Waspie_Dwarf Posted May 10, 2014 #1 Share Posted May 10, 2014 (edited) Astronomers Find Sun's "Long-Lost Brother," Pave Way for Family Reunion AUSTIN, Texas - A team of researchers led by astronomer Ivan Ramirez of The University of Texas at Austin has identified the first "sibling" of the sun — a star almost certainly born from the same cloud of gas and dust as our star. Ramirez's methods will help astronomers find other solar siblings, which could lead to an understanding of how and where our sun formed, and how our solar system became hospitable for life. The work appears in the June 1 issue of The Astrophysical Journal."We want to know where we were born," Ramirez said. "If we can figure out in what part of the galaxy the sun formed, we can constrain conditions on the early solar system. That could help us understand why we are here." Read more...

aka CAT Posted May 10, 2014 #4 Share Posted May 10, 2014 When the orbits of sun and HD 162826 are run backward to their birthplace, a Happy Birthday song will be in order. Thence, the brother of the sun could stand a nickname. Being that he's in the constellation Hercules, :-? maybe "Happy Birthday Herculean Dude and his brother, Happy Birthday to you..." 1 Link to comment Share on other sites More sharing options...
taniwha Posted May 10, 2014 #5 Share Posted May 10, 2014 What has this got to do with the "rare earth hypothesis"? The rare earth hypothesis describes the perfect place that a earth type planet might form and life can evolve. The milky way matches the hypothesis. And yet here we are. 1 Link to comment Share on other sites More sharing options...
Waspie_Dwarf Posted May 12, 2014 Author #6 Share Posted May 12, 2014 The rare earth hypothesis describes the perfect place that a earth type planet might form and life can evolve. The milky way matches the hypothesis. And yet here we are. Despite the fact that I explained it in very simple terms you really don't understand the "Rare-Earth" hypothesis at all. The "Rare Earth" hypothesis is exactly what it's name suggests, a hypothesis that says planets like Earth are rare. It sets out a series of conditions which limit the probability of life existing else where in the Universe. These conditions are based on the conditions found on Earth. As the Earth is found in the Milky Way galaxy it stands to reason that the Milky Way galaxy MUST have the right conditions to find a planet like Earth. This is not some great revelation you have made here, it's simply a case of stating the bloody obvious. The point of the "Rare Earth" hypothesis is not to say that the Milky Way is suitable for life... we already know that, it's to say that many other galaxies AREN'T. Your statement is like saying that Waspie_Dwarf's cat lives in Waspie_Dwarf's living-room. That means that Wapie-Dwarf's house must have the correct condition's for Waspie_Dwarf's cat.. well d'uh! That goes without saying. However just because the house is the perfect place to find the living room it does not mean that other rooms in Waspie_Dwarf's house MUST have cats. In fact the "Rare Earth" hypothesis would go further, it would say that is not enough to live in Waspie_Dwarf's house, the conditions must be the same as the living-room, hence finding further cats, even in Waspie_Dwarf's house are very unlikely. If you had understood the "Rare Earth" hypothesis you would have understood that a galaxy very similar to the Milky Way is just one of many conditions that need to be met. As usual your comment does nothing except advertise your total ignorance of the subject. As usual you did not answer the question asked which was: What has this got to do with the "rare earth hypothesis"? Since it is virtually impossible to get a straight answer from you on anything I'll answer the question for you... The "Rare Earth" hypothesis has NOTHING to do with the article I posted. Would it be too much to ask that you make on-topic comments? Since there is already a topic where the "Rare-Earth" hypothesis is being discussed I suggest that you use that if you wish to discuss it further. 2 Link to comment Share on other sites More sharing options...

That is a simple way of saying that no two planets are the same, or that life is unique or the Earth is rare same thing. Im not sure if the rare earth hypothesis even takes into account the possibility that We might be riddled with life and Earthlikes in our galaxy alone. Technically of course you are correct so I have come up with my own idea called the Common Earth Hypothesis where the odds of Earth like planets are scattered abundantly through out our Milky Way.

Waspie_Dwarf Posted May 12, 2014 Author #12 Share Posted May 12, 2014 Technically of course you are correct so I have come up with my own idea called the Common Earth Hypothesis where the odds of Earth like planets are scattered abundantly through out our Milky Way. What part of the following was beyond your capacity to understand? Since there is already a topic where the "Rare-Earth" hypothesis is being discussed I suggest that you use that if you wish to discuss it further. And by the way it can only be your idea if you came up with it first, Since the belief that Earth like planets are common has existed for many MANY decades you really can not claim it as your idea. Now, go back and re-read the posts Lilly and I made on the various hypothesis about life through the universe. Read them as many times as it takes for something to sink in. Then, if you have any more comments to make, make them in that thread, not this one.

Frank Merton Posted May 13, 2014 #16 Share Posted May 13, 2014 Two things are pretty wonderful: that they are able to measure the chemical composition so well, especially of extremely rare molecules, and that they are able to trace back the orbit of the star through several galactic revolutions Except maybe for panspermia, I don't think this makes these stars significantly better as candidates for life than other similar stars born elsewhere. They will all be roughly the same age though, which might have a bearing. Link to comment Share on other sites More sharing options...

A great many planets are thought to be ejected or caused to leave their birth system by close encounters in such clusters. comes closest to explaining to me the relationship between globular clusters’ and the sun’s leaving their birthplaces. http://www.unexplain...8 Edited May 14, 2014 by aka CAT Link to comment Share on other sites More sharing options...
Frank Merton Posted May 14, 2014 #20 Share Posted May 14, 2014 The sun seems to have been born in a normal gas cloud evolving into an open cluster and then the stars dispersing because of random motions. That would imply the sun has dozens of siblings, if not thousands, scattered by now all around the galaxy. We are only likely to identify those that are by chance relatively nearby.

aka CAT Posted May 14, 2014 #21 Share Posted May 14, 2014 (edited) Frank et al, Interesting as was my last quote, it was not the one that linked GCs with stars. The sun seems to have been born in a normal gas cloud evolving into an open cluster and then the stars dispersing because of random motions. That would imply the sun has dozens of siblings, if not thousands, scattered by now all around the galaxy. We are only likely to identify those that are by chance relatively nearby. They will find more sibling stars, but, given the process, maybe not that many, e.g."The team identified HD 162826 as our sun’s sibling by following up on 30 possible candidates [...] But several factors are needed to really pin down a solar sibling, Ramirez said. In addition to chemical analysis, his team also included information about the stars’ orbits — where they had been and where they are going in their paths around the center of the Milky Way galaxy. Considering both chemistry and orbits narrowed the field of candidates down to one: HD 162826." Edited May 14, 2014 by aka CAT Link to comment Share on other sites More sharing options...

I wonder if stars born in these clusters also 'hatch' in clusters similar to fish eggs all at the same time or even sub divide like biological cells. I guess these things arent known until we can actually witness one in action. Link to comment Share on other sites More sharing options...
