The Milky Way Is Devouring the Alien Sagittarius Dwarf Galaxy

“After slow, continuous gnawing by the Milky Way, the Sagittarius Dwarf galaxy has been whittled down to the point that it cannot hold itself together much longer. We are seeing Sagittarius at the very end of its life as an intact system.”

– Martin Weinberg, Ph.D., Univ. of Massachusetts

August 3, 2007  Charlottesville, Virginia – More and more people are depending on the internet for their daily news updates. But there is no overall Web Editor to do a reality check on content. So, finding out what is factual is an ever-increasing challenge.

One headline that has been circulating on the web since June 2007 is false, according to astronomers. It states:  “Scientists Prove We Are Not From Here!” The author is listed as Dan Eden of Viewzone.com. Mr. Eden begins:

“Imagine the shock of growing up in a loving family with people you call ‘Mum’ and ‘Dad’ and then, suddenly, learning that you are actually adopted!

“This same sense of shock came as scientists announced that the Sun, Moon, our planet and its siblings, were not born into the familiar band of stars known as the Milky Way galaxy, but we actually belong to a strange formation with the unfamiliar name of the Sagittarius Dwarf galaxy.”

The article references astrophysicists at the University of Virginia who used the Two-Micron All Sky Survey (2MASS) to survey the sky in infrared light.

The faint extension below the Milky Way center is the core of the Sagittarius Dwarf galaxy. The objects in the lower right quadrant are the Large and Small Magellanic Clouds, which are more intact satellite galaxies of the Milky Way than the Sagittarius Dwarf that is being torn apart and absorbed by the Milky Way.

According to Dan Eden, the University of Virginia astrophysicists confirmed:

“The fact that the Milky Way is seen in the sky at an angle has always puzzled astronomers. If we originated from the Milky Way, we ought to be oriented to the galaxy’s ecliptic, with the planets aligned around our Sun in much the same angle as our Sun aligns with the Milky Way. Instead, the angle suggests that our Sun is influenced by some other system. Now we know what it is. We actually belong to the Sagittarius Dwarf galaxy.”

University of Virginia Astrophysicists Never Said Our Solar System from Sagittarius Dwarf

I called the University of Virginia Astronomy Department and talked with Prof. Steven Majewski, lead author of a paper published in the Astrophysical Journal entitled: “New Map of the Milky Way Shows Our Galaxy to Be A Cannibal.” The date of that paper?  December 20, 2003 – four years ago!

The Astrophysical Journal article was about how the Sagittarius Dwarf galaxy is 10,000 times smaller than the mass of our Milky Way and is being absorbed by the Milky Way – a common process in this universe where larger galaxies “eat” smaller ones and grow bigger.

Prof. Majewski and his colleague, Prof. Michael Skrutskie, explained that our solar system and Milky Way only briefly and periodically pass through Sagittarius debris. And one of those times happens to be now.  “Remarkably, stars from Sagittarius are now raining down onto our present position in the Milky Way. Stars from an alien galaxy are relatively near us.”

In the Astrophysical Journal article, the scientists do not say our solar system is from the Sagittarius Dwarf galaxy. Further, astrophysicists know that our solar system and others have evolved at many different angles to the Milky Way galactic plane.

Bottom line:  a 2003 science journal article gets resurrected four years later in 2007 with the sensational claim that our solar system is not really from the Milky Way – while in fact, the original science was about how the Milky Way, that includes our solar system, is big enough to eat other smaller galaxies.
