What gas giant, what moon(s) are split in half and.

AI Thread Summary
The discussion centers around identifying a gas giant with a moon that is split in half, where the two halves exchange positions. The moon in question is likely Iapetus, which orbits Saturn and is known for its distinctive two-tone coloration and unique shape. Participants reference co-orbital moons and provide links to relevant Wikipedia articles for further information. The inquiry emphasizes the need for clarity regarding the specific gas giant and the names of the two halves of the moon. Ultimately, Iapetus is highlighted as a significant example in this context.

Hello,

I searched and searched, even emailed my astronomer friend in the land down under but I need the answer NOW! LOL.

One of our gas giants has a moon that is split in half and when the two halfs meet they trade places.

Which gas giant?

What are the names of the two half moons?

Thanks!
Rusty

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?'

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...
