I sometimes let my imagine run wild! :lol2:
Like a small mouse! :wink:
The mouse that ROARED?

The "FireFox" nebula? The "Little Mouse" nebula? Come, your imaginations are running wild.

I dub thee "Seagull Poo" Nebula!

I'm guessing the star is near the RH of the firefox. If is is then are we just seeing X-rays from the bubble that it approaching us and if so does that mean the X-rays tend to be sent in the direction of the expanding gas cloud?
The brightness of the X-rays from the sides of bubble would suggest not.

:arrow: The gases are millions of degrees hot such that heavy metals like iron radiate thermal X-rays equally in all directions.

I was surprised... which IS easy to do... that at only 2000-5000 years old...it is 25 light years in diameter. But considering the Crab Nebula is only 965 years old...at 11 light years in diameter, I guess it makes some sense...I just thought it would have been smaller for some reason...

The Firefox looks like he is in distress... no doubt... big explosion... lots of Shock...

Image N63A: Supernova Remnant in Visible and X-ray

Explanation: What has this supernova left behind? As little as 2,000 years ago, light from a massive stellar explosion in the Large Magellanic Cloud (LMC) first reached planet Earth. The LMC is a close galactic neighbor of our Milky Way Galaxy and the rampaging explosion front is now seen moving out - destroying or displacing ambient gas clouds while leaving behind relatively dense knots of gas and dust. What remains is one of the largest supernova remnants in the LMC: N63A. Many of the surviving dense knots have been themselves compressed and may further contract to form new stars. Some of the resulting stars may then explode in a supernova, continuing the cycle. Featured here is a combined image of N63A in the X-ray from the Chandra Space Telescope and in visible light by Hubble. The prominent knot of gas and dust on the upper right -- informally dubbed the Firefox -- is very bright in visible light, while the larger supernova remnant shines most brightly in X-rays. N63A spans over 25 light years and lies about 150,000 light years away toward the southern constellation of Dorado.
