Comment Hubble should be scientifically correct.... (Score 0) 114

If I want artistic freedom, I can watch video games or movies (where lots of hubble images end up anyway). So the more scientifically correct you can get, the better. Using non natural colors is OK, but even then it would be good if every movie / image would identify which colors are original and what is artistic freedom. I suspect a large number of people believe that many artistically colored images show normal spectrum images. -Bernd

Amazingly accurate for someone so plastered. I think all history should be taught at this level of intoxication.

Space Exploration Needs Extraterrestrial Ethics 162

An anonymous reader writes "Professor Andy Miah notes there's already international government policies taking hold on outer space — and a need for new ethical guidelines. 'For instance, what obligations do we owe to the various life forms we send there, or those we might discover? Can we develop a more considerate approach to colonizing outer space than we were able to achieve for various sectors of Earth?' And what rights do astronauts have? 'Could our inevitable public surveillance of their behavior become too much of an infringement on their personal privacy?' But more importantly, professor Miah notes that 'the goods of space exploration far exceed the symbolic value,' pointing out that 'A vast amount of research and development derives from space exploration ... For example, the United Kingdom's 2007 Space Policy inquiry indicated that the creation of space products contributes two to three times their value in GDP.'"

Comment ghosts identified (Score 1) 3

News from the twilight zone... the ghosts are inside the bed sheets ;-) I have to correct myself here. After some more experiments I did indeed found a way to wake up the GHOSTS... And that is indeed by just shaking the blanket and then quickly making lots of images with a flashlight. Surprisingly it sometimes leads to exactly the same pattern. Thanks for the hint!

Comment Re:Probably dust (Score 1) 3

I would agree if it would only be the white ball, but it seems to have a circular very fine structure in its center. Also, a dust particle would have to be very close to the lens (less than a cm I would say) to be this big. How could an object that close be in focus enough to show such a clear shape and be lit by the flashlight (which is embedded in the case of the camera and about 2 cm away from the lens: http://images.pcworld.com/news/graphics/189780-sonytx7_slide.jpg Dont get me wrong. I sure don`t want to insist on a paranormal explanation here, but also don`t think the scientific explanation can be that simple. The image sensor is a backlit CMOS btw. http://www.alphamountworld.com/photography-news/sonys-back-illuminated-cmos-sensor I wonder if something rarely goes wrong at the surface level of the sensor (high energy particle impact?) could it create such large (many hundred pixel) effect? -Bernd

Submission + - Ghost orb or cybershot TX7 firmware bug? 3

zav42 writes: I need people with some common sense to help me disproof "ghost orbs" on a picture I have just taken with my newly aquired Sony Cybershot TX7 camera.
Googling this phenomenon only brings up lots of lunatics websites, but I want people of SCIENCE to help me out. So is /. the right place?

I was sitting in bed experimenting with my new DSC TX7 and this one image taken with a flashlight shows a very clear orb image. I am well aware of lens flares, and yes there is a very bright spot on this image (the reflection of the flash light on the TV screen), but the orb is way too structured and in the wrong place IMO. I could not repeat this result even after many attempts from the same location and with the same camera settings.

Since I don`t believe in ghosts, my favorite theory so far is that this is a firmware bug or a side effect of the "demo mode" that was active in the settings of the camera (Demo mode 1 for those who have the camera). You have to know that this camera has a number of quite advanced features. It can for example recognize faces to control the shutter the moment a person smiles. (To avoid sounding like a sony viral marketing person, I have to also point out that the UI of the touchscreen is awful.)

So if you feel fit to judge paranormal activities OR detect a firmware bug OR explain a very unusual lensflare, then please have a look at this image:

Obligatory oath: I swear I did not alter this image in any way. It comes right from the memory stick of the camera.

Submission + - Did scientists reduce lifespan of universe?

zav42 writes: "Observing a supernova in 1998 might have lead to a significantly reduced lifespan of our universe.

This conclusion of two scientists from Case Western Reserve University in Cleveland soon to be published in an article in new scientist sparks some controversy among their colleagues.
Can the Quantum-Zeno effect be applied on such a scale?
MIT`s Max Tegmark answered this by remarking that the effect does not require human observers. The galaxy was watching all the time.

A more indepth German version was just just published at Spiegel Online."
