Makes ya think, just a little. Go see the original pic at Subnormality and for the rest of the yummy archive.
A pox on dust, and a severe reprimand for both (well not really) that are messing with our ability to observe the universe around us.
“Cosmic dust is fogging up attempts to study light left over from the Big Bang, and Canadian scientists aim to clear up the problem. The microscopic dust permeates the universe, producing confusing signals in data collected by the Planck space telescope, which is designed to study distant light originating from the beginning of the universe 13 billion years ago. The dust — mainly sand and soot particles, each about the size of a bacterium — makes up about one per cent of the mass in space, not very much compared with the mass of hydrogen and helium, said University of Toronto astronomer Peter Martin.”
Not exactly a problem a good spring cleaning is going to fix.
“Our cosmologist friends would call it ‘noise’,” Martin said. “It’s not blocking [the radiation]. It’s adding to the signal and therefore confusing what might otherwise be pure cosmological cosmic microwave background radiation.” Martin and his colleagues are trying to figure out what microwave signal the dust produces as it glows so that signal can be subtracted out of the overall data, leaving behind the pure microwave background radiation.”
Hopefully the right algorithm can be concocted to compensate for the dust that is making the data in question hard to interpret. One of the neat side discoveries about the dust itself does provide and interesting tangent.
“In the meantime, they have made some interesting discoveries about the dust itself. Based on the signals they measured, for example, they’ve found that some of the dust particles are spinning billions of times a second.
That was one of the first scientific results gathered using the telescope, which was launched in May 2009. It will continue collecting data until the end of 2011 from an orbit 1.5 million kilometres from Earth, toward Mars.
Martin thinks the dust is fascinating in itself because it is where heavy molecules generated within stars, such as carbon — including the carbon that makes up our bodies — has spent most of its existence over the past five billion years.
“When you’re talking to your friends, you’re talking to people that in an earlier existence used to be this interstellar dust.”
The idea that we are stardust and were outgassed from a star a couple billion years ago is pretty cool. Isn’t science grand?
Liberal Viewer does a masterful job of bringing to light the waste involved in killing our fellow human beings.
It is really quite silly. The U.A.E wanted more airplane births here in Canada. Canada said no. The U.A.E has responded with a series of measure that makes entering and doing business in the U.A.E, for Canadians, much more inconvenient. The latest hiccup has been with two Canadian business people:
“Darius Mosun and his business partner, Jonathan Mark, spent more than 15 hours stranded at the Abu Dhabi airport because of confusion over new visa rules imposed on Canadian travellers. Although their visa allowed them to enter the U.A.E. last week, they were blocked from entering that country a second time on Friday after making a side trip to Saudi Arabia. They were told their visas were only valid for a single entry, even though that rule wasn’t written on the document itself.”
I’m not really sure why Harper and his merry men have denied the U.A.E more landing births in Canada, but the result is that Canadians travelling to the U.A.E they are facing trial by red-tape as soon as enter the airport.
“Mosun also said he noticed that Canadians were singled out at the airport for additional screening, something he hadn’t experienced on previous trips. After arriving in Toronto, Mosun, 42, said such “major inconveniences” make it tough for Canadian companies to compete in foreign markets. He said he’ll be contacting officials in Ottawa to urge them to protect Canadians travelling for business who may be affected by the diplomatic spat. The new rules were imposed at the start of the month after Canada refused last fall to grant the U.A.E.’s two major airlines increased landing rights.”
The whole situation just seems a bit childish to be perfectly honest. It is not like we are the US or anything and simply threaten and bully the U.A.E to acquiesce to our demands/rules. We must come to a settlement that benefits both parties, a compromise that benefits both parties poorly. It is the Canadian way after all. :)
