Sup Travellers?! Have you ever wondered why the sky is blue during the day? The answer is very simple actually. It is because molecules in the air scatter blue light from the sun more than they scatter red light. So the colour of the sky is all about the molecules in the air... mostly. There are a few other factors but this isn't a science course. According to latest reports, Astronomers have discovered the first blue planet that isn't in our solar system but 63 light-years away. It's called HD189733b. Read on.


The planet isn't very Earth-like in all the right ways. It shouldn't be able to support life. The key word here is shouldn't. It's an insanely hot gas giant where glass rains sideways in 4,000mph winds. If life were to be on the planet it would be ripped to shreds by the falling glass. The life forms would have to have an adaptive coating or shell like that of a snail. But the hot gases will melt that away eventually.

What makes the planet blue is the glass in the air. It is that glass, or silicate, that scatters blue light and gives the planet its hue, reports the CBC. So maybe not a great place to visit, but still a milestone discovery, thanks to the Hubble and its Space Telescope Imaging Spectrograph. "Measuring its color is a real first," says one of the researchers. "We can actually imagine what this planet would look like if we were able to look at it directly."

So travellers, if you're planning your next interstellar trip across the galaxies, I won't suggest you visit HD189733b. However it's a great planet to wave at while you're venturing the cosmos. Maybe someone or something may wave back. You never know. Anyway, my name is Trinikid and you've just been informed.
