No strain for Andromeda: Galaxy is cosmic cannibal


Written by Seth Borenstein

"Our nearest major galactic neighbor is a cosmic cannibal. And it's heading this way eventually. Astronomers have long suspected Andromeda of being a space predator, consuming dwarf galaxies that wander too close. Now, cosmic detectives are doing a massive search of the neighborhood and have found proof of Andromeda's sordid past: They've spotted leftovers in Andromeda's wake."

"Early results of a massive telescope scan of Andromeda and its surroundings found about half a dozen remnants of Andromeda's galactic appetite. Stars and dwarf galaxies that got too close to Andromeda were ripped from their usual surroundings."

"What we're seeing right now are the signs of cannibalism," said study lead author Alan McConnachie of the Herzberg Institute of Astrophysics in Victoria, British Columbia. "We're finding things that have been destroyed ... partly digested remains."

"Their report is published in Thursday's edition of the journal Nature."

"Andromeda and our Milky Way are the two big dogs of our galactic neighborhood. Andromeda is the closest major galaxy to us, about 2.5 million light years away. A light year is about 5.9 trillion miles. The massive mapping of Andromeda is looking half a million light years around Andromeda".
"
Astronomers have known for decades that galaxies consume each other, sometimes violently, sometimes just creating new mega-galaxies. But this study is different because "of the scale of the cannibalism and we've found evidence directly in front of our eyes," said co-author Mike Irwin, an astrophysicist at the University of Cambridge in England."

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.
