Rather than copy an individual image to this discussion thread, the above link will feature a different picture every day.

Image of the Day is a good place to feature this page of the official NASA site. It's amazing what we can see from the Cellar ... with the power of the Internet and the budget of NASA.

Our discussion thread will not always refer to the same picture.

The images are always out of this world.

...just kidding.
But Tony has featured a few pix from there in the past, as well as the Earth Sci pic of the day. One of my favorite IotD's <b>(aside from this one)</b> is Nat'l Geographic. Today they have a photo from Hawaii that is just spectacular. Check it out. I also frequent photo.net, though they feature just a pic of the week and a random one every time you hit reload. There's some wonderful talent there.

The way I see it ... the Cellar is about community, not content.

The images here aren't unique content ... the discussion is.

Discuss.

I'll still post images to IotD from there, no matter how often it's referenced. A lot of people will just browse here, not checking out other regular image haunts. (I check them all. I have a lotta free time.)

Perfect. It would be great if anyone continues to use this link as a source, and wants to post any particular image for discussion.

The images on this link are there only for the day, unless you search their archives.

If any particular photo prompts discussion ... let's get at it.

Post and discuss.

Talk about high-res ... one of these images is a TIFF file of 71.9MB.

World's Most Complex Radio Telescope Snaps Stunning 1st Photo of the Cosmos
Fox News Published October 03, 2011 | Space.com

After years of planning, construction and assembly, a gigantic observatory
billed as the world's most complex array of ground-based telescopes
has opened its eyes in South America and captured its first image.
<snip>
ALMA is a complex of 40-foot (12-meter) radio telescopes sitting at an elevation of 16,500 feet (5,000 m)
on the Chajnantor plateau in northern Chile.
<snip>
Currently, the array harbors 19 individual telescopes, though 66 should come online by 2013,
researchers said. The array will ultimately be about 11 miles (18 km) wide.

My first question: Can anyone live/work at this altitude without oxygen ?

I saw it back in 2004. I used sunglasses, while looking at the sun through a compact disc. At dawn.

It was preeeety kewl.

technically, those water droplets *are* reflecting light from the Sun, it's just a bank shot from the Moon.

otherwise, that is a stunningly beautiful picture.

Explanation: Why would the shadow of a space shuttle launch plume point toward the Moon? In early 2001 during a launch of Atlantis, the Sun, Earth, Moon, and rocket were all properly aligned for this photogenic coincidence. First, for the space shuttle's plume to cast a long shadow, the time of day must be either near sunrise or sunset. Only then will the shadow be its longest and extend all the way to the horizon. Finally, during a Full Moon, the Sun and Moon are on opposite sides of the sky. Just after sunset, for example, the Sun is slightly below the horizon, and, in the other direction, the Moon is slightly above the horizon. Therefore, as Atlantis blasted off, just after sunset, its shadow projected away from the Sun toward the opposite horizon, where the Full Moon just happened to be[/CENTER]

Way beyond Mars: scientists release biggest 3D map of the sky
Talk about a giant data set: scientists at the Sloan Digital Sky Survey III (SDSS-III)
have released the biggest three-dimensional map of the universe ever created.

Using data collected by a 2.5-metre wide-angle optical telescope at the
Apache Point Observatory in New Mexico, scientists were able to
pinpoint the locations and distances of 1.35 million galaxies.
"We want to map the largest volume of the universe yet, and to use that map
to understand how the expansion of the universe is accelerating,"
said Daniel Eisenstein, director of SDSS-III, in a statement.>snip>

After a previous release of data from the Sloan Digital Sky Survey,
Aragon-Calvo created a short film (above)* that lets viewers fly
through a mostly accurate 3D model of the universe.
While the 400,000 galaxies you virtually swoop past in the film are in
the right spots based on the data available at the time, Aragon-Calvo
had to magnify the galaxies so that you can actually see them.

For anyone in biochemistry who has ever purified proteins or DNA,
this simulated flight among the galaxies is almost deja vu.

So you're a grave digger who dabbles in the occult?
BigV • Aug 24, 2012 2:03 pm
I prefer occulted graves, myself, regardless of who dug them.
