THE BARGE AND THE PEANUT - NGC 6745 - HOW YO-YO'S ARE FORMED |
|---|
No wonder
Hubble left it
out there is hardly
anything there. It is very
small, get out your magnifying
glass you can't miss it. How can a
bacteria confronting a water lice do
so much damage to a soft bodied life
form. Is it possible the bacteria
sailed in an arc only over the
upper edge, creating the
yo-yo arm, and the
broadside swipe
was from
before
Looking
like a yo-yo,
with two long thin
arms winding outer circle
parallel paths, this galaxy has
the likeable feature of showing us a
very nice example of yo-yo arms in
a galaxy, which are commonplace,
for instance yo-yoes are
obvious in the
Stephans
group, and
a new yo-yo seems
to have just been formed in Ngc 6745
NGC 6745 WITH A BRAND NEW YO-YO ?
Two yo-yo's - the lower one interrupted
It appears
the barge (big)
was closer in forground
space when the encounter event
first initiated with the dingy making
contact in rearspace at the upper left, as
the dingy continued to more around the rear flank
of the barge the barge was slowly drifting backward,
causing the thin band of excitement to gradually
narrow closing toward the main body and
as it happens left the event when
reaching the right tip of
the barge the two
now drifting
apart the
barge
drifting
rearward the
dingy drifting to
the right and continuing
slowly forward. This logically
seems to explain why the gap is wider at
the upper left of the barge where the yo-yo starts
and the dingy has actually drifted in on an arc over the barge.
As for deep space motions, more than one view is possible -
the barge is faster moving and came in from the
lower right heading west, clipping past
the dingy. The dingy is faster
moving coming on in
from the
upper rear
left clipping fast
past the barge in a forward
pass - both are also possibles, in lack
of a larger deep space view to see the whole situation

From the Hubble images page
This Ngc 6745 collision event shows a streaming long tail still connected
to the departing small galaxy that was cause of a new
'yo-yo' restructure to the large cigar shaped galaxy.
More Ngc 6745 are here
and here.
