Venus: Slowing Rotation Detected by Venera, Magellan, and Venus Express

AI Thread Summary
Venus is experiencing a gradual slowdown in its rotation, as observed by Venera, Magellan, and Venus Express over several years. The planet has a retrograde spin, resulting in a day on Venus lasting approximately 224.7 Earth days. Speculation exists that in the distant future, Venus may start to rotate in the opposite direction. This change could eventually lead to one side of Venus consistently facing the sun. The ongoing observations highlight the dynamic nature of Venus's rotation.

Measurements by Venera, Magellan and Venus Express over a period of years indicate that Venus is slowing its already leisurely rate of rotation.

Venus has unusual retrograde spin, and one day on Venus is equivalent to about 224.7 Earth days.

Perhaps in a million years, Venus will begin to spin in the normal direction?

Respectfully submitted,

My guess - it will reach a point where the same side is always facing the sun.

Thread 'Does it make sense to build new radio telescopes?'

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...
