    Earth Mars
AI Thread Summary
The image of Earth taken from Mars does not appear as blue as expected, leading to speculation about color perception differences between the two planets. Observers note that while the Moon is visible from Mars, it appears much fainter and may not be captured in short exposure photographs like the one taken by the Spirit rover. One participant suggests that a faint streak, possibly the Moon, can be seen in the image near Earth. The discussion highlights the limitations of photographic technology in capturing distant celestial objects. Overall, the conversation reflects curiosity about color perception and visibility of celestial bodies from Mars.

I thought it would look more blueish since we see Mars as red.

I wonder if it might look bluer to the naked eye. When I wear red-tint sunglasses, my eyes adjust and I can distinguish blues and other colors. But a photograph taken through my red sunglasses always keeps its red tint.

I hope I get to find out some day :)
 
I would have hoped you could see the Moon too - perhaps it is in alignment with Earth - Mars?

You could see the Moon from Mars with the naked eye; however, it would be several times fainter, and would not show up in the short exposure that Spirit took.

That makes sense. And upon further review I think I can see the Moon in that picture. Look off to the 1 o'clock position for a much fainter streak that is parallel to the one made by Earth. The fact that no other stars are visible in the image implies that fainter objects are indeed squelched from the photo like you suggest.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
