The discussion revolves around the latest high-definition images released from the Hubble Space Telescope, focusing on their aesthetic appeal, technical quality, and the implications of digital processing in astronomical imaging. Participants share their excitement and experiences with the images, while also addressing concerns about image quality for personal use.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants express joy over the new images from Hubble, highlighting their beauty and the advancements made after recent upgrades.
  • Others question the authenticity of the images, jokingly suggesting that they must be digitally altered to appear so stunning.
  • There are discussions about the use of digital technology in enhancing images, with some participants noting that they have seen similar images through non-enhanced telescopes.
  • Concerns are raised regarding the quality of the images for use as desktop wallpapers, with multiple participants reporting issues with graininess and pixel noise.
  • Some participants note that the images may not undergo the same level of processing as amateur images, which could affect their visual quality.

New Images just released from Nasa-
So happy we still have Hubble!

They're everywhere on online, though
You can find them on Youtube, at "Hubble Spectacular First Light Images in HD".


cheers,

Souped-Up Hubble Makes A Comeback

New images from the recently refurbished Hubble Space Telescope show that the 19-year-old observatory is now more powerful than ever.

Ever since astronauts traveled to the orbiting observatory in May and did a variety of upgrades, scientists have been testing and calibrating the telescope. At a press conference at NASA headquarters in Washington, D.C., officials released some images to demonstrate that the new and improved Hubble is working as planned.

The pictures show awe-inspiring cosmic scenes such as a "butterfly" nebula around a dying star, the stunningly colorful core of a giant star cluster, a quintet of galaxies, and a so-called pillar of creation where stars are being born.

Looking forward to more great images! :cool:

All images I've ever seen from the Hubble have left me in awe. Which is why I have concluded they were all made in photoshop (nothing that beautiful can exist in real life).




:D joking. These are really some more GREAT pictures to add to the Hubble collection. Just keeps gettin better 'nd better.
 
I too am in awe of the images of the universe as seen through the 'eye' of Hubble Space Telescope. Of course digital technology could be used to generate such pictures, and in the past we've seen digitally or colour enhanced images. But I've seen similar pictures through a reflector telescope without enhancement - so I know they are more or less real.
 
Too bad they are not good for desktop wallpaper - tried a few, turned out grainy. Photoshop definitely needs to play on those.

Which image did you download? I downloaded the large version of the lensing cluster Abell~370 and it looks pretty good as a wallpaper.
 
Tried a few in the wallpaper section. All have multicolored pixel noise, especially the nebulaes. My monitor is 1680x1050 pixels and I can clearly see non-uniform colors and colored noise in the darker areas, it's either they didn't process the pics well or it's just limitation of the telescope itself.
 
I see some on the first one, but it looks like a crop and blow-up of the HUDF. The crab neubla looks good to me.

Generally, though, they don't apply all the processing amateurs do - smoothing the image would decrease the real data and decrease the scientific value.

Here is a link to the Abell 370 very large image:

I'm not sure if you downloaded these large versions, but they are available for the other images, too.
