    Orbital Planes
AI Thread Summary
The Earth's orbital plane, known as the ecliptic, intersects with the Moon's orbital plane at an angle of approximately 5 degrees. These planes are not parallel or perpendicular; instead, they have a specific inclination. The orientation of the Moon's orbit rotates completely every 18+ years, while the argument of perigee completes a revolution every ~9 years. This dynamic interaction affects the intersection angle over time. Understanding these orbital relationships is crucial for studying lunar phases and eclipses.

Consider the Earth's orbit around the sun to be in a plane A and the moon's orbit around the Earth to be in a plane B. How do these planes intersect? Are they parallel or perpendicular? At what angle do they intersect themselves? Does the angle stay the same, or does it vary.

The Moon's orbit is inclined roughly 5 degrees to the ecliptic. The ecliptic is defined to be the plane of the Earth's orbit. The orientation rotates one complete revolution every 18+ years. The argument of perigee rotates one complete revolution every ~9 years. Click the link for an animation. This is viewed from the ecliptic, so if it were shown, the Earth's orbital plane would be a horizontal line through the center of the Earth.

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

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. In case of failure to detect...

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...
