New image shows Triangulum Galaxy (M33) is bigger than thought

Spitzer infrared images show Triangulum's dust extends way past it's
main disk. Triangulum is part of our Local Group of galaxies cluster, so
it's likely going to merge with us at some point in time.

A downright impressive composite image.

We need at least UVa to SWIR before counting galaxies and stars, and
UVc to LWIR would certainly be best. A bandpass of Gamma to FIR
should cover most everything except black holes.

Nor Dark Matter, either. :-)

Yes, dark matter and/or dark energy (pure electrons or antimatter
positrons), as being the cosmic soup of the day that's keeping photons
from going 2c or faster.

I have no idea what you're talking about.

Have you or anyone else ever seen an electron or a positron? (didn't
think so)
