In fact, α Centauri consists of three stars — the yellow and orange A and B components and the red dwarf Proxima Centauri. The latter is actually the closest star to us, since it circles around the main components in a very elongated orbit and is now in its closest position to the Su...
Astar, in its simplest form, are giant celestial bodies of gas that generate light, heat and energy through a nuclear reaction. They can be many thousands and millions of times as big as theearth. The nearest star to us isthe Sun, then the binary stars of alpha and proxima centauri. Th...
The two bright stars are (left) Alpha Centauri and (right) Beta Centauri. The faint red star in the center of the red circle is Proxima Centauri. Credit: Skatebiker at English Wikipedia (CC BY-SA 3.0) You have to be careful, though, sometimes stars just happen to be beside each other...

Surely, the power to travel instantaneously from New York to Bangkok or from Earth to Alpha Centauri is certainly a power worth grasping after. It could ultimately guarantee the survival of the human race and its peripheral technologies could change fundamentally what it is to be human. After ...
Let me explain: when a star dies, the leftover materials can go on to recreate a new star somewhere. An exploding star is believed to be what caused the creation of the Solar System, but more on that later. Whilst most nebulas are invisible to the naked eye, it is possible to just ...
