What? How? Why?

Three questions that are important every day in the life of a scientist

As an astronomer, I am very lucky to have the universe as my laboratory. But what are astronomers actually doing? It always sounds like we don't keep our feet on the ground but only think about the universe. Many astronomers look at stars, or many stars together, like galaxies, but I am different. I don't look at stars, but at planets. Actually I truly love all planets in our solar system, especially the Earth. But during my normal days, I am actually looking for planets that contain life, just like the Earth. But how do we know if there is life on other planets? Why is the sky blue? How do rainbows form? During my research I will come across these and many more questions by looking at the Earth. Do you like to know some of the answers, or just want to know how the life of a researcher looks like? I will share my experiences and answers to some of the most interesting questions with you.
