to fuse. The gas ejected in the star’s latest eruption is clearly visible in this picture as a faint bubble of gas surrounding the star." (NASA IMAGE OF THE DAY - July 6th, 2012 - www.nasa.gov/multimedia/imagegallery/image_feature_2302.html)Young stars are also unstable ! This is exactly at the heart of Dr Herndon's theory of an eruptive solar event swept the inner solar system clear of gas giant ATMs and rocky debrie. Attachments:

Now imagine what our solar system would look like if the eruptive events boundary (outermost limit) was approximately our asteroid belt. All the inner planets are swept clear of ATMs ! Mercury, Venus, Earth, and Mars. Most of the heavier and problematic debris (things that caused all the impact craters on the earth and moon) were swept away as well - possibly being left behind as the asteroid belt - or a part of it) Not only could this even have ripped our ATM away, but also threw the asteroid that supposedly killed all the dinosaurs. Earth expanded All the planets outside of the asteroid belt remain gas giants! Attachments:

It is too bad that we dont know more about other solar systems to compare with.

An intriguing spiral structure surrounding a pulsing red giant star may be offering a preview of how the sun will behave at the end of its life. Using the Atacama Large Millimeter/Submillimeter Array (ALMA) in northern Chile, an international team of astronomers found the spiral structure, one never seen before, in the envelope of gas and dust around a red giant about 1,000 light-years from Earth and took a detailed three-dimensional reading of its composition. The spiral is thought to be created from the gases being expelled by the dying red giant called R Sculptoris. The structure provides information about the velocity of the wind blowing off of R Sculptoris, revealing that the star has expelled three times as much mass as previously estimated. "We can 'walk along' the spiral and use it as a clock to see what happened when," said Matthias Maercker, of Germany's University of Bonn. www.foxnews.com/science/2012/10/10/strange-star-spiral-offers-clues-to-sun-fate/#ixzz28wjhxOmHEven tho this is evidence from a dying star, it is still evidence of a circular clearing formed by an eruptive solar event.Attachments:
