PBH submitted a link to a really amazing composite image of the Milky Way released by NASA. They combined infrared, visible, and x-ray images taken by Spitzer, Hubble, and Chandra to create one beautiful image to commemorate the 400 years since 1609, when Galileo looked up.

Hubble Photographs Jupiter's New "Scar" 60 comments
BearRanger writes "Calibration of new systems in the Hubble Space Telescope (installed in May by Shuttle Atlantis astronauts) were interrupted to take pictures of the new 'scar' near the south pole of Jupiter. The scar is believed to have been caused by the impact of an asteroid or small comet with the gas giant, which we discussed last Sunday. Hubble's return to service will be delayed by this interruption, but NASA says that rare events such as this warrant the delay. This is only the second recorded impact of an object with Jupiter."

Hubble Releases First Post-Upgrade Images 129 comments
Hynee writes "As tweeted, NASA has released 10 new images, all from the new WFC3 instrument and others, including the Cosmic Origins Spectrograph. Images include NGC 6302, Carina Nebula, Stephan's Quintet, Markarian 817, Abell 370, and a few others. Great looking stuff, the WFC3 has twice the resolution of the WF/PC2, on the CCD at least, if memory serves correctly. Eta Carina is a fascinating object, and there are at least two releases in this 'Early Release Observations' set."
Here is a video about the new images at Hubblesite.org, and a full HubbleSite.org release page with 56 images.

The sun is being occulted, the reflection of the rings are seen on the dark side of Saturn. Not to mention the little faint blue dot just below the thickest part of the outer bulry ring, on the left side is supposedly Earth.

The Keck I telescope quietly pouts. "We're pretty great," it says. "We're a great observatory."
"I know, I know," says the Keck II consolingly. "It's just a name; don't let it get you down. We'd beat them in a second if we weren't too big to put in orbit."
"Are you saying I'm fat?" Keck I cries.
"Come on, that's a good thing for a telescope, am I right?" the Keck says encouragingly. "We're the fattest!"
"Yeah!" Keck I says brightly, spirits seemingly lifted. But as Keck II returns to observations, Keck I still feels the sting of not being in the spotlight.
Later, scientists analyzing data from Keck I find minor anomalies, caused by unexplained water droplets on the primary.

does anyone know where can I download huge versions of these kind of images? I always wanted to make a poster, I thought of getting a big enough one to make it 300 or 600 dpi at a large size (at least 1 meter width), and have it printed.

There's an annotated image here [hubblesite.org], which inexplicably has a scale in light years/parsecs. I mean, it must be talking about at a particular depth, maybe the dust cloud the Hubble imaged? The arc-minutes/seconds scale, at least, makes perfect sense.

Nah, no I don't. If we take the length of the triangle as 30,000 and the angle as 2 * 0.25 degrees ( to split it into two right triangles), then sin(0.25 deg) * 30,000 = 130.9 light years, times two, gives about a 262 light year wide image, which means each pixel at 1920x1200 covers a square of about 0.136 light years (1,286,631,860,000 kilometers) per side.
For comparison, that's about 8600 AU (Earth-Sun distance). The solar system to the Heliosheath (where the Voyager probes are) is about 100 AU. So each pixel is a square, 86 solar systems across.
Now that's a big pixel...

The entire picture appears about 45 arcminutes across. So if the full Moon drifted in front of this picture, it would cover all but the outer edges.

Galileo was born in 1564 [wikipedia.org]. I'm pretty sure that in 45 years he had at least one chance to look up...
Anyway, pretty picture. Now, in a few years when pollution and terrestrial lights has hidden the details of the night sky even in the remote, uninhabited regions, our grandchildren will say:
Grandad, did the sky really look so beautiful back then?
And we will bring out a wide, warm smile and say:
Not even remotely!

It's amazing how something so obvious in retrospect was such an intuitive leap forward in (ahem) the dark.
Telescopes existed for some time before Galileo, but in extremely limited quantities and mainly used for practical purposes, such as scanning for mast and sails of ships as they emerged in the horizon.
In those days, the church told you how the heavens went, and that was that. After plenty of leeway for intellectuals during the Middle Ages, a panicky Vatican was in full-tilt political damage control mod
