Pillars of Creation Toppled By Stellar Blast

SEATTLE They helped open the public's eyes to the wonders of space when they were first photographed in 1995, but a new study suggests the famous Pillars of Creation in the Eagle Nebula might have already been toppled long ago, and that what the Hubble Space Telescope actually captured was their ghost image.
A new picture of the Eagle Nebula shot by NASA's Spitzer Space Telescope show the intact pillars next to a giant cloud of glowing dust scorched by the heat of a massive stellar explosion known as a supernova [image].
Astronomers think the supernova's shock wave knocked the pillars down about 6,000 years ago. But because light from that region of the sky takes 7,000 years to reach us, the majestic pillars will appear intact to observers on Earth for another 1,000 years or so.
The supernova blast is thought to have occurred between 6,000 and 9,000 years ago, so what astronomers see now is evidence of the blast just before its destructive shock wave reached the pillars.
Astronomers have long predicted that a supernova blast wave would destroy the famous pillars. One earlier study concluded that the pillars would be destroyed sometime within the next million years. About 20 stars in the region are ripe for exploding and it was only a matter of time before one exploded.
The new Spitzer image suggests one of the stellar time bombs has already detonate. Humans living 1,000 to 2,000 years ago might have noticed the supernova event that destroyed the pillars as an unusually bright star in the sky.
In an end befitting their name, however, astronomers think that gas and dust from the pillar's destruction will help give birth to a new generation of stars.
The study, led by Nicolas Flagey of The Institut d'Astrophysique Spatiale in France, was presented here today at the 209th meeting of the American Astronomical Society.

So... could it be said that at the Incarnation of Christ, the Pillars of Creation were rocked?

The shock wave travels much slower than the light from the same event. Notice when a bomb/fireworks/lightning goes off, the light from the event is seen before the shock wave/sound hits.So the shockwave is some kind of particle that travels more slowly than light? Is it just the matter from the exploding star.

" Is it just the matter from the exploding star."Yes. They can tell the star already exploded from the effects of the light that already hit it. It would have raised the temp. of the nebula. They're looking at the effects that had. Once the paritcles in the shock wave arrive, the nebulla will be blown apart.

Exactly....Isaiah 48:6

The Armed & Rangerous in the Department of the Inferior are feverishly at work preparing a request to Congress for an astronomical amount of money to deal with the newly discovered violation of the Endangered Stars Act (ESA).
And we thought ESA meant endangered species act. We are soooo very fortunate to have Ranger Randy & Rangerette Janette hard at work safeguarding interstellar treasures for posterity.

Here's my question. Can you technically have "shock" or "sound" waves in space, without a medium for the waves to travel through? I mean, we all know that in space no one can hear you scream.
To: ModelBreaker; spunkets
For that matter, if a pillar falls in space and there's no one to hear it, does it still scream?
To: Excuse_My_Bellicosity
To: Larry Lucido; RadioAstronomer
Sound waves? No. Not as we think of sound (compressed gasses at near room temperatures and pressures).
A "shock" wave (through the thin (near-vacuum) plasmas and near-vacuum "dust" clouds) is possible.

So, let me get this straight: If we are looking at something 10,000 light years away, we're actually seeing it as, you know, like, it was 10,000 years ago?
DUUUUDE...
Am I missing something in this article. All I can see is that they are stating the obvious.
