    Circle Moon
AI Thread Summary
The lunar poles do have a region similar to an Arctic circle where the Sun and Earth can be visible for extended periods. The Moon's axial tilt is approximately 1.5 degrees, which affects the visibility of celestial bodies. This results in a limited area, approximately 45.5 kilometers (28.4 miles) from the pole, where this phenomenon occurs. The unique geometry of the Moon's tilt creates distinct visibility patterns at the poles. Understanding these dynamics is essential for lunar exploration and potential habitation.

Do the lunar poles have something like and Artic circle where the Sun and/or Earth are fully visible in the sky for very long periods of time?
 
Astronomy news on Phys.org
Yes, but the Moon's axial tilt with respect to the Sun is only ~1.5 degrees. This means the equivalent of an Arctic circle would only be about 45 1/2 km (28.4 miles) from the pole.
 

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.

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...
