150 Gigapixel Sky Image Contains 1 Billion Stars
The Bad Astronomer writes "Astronomers have used two big telescopes to create an infrared survey of the Milky Way that is the largest of its kind: the resulting image has an incredible 150,000 megapixels containing over a billion stars. Something that large is difficult to use, so they also made a pan-and-zoom version online which should keep you occupied for quite some time. These data will be used to better understand star formation in our Milky Way, and how far more distant galaxies and quasars behave."
The interactive image is powered by IIPImage which happens to be Free Software and is cool in its own right (right click the image to get help — it has a full set of keybindings for navigation).
It's full of stars!
Assuming 8 bits per pixel, a 150,000,000,000 pixel image would be 419GB.
Give me Classic Slashdot or give me death!
It would make such a great wallpaper for my 250ft monitor.
Why this is not in 3D yet?!?
Peanuts to that. I think it's a long way down the road to the chemist's.
Now if we could just get a 150,000 megapixel image of the daytime sky, we wouldn't have to go outside at all.
What I find most surprising is that they report over a billion stars with an image containing 150 billion pixels. That's a much higher density that I would have expected.
I guess that my intuition in such things isn't very good, which, not being an astronomer, isn't surprising.
There are likely as many galaxies in the observable universe as there are stars in this galaxy.
Why do some of the stars look like they've got holes in them?

Does anyone know why almost all stars (it can be seen easier in big ones) have a black dot in the middle?
Awesome images and a great app, but it could be improved by allowing users to mark interesting features. The data set is too big for researchers to visually scan it all.
oops. mod me off-topic. posting to remove error mod.
dumber people are doing harder things everyday
This remind me a older one, 'only' 5 Gpixel: http://skysurvey.org/ :)

Clearly those stars are not all out there. There's just a big shell around us with holes poked through!
(... that was a joke, by the way)
For large sets, this will be our guide even unto death, for the LORD will work for each type of data it is applied to...
A billion stars seems like a lot but general consensus is that the Milky Way alone has 300 +/- 100 billion stars. So at best this is like 0.5% of the galaxy. I just read about the Baryon Oscillation Spectroscopic Survey looking at 300,000 galaxies and planning on hitting 1,000,000 eventually. The number of stars out there is truly mind blowing for us puny humans. It's really impressive if you stop to think about it.

Where is the arrow pointing to a star that says "You are here"?
A billion? - I kept counting forty-two. Then again, since it's not the whole Universe, maybe it was a only a subset like, say, two? Seriously, though, very impressive. As Adams understated, "Space is Big". Yep...
Tell me again about your "personal relationship" with the being that created all of that?
Sorry but what does size of the universe have to do with that? You seem to have a lack of self esteem
Hey, our species created the being that "created" all of that. We should have esteem++.
Unless we're not delusional.

Why are there so many holes in the image?

I find your circular logic amusing. Is this what you tell yourself to sleep at night? Does it keep your conscience at bay? Have you ever wondered why you are wired with a conscience that seems to war against your base desires?
