Telescopes solve 2,000-year-old stellar mystery

CAPE CANAVERAL, Fla. (AP) — Astronomers finally know why the first documented supernova was super-sized.

The exploded star was observed by the ancient Chinese in the year 185, and visible for eight months. It was later found to be a bigger-than-expected supernova remnant, 8,000 light years away. Each light year is about 6 trillion miles.

New observations in the infrared show the explosion took place in a cavity in space. The cavity allowed the stellar shrapnel to shoot faster and farther out into the universe.

The star — similar to our sun — died peacefully and turned into a dense white dwarf. It sucked up material from another star, and then exploded in a supernova.

I would bet that half the people in the country think light year is a measure of time.

The other half think light year is a cartoon character.

No other unit of measurement gets this special treatment.

I've seen/heard a nanosecond quantified in distance.

What were the modern Chinese doing while the ancient Chinese were star gazing?

Buying American Congresscritters, of course!

Gee...I thought a cavity was kind of like space. Please enlighten me.

I saw that and loved it. It was an episode of a new version of Twilight Zone that didn’t catch on.

The next Decan in this group is Centaurus, a half-horse, half-man. This could represent the child who is born, having two natures: being both God and man. The last Constellation in this Sign is Bootes, or Arcturus, who is the Great Shepherd and Harvester. Together these images seem to portray, as in the Bible, the virgin birth of a child who has two natures, and the role of that child when he is grown as The Great Shepherd, leading His flock.

Libra, the Scales, is a pair of balances, the universal symbol of trade or commerce. It depicts a purchase, or in this case, a redemption. It stands for the price to be paid. The three Decans of this sign are the Cross (or the Southern Cross), the Victim, and the Crown. The Cross would be the most obvious symbol possible for the death of Christ, by which the price for our sin was paid. He Himself was the victim, and, since the victim is killed by the Centaur, which also presumably stands for Christ (from the previous Sign), we see again the idea that Christ willingly offered His own life. He said it was not taken from Him, but that He laid it down Himself. Thus, He was responsible for His own death. The Crown would picture the victory gained through the sacrificial death.

All that remains of the oldest documented example of a supernova, called RCW 86, is seen in this image, a combination of data from four different space telescopes to create a multi-wavelength view, released by NASA October 24, 2011. – Reuters Photo

If you must shrink to the size of a white dwarf....BEHAVE YOURSELF!!

Need to send these white dwarfs to catholic school. Sister Mary Killakid would teach them some manners!
