NASA has recently released an intriguing photo of sand dunes on Mars. It shows blue dunes on the so-called Red Planet. Although it’s a false-color image, it still looks surreal and captivating, and the story behind it is pretty interesting.
The Northern Lights are on many people’s bucket lists. The celestial phenomenon occurs in the upper levels of our atmosphere. We’ve long sought explanations for these beautiful lights, and extensive research has come up with many answers. We thought we had it all covered until something strange happened. Recently, in Finland, a scientist discovered a new type of Aurora.
Each Aurora we see has a classification, it makes it easier to describe. For example, these ripples and waves of light got a cool-sounding label like ‘corona’, which describes an Aurora straight above us. The one that appears as if it’s falling straight down. This new observation, labelled ‘dunes,’ was discovered by citizen-scientist Pirjo Koski and her team in Finland.
