The five supernovae are all within 350 light-years of one another in the merging galaxy, called Arp 229. Two of them are just 7 light-years apart.

I think I'd rather have Halton Arp's take on the observation.

Supernova factory? Are we now expoting jobs to other galaxies, as well?

Go here for many pictures from Arp's Atlas of Peculiar Galaxies. This is a site maintained by someone who has decided to have a look at each of the galaxies in the atlas. Arp 199 is pretty cool looking. I tried getting this book from the Yerkes Observatory library, but someone had stolen it.

Great name for a band.

.... the Very Long Baseline Array, which combines the efforts of 10 antennas spread from Hawaii to the Virgin Islands to gain greater sensitivity. [emphasis added]

This is somewhat misleading; the fact that the 10 antennae are spread out from the Virgin Islands to Hawaii contributes nothing to the sensitivity of the array; the same 10 antennae parked next to each other would have the same sensitivity. What spreading them out does (which is why it is called the Very Long Baseline Array) is it increases the effective resolution of the array, far greater than can be obtained by a single dish of equivalent apeture.

This means the VLBA can resolve more detail than a single dish of equivalent apeture, but cannnot detect signals that are any weaker than what the equivalent single dish would detect.

How many special people change
How many lives are living strange
Where were you while we were getting high ?

Slowly walking down the hall
Faster than a cannonball
Where were you while we were getting high ?

Some day you will find me
Caught beneath the landslide
In a champagne supernova in the sky
Some day you will find me
Caught beneath the landslide
In a champagne supernova

A champagne supernova in the sky

Wake up the dawn and ask her why
A dreamer dreams she never dies
Wipe that tear away now from your eye

Slowly walking down the hall
Faster than a cannonball
Where were you while we were getting high?

Some day you will find me
Caught beneath the landslide
In a champagne supernova in the sky
Some day you will find me
Caught beneath the landslide
In a champagne supernova

A champagne supernova
Cos people believe that they're
Gonna get away for the summer

But you and I we live and die
The world's still spinning round
We don't know why why why why why


How many special people change
How many lives are living strange
Where were you while we were getting high?
We were getting high
We were getting high
We were getting high...

"This supernova is likely to be part of a group of super star clusters that produce an average of one such stellar explosion every two years," said James Ulvestad of the National Radio Astronomy Observatory.

How do they figure this out?
