A question related to solar system

AI Thread Summary
The term "solar wave" likely refers to "solar shock wave," which occurs when the sun's solar wind, composed of charged particles, interacts with a planet's magnetic field. Pluto is no longer classified as a planet because its discovery led to the identification of the Kuiper Belt, revealing it as one of many similar objects, some larger than itself. The debate continues on how to define a planet, with options to either expand the list indefinitely or establish clear criteria. Understanding these concepts is crucial for grasping the dynamics of our solar system. The discussion highlights the evolving nature of astronomical classifications.

Never heard of it. Can you provide some source material?

Because we named Pluto a planet before we understood the makeup of our solar system. The discovery of the Kuiper Belt shows us that Pluto is merely one of many. And we have now discovered other objects in similar positions that are even larger than Pluto, and we expect to discover even more.

We have two choices: we can add to the list of planets indefinitely, or we can create some sort of logical cutoff point as to what is a planet and what is not.

Possibly you mean "solar shock wave"?
The sun emits charged particles (electrons, protons ) this is called "solar wind". When this wind hits a magnetic field of a planet, it creates a solar shock wave.
 

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.
