AI Thread Summary
Capturing photographs of the Milky Way from Earth is limited to viewing a broad band of stars, gas, and dust due to our position within the galaxy. A complete view of the Milky Way's spiral structure is impossible without being outside of it, similar to how one cannot photograph Earth from its surface. Any artistic or computer-generated images depicting the Milky Way as a spiral are not accurate representations. True photographs would require a satellite to venture tens of thousands of light years away, a process that would take millions of years. Currently, no satellites are on such a mission, making authentic images of the Milky Way from outside unattainable for the foreseeable future.

How it is possible to capture photographs of milky way. I mean just take a case that we can't take photos of Earth while being on it. For it we have to go out of earth.

Same way it's possible to take photos of new york from the brooklyn bridge - we are near the edge of the galaxy, if you look toward the core you see the majority of the stars in it.
 
it is true that the Milky Way cannot be viewed in its entirety (spiral configuration and all) without being completely outside of it. this is the reason that every photograph of the Milky Way you've ever seen looks like a broad band of stars, gas, and dust running across the sky, with no discernible spiral configuration from within. if you've seen a photo of the Milky Way depicted as a beautiful spiral entity, rest assured it was an artist's or computer's rendering, and not the real thing...

...in other words, the only way to depict the Milky Way in its entirety is to make a false rendering, or perhaps wait several million years for one of our artificial satellites to venture far enough from the plane of the Milky Way to take a true picture. in this case, the satellite would have to be tens of thousands of light years above or below the plane of the galaxy. and once the picture is taken, it would take tens of thousands of years to transmit the picture back to Earth for viewing. so at the very earliest, we wouldn't see a true photograph of the Milky Way taken from outside of it for at least another several million years. at current, i know of no satellites on such a mission.
 
Ok. I got my answer. Thanks to both
 
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. In case of failure to detect...
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...
This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
