Cool Space News

Scientists from around the world are building the world’s most advanced radio telescope in Chile’s Atacama Desert, on a plateau half-way between Earth and space above 40 percent of the planet’s atmosphere.

The observatory, referred to by the acronym ALMA, officially known as the Atacama Large Millimeter/Submillimeter Array, is the highest ever built. Located at 16,500 feet, the antennas will pick up radio and microwave signals from the edge of the universe to see things in space that were once invisible.
There's a good video there talking about it and showing it as well.


ps - I know Greedy is gonna be all over this [:D]  (enjoy it GT!!)

Robot football,cool Space stuff...

you are awesome




GreedyTop -> RE: Cool Space News (7/15/2012 8:43:36 AM)

I love you, MG!!




MercTech -> RE: Cool Space News (7/15/2012 8:50:48 AM)

I hate web pages that start with the automatic noise at full volume...




GreedyTop -> RE: Cool Space News (7/15/2012 8:52:21 AM)

I didn't get noise :( and I have my volume on, because I've been watching Netflix!!

I read about this...and they're spending a bundle of money on it....and those in the know say it's going to open up new frontiers....but I don't get how?

Isn't Hubble a smidge higher....with less light interference?

I know these scientists know what they're doing but...seems kinda odd...right?

I love you GT (even though you don't love me).




GreedyTop -> RE: Cool Space News (7/15/2012 5:25:54 PM)

aww... you're adorable, Lookie!!!




pyschosubmission -> RE: Cool Space News (7/15/2012 5:27:30 PM)

and there was me about to go on about the brutality of unrequited love...

was gonna be really sweet too

First Hubble is a visual telescope and these are RADIO telescopes. To answer why these will be so much better than anything before is because it's being built in a high altitude of the DRIEST desert on earth. This greatly reduces the amount of water vapor they have to see through, that might otherwise distort or diminish the incoming signals.

Okay...now I get it.

I don't care till America gets off its lazy ass and goes back to the moon or to mars




outlier -> RE: Cool Space News (7/16/2012 5:31:42 PM)

Thanks for this I enjoyed it.

Just to be a little more pedantic (because it's so unusual for an engineer to be pedantic):

Radio telescopes use separated antennae to allow for better detection of a vast spectrum of wavelengths of radiation. Calling them radio-telescopes isn't quite accurate, they are better called Very Large Arrays (VLA*.) While difficult to explain in the form of a text post, they basically use mathematics to imitate a very large lens. The Hubble telescope has a lens that had to fit in to a shuttle bay. It's only 7.9 feet wide (2.4 meters.) By contrast a VLA is often hundreds of meters in size. The one in question uses dishes that are 12 Meters (39.4 feet) in diameter. And there are 66 of them - about 3 miles higher than the heavy atmosphere at sea level - and there are going to be between 50 and 66 of them**.

So while the Hubble is higher, the Atacama Array is just so much fracking bigger that the elevation advantage is dwarfed.

Also, to divert from the rest of my post, this is freaking cool.

* Not to be confused with _the_ VLA in New Mexico.

** Reports vary. Politics and money are involved.

Edited to remove excessive quoting.
