Explanation:
What's happening at the center of our Milky Way Galaxy?
To help find out, the orbiting
Hubble and
Spitzer
space telescopes have combined their efforts to
survey the region in unprecedented
detail in infrared light.
Milky Way's center
because visible light is more greatly obscured by
dust.
The above image encompasses over 2,000 images from the
Hubble Space Telescope's
NICMOS taken in 2008.
The image spans 300 by 115 light years with such high resolution that structures only 20 times the size of our own Solar System
are discernable.
Clouds of glowing gas and
dark dust as well as three large star clusters are visible.
Magnetic fields
may be channeling
plasma
along the upper left near the
Arches Cluster,
while energetic
stellar winds are carving
pillars near the
Quintuplet Cluster on the lower left.
The massive Central Cluster of stars surrounding
Sagittarius A*
is visible on the lower right.
Why several central, bright, massive stars appear to be unassociated with
these
star clusters is not yet understood.
