Article: A "new look" for our Milky Way Galaxy

Based on data from Spitzer. Wow, if that IS what our Milky Way Galaxy looks like...! Majestic, exquisite...incredible.

They're fairly certain our Galaxy contains a central bar which is 27,000 l/y long (7,000 l/y longer than previously believed). The bar seems primarily populated by "old and red stars" (red giants).

QUOTE
It also shows that the bar is oriented at about a 45-degree angle relative to a line joining the sun and the center of the galaxy.


Article discusses the methods/processes involved in building up such a "portrait."

QUOTE
With the help of NASA's Spitzer Space Telescope, astronomers have conducted the most comprehensive structural analysis of our galaxy and have found tantalizing new evidence that the Milky Way is much different from your ordinary spiral galaxy.


Yep, I'm biased...but honestly, if that IS what our MWG looks like I must say it's the most beautiful yet "seen." All those incredibly long swirling arms around that huge central bar. smile.gif
