AI Thread Summary
The colorful rings observed around the moon are caused by the refraction of light through water droplets or ice crystals in the atmosphere. This phenomenon is similar to how rainbows are formed, as different wavelengths of light are bent at varying angles, creating a spectrum of colors. The inner ring appears blue, the middle ring yellow, and the outer ring red due to this refractive process. This visual effect is often referred to as a moon halo. Understanding this can enhance appreciation for the beauty of such natural occurrences.

I was staring at the moon last night and noticed that as the clouds passed next to the moon a ring of color would surround the moon. The inner ring (closest to the moon) was blue. The middle ring looked yellow. And the outer ring looked red. It looked so cool! But i have no idea why this was happening. Could anyone explain this phenomena?

And please excuse my ignorance. Thank you!

It's the same basic phenomenom that causes a rainbow. Water droplets (or possibly ice crystals) in the atmosphere refract the light from the moon, and since the index of refraction is a function of wavelength, different frequencies get refracted by a different amounts, so the white light from the moon gets split into colors.
 
I was thinking it was linked to the same concept behind a rainbow but wasn't entirely sure. Thanks a lot phyzguy
 

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread '3I/ATLAS, Interstellar Comet'

3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
