    Moons Planets
AI Thread Summary
Not all planets have moons; specifically, Mercury and Venus do not possess any. Moons can form through various processes, including the capture of asteroids, debris from planetary collisions, or co-formation from the same dust disk as their parent planet. The origin of Earth's moon is likely due to a massive impact that ejected material into orbit. Understanding these formation processes provides insight into the dynamics of planetary systems. Overall, the presence of moons varies significantly among planets in our solar system.

Being new to astronomy, I was wondering, do all planets have moons? What are they? how did they get there?

No, not all planets have moons - Mercury and Venus don't.

Moons are generally either captured asteroids, blasted off pieces of the planet they orbit (our moon, probably), or just formed from the same disk of dust that formed the planet they orbit.
 

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...

Thread 'Our Beautiful Universe - Photos and Videos'

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. I start this...
