Why do some photos have black squares cut out of them from hubble, like this: http://nssdc.gsfc.nasa.gov/image/astro/hst_antennae_9734a1.jpg

Does anyone know what the native resolution of Cassini's various cameras are? I'm looking for VERY high resolution (> 3 megapixel) versions of images like the one below, suitable for producing a good 5x7 or even 8x10 print. Anyone have any links to such high-res photos? - Warren

Well, other people are posting pictures of where they've been so I'll post two of Guam! http://img225.imageshack.us/img225/8930/10000421uh.jpg http://img292.imageshack.us/img292/1012/10000432uy.jpg The first image is looking to the left of my balcony, the second is looking straight out...

I took a Fathers day hike, thought I'd share the view. Marys Peak is about 20mi west of my home, I haven't been up there in many years, thought it was time for a revisit. these are just some shots along the way. First the requisite waterfalls...

I'll turn the Disneyland pics to Zz now! I spent the night at a place called Yamzi Ranch, it is a working cattle ranch. Using sound grazing methodology and with a lot of work they have also restored to nearly pristine condition a 20mi stretch of the Williamson river and wetland to create one...

By popular demand, here are the member photos only in alphabetical order. Continue to post pictures and comments in the member photo thread, and the pictures will be moved here. I want to say thank you to tribdog for getting this started. Hypnagogue has spent the last few days gathering all...

Are there any other geology/palaentology enthusiasts that like to do a spot of fossil collecting when they get a chance? Or maybe you don't like geology, but just think ammonites are cool? What were your best finds? Where are your favorite fossil hunting spots? Photos would be nice. I...

“I was gobsmacked when I printed off the photos,” said Mr Done :smile: That is a funny sentence. http://www.halifaxtoday.co.uk/ViewArticle2.aspx?SectionID=700&ArticleID=971894

all sorts of stuff worth looking through http://www.weather-photography.com/links.php#misc

From Space.com, lots of really great shots from a tremendously exciting year in science. For those who don't know, this is the second golden age of astronomy/cosmology. http://www.space.com/bestimg/bestimg.php

If photons are particles of light, then do things that emit light (for example, lightbulbs) create photons? If they do, is there an equation for it? It's just something that's really stumped me for a few years now.

To view some nice photos of Perimeter Institute's new building that were taken on its official opening day (Oct 2/2004) see: http://agar.ca/gallery/pi20041002 Perimeter Institute is located in Waterloo, Ontario, Canada. More specifically, the new facility is located in uptown Waterloo...

in some photos, mixed among the red white and blue stars, are green stars. Any idea what causes this?

Looking for advice? Willing to share your expertise with other PF members? Brave enough to share & discuss your own astrophotos? Then this is the thread for you. Enjoy! In all our cosmological discussions, let's not forget to actually go stargazing once in a while! :biggrin: Thanks...

This came from a closed thread from 2003, but in light of new data and the fact that Mr. Martin has been on the radio this week telling millions of people that this object photographed by Cassini is the mothership he told of. One would think it's important to re examine his claim.

ok I'm not so sure if this topic is exactly where its supposed to be...in the biology section! :redface: oh well but the topic of the pics I'm looking for is called: "the relationship of living things and their environment" ...lol does anyone know where i can find high quality/ high...

Someone show me the really vile prisoner abuse photos... I mean, a dead guy beat with a rock and rape. That's vile, that's torture.That is what I'm assuming all the fuss is being made about. However, I haven't seen any of those pictures, and I don't think they have even been shown to the...

I saw photos on T.V I hope pictures like this will spread around so that people will start thinking with their conscious instead of their greed. I also heard that the Americans administration is afraid of such pictures being spread around and anti-war resentiment might rise again. I'm fully...

Does anyone know where to find some high quality bubble chamber photos? Any information would be appreciated.

I'm pretty much okay with pair production but in the eqt we have that a photo gives an electron and a positron. If we do it the other way round we have an electron and a positron giving 2 photos in order to conserve momentum. Why do we not have 2 photos of energy for pair production ir order...

My main job is to photograph science and technology subjects. Most of my work in recent years has involved photographing northern lights and polarstratospehric clouds (seen over artcic areas and play a role in ozone depletion). I am attempting to broaden my scope and have come up with a...
