FAST GAS BULLET FROM COSMIC BLAST N49
Art gallery?
Who needs it?
Look up at the swirling silver-lined clouds
in the magnificent blue sky
or at the silently blazing stars at midnight.
How could indoor art be any more masterfully created
than God's museum of nature?

What is that strange blue blob on the far right? No one is sure, but it
might be a speeding remnant of a powerful supernova
that was unexpectedly lopsided. Scattered debris from supernova explosion N49
lights up the sky in this
gorgeous composited image based on data from the Chandra and Hubble Space
Telescopes. Glowing visible
filaments, shown in yellow, and X-ray hot gas, shown in
blue, span about 30 light-years in our neighboring galaxy, the Large Magellanic Cloud.
Light from the original exploding star reached Earth thousands of years ago,
but N49
also marks the location of another energetic outburst - an extremely
intense blast of
gamma-rays detected by satellites about 30 years ago on 1979 March 5. The
source of the March 5th
Event is now attributed to a magnetar
- a highly magnetized, spinning neutron star also born in
the ancient stellar explosion which created supernova remnant
N49. The magnetar,
visible near the top of the image, hurtles through the supernova debris cloud at
over 70 thousand kilometers per hour. The blue blob on the far right, however,
might have been expelled
asymmetrically just as a massive star was exploding. If so, it now appears
to be moving over 7 million kilometers per hour.
I can't restrain my chuckles when I read discussions aboiut a 'strange blue blob on the far right' !!
I am so taken with the magnificent image of this galaxy that the blob feels to me like just that - a little blob of blue off to the side.
And yet, in rereading the explanation, I am struck by the miracles of astornomical research that enable us to make these speculations.
Our right and left brain hemispheres each have their own focus and understandings of the universe. How wonderful to be able to enjoy both sides!
