" To capture the large portion of the galaxy seen here — over 40 000 light-years across — Hubble took 411 images which have been assembled into a mosaic image."

" To capture the large portion of the galaxy seen here — over 40 000 light-years across — Hubble took 411 images which have been assembled into a mosaic image."
"The image featured here has 69 536 x 22 230 pixels and is a cropped version of the full uncropped image which has 3.9 billion pixels and covers a length of almost 60 000 light years."
Here is a link from the article that would help appreciate how detailed full resolutions is: http://www.spacetelescope.org/images/heic1502a/zoomable/ http://www.spacetelescope.org/images/heic1502a/zoomable/
I was blown away in particular by sheer luminescence difference between galactic core and edge of the galaxy. Imagine the brightness of night sky in galactic core. That reminded me of the paper that estimated number of GRB's that would hit a planet based on where it was located - galactic core is not a hospitable place.
- Springtime 12y agoAfter being stunned by the close-up of the stars I'm tempted to download the 4.3GB original [1]. The scale was unexpected having mostly seen only resized photos before.

- SSLy 12y agoWhat program can open such file?
- ChrisGranger 12y agoThat's a Photoshop Big file, which can be opened with Photoshop, obviously, provided your computer has sufficient RAM.
- SSLy 12y agoSo I guess it won't be of much use with my linux box...
- ChrisGranger 12y agoI've done some searching, but I haven't found any software that supports .PSB on Linux. Perhaps there's a plugin for The GIMP that would work, but I was unable to find one, sorry... It's probably more trouble than it's worth, but you could install Wine and Photoshop on your Linux box, or find someone with a Windows machine and Photoshop who could convert the file to another format that you're able to use, like .PNG for example.

- linguaz 12y agoIf the psb format can be converted to ppm format (via ImageMagick?), and image size is the issue, maybe NASA's BigView could be an option: BigView allows for interactive panning and zooming of images of arbitrary size on desktop PCs running linux. Additionally, it can work in a multi-screen environment where multiple PCs cooperate to view a single large image. Using this software, one can explore -- on relatively modest machines -- images such as the Mars Orbiter Camera mosaic [92160x33280 pixels]. http://ti.arc.nasa.gov/opensource/projects/bigview/ http://ti.arc.nasa.gov/opensource/projects/bigview/
- phkahler 12y agoFrom previous experiments, any program that stores image data in quad-tree order (or even just tiles, but I hate tiles) should be able to pan around such an image with little effort even if you have only a fraction of the RAM but plenty of swap space. Of course zooming out will require either the full RAM or MIP maps. But IDK a specific app.
- bsmith 12y agoIf anyone has succeeded in downloading the original from here or elsewhere...care to provide a mirror/torrent magnet link?
- jacquesm 12y agoAmazing how much large scale structure is visible in that image.
