The discussion highlights that the visibility of constellations in the southwest sky varies based on geographic location and time of year. It emphasizes that the sky rotates every 24 hours, affecting which constellations are visible at any given moment. Observers in different parts of the world, such as Australia and Maine, will see different constellations when looking southwest. Additionally, the Earth's orbit around the Sun causes changes in visible constellations over time. Understanding these factors is crucial for accurately identifying constellations in the southwest sky.

what are the most recognized constellations located towards the southwest sky?
Also, not everyone sees the same exact sky - for someone in Australia, the sky looks a lot different to the southwest right now than it does for someone in Maine.
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?

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...
