Astronomers catch new views of superstar





It has been announced at several news and astronomy websites (such as: http://www.ctv.ca/) that scientists have been able to use a very large telescope to get new views of the second-brightest star in the constellation of Orion,a star named Betelgeuse.

As large as our own sun is, Betelgeuse is 1,000 times larger that that.Betelgeuse is so huge that, if it replaced the Sun at the center of our Solar System, its outer atmosphere would extend past the orbit of Jupiter.According to
the wikipedia.com, "Betelgeusese is a a semiregular variable star located approximately 640 light-years away from Earth. ( A light-year or light year (symbol: ly) is a unit of length, equal to just under 1013 kilometres. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year.) A semiregular variable star is a star which is a giant or a supergiant with a large radius and luminosity."

Astronomers believe Betelgeuse is only a few million years old. (source:http://en.wikipedia.org/wiki/Betelgeuse)The name Betelgeuse is a corruption of the Arabic "yad al jauza," which means the "hand of al-jauza," al-jauza the ancient Arabs' "Central One," a mysterious woman. (source:http://www.astro.illinois.edu/~jkaler/sow/betelgeuse.html).

Betelgeuse is the 12th brightest star in the sky, however it appears to have decreased its diameter by more than 15 percent since 1993.It is now estimated to be located around 430 +/- 100 light-years from Sol.It lies in the northeastern part (5:55:10.3+7:24:25.4, ICRS 2000) of Constellation Orion.Like many of the stars of Orion, it was probably formed a few million years ago from the molecular clouds observed in Orion but has evolved rapidly due to its unusually high mass. Betelgeuse is surrounded by shells of dust and gas that it has already blown off through a very strong stellar wind. (source:http://www.berkeley.edu/news/media/releases/2009/06/09_betelim.shtml)


The image of Betelgeuse used in this blog entry was taken by the Hubble Telescope.

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed



Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia



A person's true wealth is the good he or she does in the world. - Mohammed



Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein



The best way to find yourself, is to lose yourself in the service of others. - Ghandi



The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller



Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns



Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama



Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -



Milan Kundera, The Unbearable Lightness of Being



The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
