AI Thread Summary
The sun's corona is the outer atmosphere of the sun, typically visible during a solar eclipse or with specialized equipment like a coronagraph. A photograph taken of the sun on a cloudy day using red cellophane may not accurately capture the corona, as the bright appearance could be due to cloud interference and the plastic's effect. Capturing the corona requires specific conditions, usually during an eclipse, to avoid overwhelming brightness from the sun. The discussion highlights the challenges of photographing the corona without proper tools or conditions. Understanding these factors is essential for anyone interested in solar photography.

I took a picture of the sun on a cloudy day with 2 layers of red cellophane on a normal camera, and edited it on the computer. There is some bright stuff around the sun in the middle. Can this possibly be the corona? :eek:

Unlikely. It's probably the clouds and the plastic making it look that way. This is the Sun's corona:

Note that you typically need an eclipse to be able to image it. Either that or specialized equipment like a coronagraph.
 
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...
