'tis a nebula |

it looks amazing so I'm not gonna say shit about it, but it's not pony related |

Ponies are of the universe. |

I'm no astronomer but is that the horsehead nebula |

The present Observable Universe appears to be "only" 13.7 billion years old. Before that, we do not know that the universe was like (if it even existed) because it would have been in a state that we cannot perceive.
It appears that the rate of expansion of space is increasing. IF (a big if) this increase continues forever, this means that expansion will proceed faster and faster, until the rate of expansion, even in small objects, exceeds the capacity of the forces to keep things together. This will take trillions of years, but there would come a time when molecules would not be able to stay together, then (maybe quadrillion years) even atoms, and eventually not even subatomic particles (that is because space expands EVERYWHERE at once, even inside atoms). Quadrillion years may sound like a long time, but it is still exactly 0% of "forever". |

Stars form by the gravitational collapse of interstellar gas. This gas in normally in the form of a molecular cloud which is about 75% Hydrogen, such as the Orion nebula. The process that triggers star formation is not well known but it might be supernova or the shocks form the formation of other stars.
As the cloud collapses a number of things happens, the cloud heats up due to the release of gravitational energy and the conservation of angular momentum ensures that the cloud forms a flatted disc - the accretion disk. The cloud has a large scale magnetic field which due to it's massive size has field lines that appear perpendicular to the disk. The hot material in the disk get thermally lifted into the field, this causes the field to become coiled like a spring. The material trapped within the field lines is accelerated out in the form of a bipolar jet (about 99% of the material that ends up in the disk will be ejected) , this imparts a negative torque on the disk allow the remaining accrerate onto the proto-star. Inside the protostar the increased mass and gravitational energy heats the core. At some stage a brief phase of Lithium and deuterium fusion will occur but this is very brief. Once the core reaches 15million K nuclear fusion of hydrogen occurs (the exact details are mass dependent) and the star enters the main sequence - it becomes an adult. It's nebula is dispersed ,it's jets have previously ceased |

Mother nature was into ponies before it became popular. |
