Hmmmm... that's pretty cool if it works out in practice. I see the article says there's a patent pending so it's not surprising they're being a bit stingy on details.

It's almost guaranteed that a new method of extraction will have different errors and give different results, so a lot of old dates established by old methods will probably end up being retested (assuming samples still even exit). If it's half as good as the article implies, it'll be revolutionary.

{{Something big and bright has gone boom 200 million light years away!

A massive explosion spotted 200 million light years from Earth has baffled astronomers.
The strange spot, nicknamed 'the cow', is up to 100 times brighter than a supernova and is growing at an incredible rate.
Scientists say the flash is a 9,000°C (16,000°F) cloud of high-energy particles bursting outwards at 12,000 miles (20,000km) per second, but are still unsure what triggered the brilliant blast.
One researcher said 'there hasn't really been another object like this.'
The explosion was captured on by the asteroid-tracking ATLAS telescopes at the Keck Observatory, which sits atop Mauna Kea, a dormant volcano in Hawaii.
Astronomers noted the flash was unusually luminous - between 10 and 100 times brighter than the average supernova - but it was the speed of its appearance that really caught the eye of space experts.
Most celestial explosions take weeks to reach peak brightness, but the distant flash had grown to a dramatic size in just two days.
Teams from around the world trained at least 18 telescopes on the flash in a response that constituted the largest number of reports for any single object on Astronomer's Telegram, according to the site's Editor-in-Chief.
The explosion was so bright it initially appeared to originate from our own galaxy, but observations by a group of Chinese scientists showed the spot was almost 200 million light years away.
Readings from other groups suggested the flash was an explosion of high-energy particles travelling outwards at 12,000 miles (20,000km) per second.
The surface temperature of this cloud could be as high as 9,000°C (16,000°F), according to the observations.
'We're not sure yet what it is, but the normal powering mechanism for a supernova is radioactive decay of nickel, and this event is too bright and too fast for that,' Dr Maguire said.
Follow-up observations are ongoing and scientists said they should know more about the object over the next day or two.- Daily Mail


Need to keep an eye on this see what they reckon it is. }}}

That's quite interesting! Have to keep my eye out for more news.

Cool, but I don't think I'd want one in my immediate celestial neighborhood..... affraid

If you find more details, could you please share them?
