What Does the Observable Universe Look Like?

AI Thread Summary
The discussion highlights a picture representing the observable universe, emphasizing that while it visually captures a vast expanse, it primarily depicts objects within the Milky Way. The image does not encompass the entirety of the observable universe but includes a few distant objects that are nearly zero distance from the Milky Way. Participants express admiration for the image's quality, noting it effectively illustrates the concept of the observable universe. Questions arise regarding the picture's source and the method of its capture or generation. Overall, the conversation underscores the distinction between visual representation and the true scale of the universe.

Nice picture, it definitely is a picture of what in ordinary language might be called 'observable', with a half decent set of lenses.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
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.
