The sky appears blue due to Rayleigh scattering, where shorter blue wavelengths of sunlight are scattered more than other colors by the atmosphere.
Why Blue Light Scatters More
- Blue light has a shorter wavelength compared to other visible colors, making it more easily scattered by air molecules and small particles in the atmosphere.
- This scattering occurs in all directions, so when you look up, you see blue light coming from every part of the sky.🔗
Why Not Other Colors?
- Red and yellow light have longer wavelengths and pass through the atmosphere with less scattering, which is why the sun appears yellow during the day.
- During sunrise or sunset, sunlight travels through more atmosphere, scattering away most of the blue light and leaving the red and orange hues.🔗

Glacier Lagoon Zodiac Boat Tour: Jökulsárlón, Iceland
During our trip to Iceland, we didn’t make any advance plans for activities. We had a general idea of what we wanted to visit each day and specific times that places were open, but the only set time was when we had to be at our hotels for dinner at the end of the day. Having an open schedule meant we could spend as much, or as little time at each location as we wanted. The one downside was that we had the chance of missing out on something we wanted to do if it was booked up.

7 Guidelines to The Great Window Shade Debate
O nce again, FlyerTalk members debate over the proper etiquette pertaining to window shades aboard airplanes, which has been one of the most controversial topics amongst frequent fliers for many years and has caused as much angst as the debates over armrests and reclining seats: who gets to determine whether the window shade is raised or lowered? Before I impart my 7 guidelines to the great window shade debate, we must first explore some of the reasons as to why this debate is so contentious. Some people believe that certain passengers who occupy window seats are selfish because

I Was Today Years Old When I Learned Why My Sunset Photos Looked “Fine”
I was today years old when I learned that most of the reason my sunset photos looked fine — but never quite right — wasn’t the sunset. It was my phone doing exactly what I told it to do. And me not realizing I was the one giving it bad instructions. I’ve always loved photography. Long before phones had decent cameras, I traveled with an SLR — a Pentax that went with me to places like London and Paris. On my first major trip to Europe, I nearly got myself detained at Charles de Gaulle because I didn’t

Sunday Morning Photograph October 17 2021: An Electrifying Sunrise.
The early autumn morning was less humid but not yet crisp; and yet the change of seasons from a hazy hot summer was in the air. As motorists navigated the roads on their way to work and children walked along the street hauling their books to school in time for their morning classes, they all seemed oblivious as to the brief show which was occurring as a result of both mankind and nature. Sunrises can occur in many different ways, as I mentioned in the Sunday Morning Photograph article last week on October 10, 2021. Some of them have
