back to article ESO's nine-gigapixel galactic image has 84 MILLION stars

The European Southern Observatory has captured and catalogued a giant image of the centre of our galaxy that, if printed at “normal resolution”, would measure 9 x 7 meters. The nine-gigapixel image from the VISTA telescope at Paranal Observatory – this is just a Web version – has been catalogued by an international team of …

Isn't 108,200 x 81,500 the standard broadcast resolution in Japan?

Yeah, but it's largely pointless on the minituarised screens embedded in their watches

"pointless on the minituarised screens embedded in their watches"

Just means there is a good after-sale market for microscopes

So....

Does anyone still think we're alone? How egocentric would that be.

Re: So....

I never did think we were alone. There's simply too many galaxies, with too many stars, with too many planets to assume that ours is only one with the right ingredients to create and sustain life.

We can only hope that first contact is more in line with the Vulcans rather than the Borg.

Asked in jest

What's the file size of the complete image if it is recorded in "true color" using the BigTIFF file format? When will the entire image be made available online for download?

Re: Asked in jest

Astronomers use FITS = Flexible Image Tape System. It typically uses 80 byte records called "card images". That alone shows its age.

We are just adapting our code to handle FITS. I would love to put our parallel code through its paces on this image (biggest we have done so far is 3.9 Gpixel).

The entire image *is* available for download:

http://www.eso.org/public/images/eso1242a/

24.6GB, since you can't be bothered to look for yourself.

You'll need an astronomical amout of RAM to open it.

Great stuff

Now all we need is a Star ship (generation/city in space or warp), or star gate or similar.

It would have been an even clearer picture....

And they looked upon the universe spread before them

Re: And they looked upon the universe spread before them

Blow up the picture to a couple of metres height, and bend it so that the walls make a cylinder. The radius would be measured in metres as well. Then sit in the middle.

It's a DIY Total Perspective Vortex.

Interesting name...

So, South = Paranal? North must then be Paracranial?

Wouldn't inhabitants of the South Hemisphere be slightly put off by such classification?

It's not just a big distance to cross... there's a lot of history

When you consider how long life on earth has been around compared to galactic/universe time scales (difficult to find enough noughts), what are the odds that two occurances of "life" (however you wish to define it) would overlap in time, let alone space?

Yep, I think we are likely alone for our tiny point in space time

Re: It's not just a big distance to cross... there's a lot of history

Pretty high - life started on Earth (and effectively the universe) pretty much as soon as was practically possible. Very broad stroke, but in terms of the universe forming and going through the various stages of element creation through the various stars up to Population I stars (like ours) and a surrounding solar system, the formation of the earth, life started pretty much (in astronomical terms) as soon as the conditions were right.

If we assume the rest of the Population I stars underwent a similar cycle (and no reason to doubt they didn't) makes it extremely likely that life would start on similar timescales across the universe.

In short, for a lot of history across the universe, life wasn't possible. And even without that, we know that life on Earth has existed for about 1/6 of the universe's life.

I always thought that it was a bit of an anomaly with nature. In the context of the Sun and the Earth, the universe is really quite large. However, it the same context, its not really that old at all.

Wall mosaic

If you were to print that out onto a sheet of A0 paper (1189x841mm), you'd achieve 2318 dpi (90 dpmm )

Does anyone have a 1000 dpi A0 colour printer who could print it onto 4 non-overlapping sheet please?

"the survey has revealed a large number of faint red dwarf stars"

My guess is they mistakenly pointed the VISTA telescope at the Dave channel.

Stunning to know your place in the universe and how much of a nothing you really are in the grand scheme of things, maybe there's some way I can wangle that into the next pointless service call I get to reset the password of some dingbat who can't even remember a string of 9 characters for more than 5 minutes!

Re: so many millions of stars and planets...

My thoughts too. All those stars are merely one galaxy. Some of these images we've seen contain clusters of galaxies. My puny human mind cannot comprehend how vast the universe is.
