UGC 8508

A lovely spheroidal dwarf galaxy. Visually, the younger, bluer stars appear near the center, while an older, redder population appears on the outskirts. Interesting. I think this is typical for these spheroidal dwarfs, but I haven't taken much notice to it.

 

I tried to include as much as I could on the right, but unfortunately the nice data is cut off right about there. The galaxy continues more or less symmetrically to the right. Note the IR data did not cover the entire image, so the parts in the upper left and lower left that look kind of yellow and lack red are where that ended.

 

Apparently I already processed this one a while back but I forgot. Well it looks way better with Meredith's data, that's for sure.

 

This was put together using some custom drizzled data made by Meredith Durbin, attribution as follows:

NASA/ESA/Meredith Durbin/Judy Schmidt

 

That data came from these proposals:

ACS Nearby Galaxy Survey

A Calibration Database for Stellar Models of Asymptotic Giant Branch Stars

 

Red: WFC3/IR F110W+WFC3/IR F160W

Green: ACS/WFC F606W

Blue: ACS/WFC F475W

 

 

North is 32.32° clockwise from up.
