Everyone,


Earth's 'Home' In Milky Way Much Bigger Than Previously Thought, Astronomers Say



(Left) Old picture: Local Arm a small "spur" of Milky Way. (Right) New picture: Local Arm probable major branch of Perseus Arm.


Trigonometric Parallax method determines distance to star or other object by measuring its slight shift in apparent position as seen from opposite ends of Earth's orbit.

The universe wastes nothing, it's simply transferred.

I suppose this means there are more stars in the general vicinity that could have candidate planets in the search for habitable worlds.

Prime Galactic Real Estate.. went up with the finding yesterday. Habitable worlds, think there are just a few, doubts we could live on one. Let alone getting there.

I totally agree. We aren't going even to the nearest star anytime soon. So I guess the main justification in the search is to eventually find ET.
