this beautiful photo of Earth from above makes me wonder when we’ll discover another habitable planet. And when we’ll visit it. And how it will look like 💭 A new study by NASA suggests there are 300 million planets in the observable universe capable of hosting life, and at least four of them are within 20-30 light years from Earth 🏝 (the Moon is 1.25 light seconds away and Mars is in 12.5 light minutes) Well, we have to speed up to get there 💫 #clouds #planeview #sunset #fromabove #space #nasa #cloudsfromabove #cloudporn #cloudscape

bonsoir

This is me thinking of extraterrestrial oceans. Inspired by last week’s breaking news (NASA found water on the sunlit surface of the Moon. Well, only 12 oz per cubic meter, but still 😂)

The weather forecast says yesterday was the last summer day this year and I’m finally sharing some summer’20 highlights ✨ #staycation2020

I’ve always been a sunset fan (especially when it’s golden) and have never thought why the sky color changes. Only when I heard about blue sunsets on Mars, I learned why our sunsets are golden, pink or red. So, white light comes from the Sun and passes through the atmosphere, which consists of gases and particles. This white light is composed of all colors of the visible spectrum (violet, indigo, blue, green, yellow, orange, red). Each color has a certain wavelength—violet has the shortest, red has the longest wave. The molecules of the air are much smaller than light waves, so the light can easily pass through them and reach the earth surface. However, particles in the air can scatter (reflect and redirect) some blue and violet waves, hence blues and violets are sent in multiple directions all over the sky and during the day the sky is blue (well, we would see it as violet if our eyes were more sensitive to this color). During the sunset, when the sun is closer to the horizon, the sunlight has to travel a longer distance through the atmosphere. So more blue and violet waves are scattered away by multiple scattering events, resulting in only colors from another side of the spectrum remaining in sun beams (red, orange, yellow). #sunset #sea #seaview
