Non est ad astra mollis e terris via

Non est ad astra mollis e terris via. The trip from the earth to a star is not an easy one. This reminds me of a star which is about to explode. Eta Carinae. It's a huge star, and so heavy, that it can't barely carry it's on weight. It's luminosity is about 4 million times that of the Sun and it's the heaviest star yet discovered. Since it's so heavy, it will probably explode into a Supernova (plural: supernovae). Supernovae occur most likely once 50 years in a solar system as large as The Milkyway. When Eta carinae would explode, it would be so bright, that people could read a book with it by night!

Now, to bring ourselves to another subject, I saw something when I was searching the internet for a better explanation (for Supernovae), I saw something that pulled my attention; the star(s) Sirius. It's a star, followed or pulled by another (smaller ''star'', actually a white dwarf). Together they are the brightest star the naked human eye can see. In holland, we call it: 'de Poolster', because in early days it was used for navigation. I find it really interresting because the white dwarf directs the orbit of the ''big star'' and the big star directs the orbit of the white dwarf.

If you have any questions, feel free to ask them! I have written enough for now, bye!
