Alpheratz and Polaris appear bright because they are both luminous supergiant stars. Alpheratz is a binary star system, with one of the stars being a supergiant, while Polaris is a Cepheid variable star. These types of stars are much larger and hotter than the Sun, emitting a significant amount of light and making them appear bright in the night sky. Additionally, their relatively close proximity to Earth also contributes to their brightness. **

To descale the Polaris fully automatic coffee machine, you will need to use a descaling solution specifically designed for coffee machines. First, prepare the descaling solution according to the manufacturer's instructions. Then, pour the solution into the water tank of the coffee machine. Next, run a descaling cycle as per the machine's manual, which will involve the machine pumping the solution through its internal system. Finally, rinse the water tank and run a few cycles of plain water through the machine to ensure all the descaling solution is flushed out. **

Trees are not blue because they contain pigments that absorb certain wavelengths of light and reflect others. The pigments in trees, such as chlorophyll, reflect green light, giving them their green color. Blue light is absorbed by the pigments in the leaves, so very little blue light is reflected, resulting in the leaves appearing green to our eyes. Additionally, the structure of the cells in tree leaves and bark also contribute to the way they interact with light, further influencing their color. **
