Why RCW 86 distance, age different? Bethlehem*? (28 Sep 06)

that would make sense, since the Jesus myth is a mix of repackaged Buddhism and the Horus/Isis story carried over from egypt and it's about the same time period and in the direction of finding out from "the East" from China.

Hi,

The APOD description says that RCW 86 is 8200 light years away. How can something that far away be the supernova seen in 185 AD, about 2000 years ago?

Well, the fact that it's 8200 light years away simply means that what we see of RCW 86 is 8200 years out of date for what's occurring there 'now'. So, when the Chinese astronomers observed the supernova occuring in 185 AD, it had actually occurred in 8015 BC, but the light was only then reaching them.

What we're observing now is the supernova remnant left behind by the supernova event, now 1821 years old from our perspective.

Basically, everything we see of this object is on a time-delay of 8200 years.

Hello Pat

Welcome to the Asterisk.

Qev hit the nail on the head.

The text for the Sept 28, 06 picture "RCW 86: Historical Supernova Remnant" describes it as being observed 1821 years ago and being 8200 light years away.

thanks, that makes sense.

That would simply mean that the catastrophic event occured just over 10,000 years ago. 1821 years ago the light that has been traveling for 8200 years finally reached us. 8200 + 1821 = 10021 years ago that the star exploded.

Yes Qev is right. The star actually exploded approx 10,021 years ago.
