In many places in Flanders, people looked up at the sky in amazement last night. The sky turned pink and here and there even bright red. Sometimes there was only a red stripe in the cloud cover. We received a lot of pictures via the 4040. But where did that fiery sky come from? And why did she suddenly look so amazing? we asked science journalist Martin Peters.
Sunlight is made up of all the colors of the rainbow. But that doesn’t mean that the same amount of each color ends up in our eyes,” Peters says. “When the sun goes down or up, the light has to cover a greater distance. As a result, the oxygen and nitrogen molecules in the air filter out almost all of the blue light. What’s left at the end are the warmer tones like yellows, oranges, and reds.”

But the weather photo, for example, can make the sunrise brighter. “One of the most important elements is clouds,” Peters continues. Ice crystals and water droplets in medium and high clouds reflect sunlight, creating a breathtaking scene. Suddenly the whole sky was on fire as we saw yesterday in several places. For best results, the sky should be slightly to severely cloudy with a clear horizon. Sometimes a cloud on the horizon can partially let the sunlight through. Then only part of the cloud cover gets illuminated and you get this red band in the clouds, for example. “
Wind can help too. “Not only does it create beautiful patterns in the cloud cover, but it also, along with the rain, causes many of the particles floating in the air to disappear. As a result, those particles no longer obscure our vision. If they are gone after a good breeze or rain-rain Warmer tones reach us and everything seems brighter.”
