APOD: Fast Gas Bullet from Cosmic Blast N49 (2010 Jun 30)

Image Fast Gas Bullet from Cosmic Blast N49

Explanation: 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.

Is the velocity cited along the line of sight or is it proper motion. If the latter, why do we not see any evidence of interaction between the magnetar and the surrounding gas cloud?

A high tech civilization trying to escape the supernova of its home star :)

Here as in the Crab nebula resemble the shape of the exhaust gases by a magnetar, presumably from a neutron star, add or a body composed of neutrons.

The asymmetric rotation "star" makes the gases expand, following the shape is observed.

It therefore should not be excluded that the neutrons do not have a spherical shape as I have seen before now.

Aca como en la nebulosa del Cangrejo se asemejan la forma de los gases expulsados por un magnetar, presumiblemente a partir de una estrella de neutrones, agrego, o de un cuerpo formado de neutrones.El giro asimétrico de la "estrella" hace que los gases se expandan siguiendo la forma que se observa.Es por ello, que no se debe descartar que los neutrones no tengan forma esférica tal como tengo considerado antes de ahora.

May the Blue Blob not be an event in it's own right, perhaps triggered by the main event?

Boy, Galileo really started something with that little telescope thingy.
