One of the basic things any kid knows about planets is that they spin around a star. What goes without saying is that a planet in fact spins around a single star. Apparently, this is not the case with a recently discovered celestial body, which has an orbit so elongated and tilted, that astronomers believe it's ... |

The asteroid Apophis is one of the most feared and investigated pieces of space rocks in the skies at this point, because astronomers calculated in 2004 that it might be possible for it to hit the Earth in the near future, around 2036. Because the asteroid has twice the size of a football field, a collision with it w... |

When new stars are born, not all material in their precursors gets ignited and consumed. The remains usually start spinning around it, and, over millions of years, new planets are formed. The debris-filled areas around the stars are known as a protoplanetary disk. Astronomers know how long it takes for planets to for... |

In spite of their names, planetary nebulas have nothing to do with planets. Their name comes from the fact that they resembled large exoplanets when viewed through earlier telescopes. They are, in fact, shells of gas and dust, expelled by stars about the size of our Sun when their life cycle ends. Now, astronomers be... |
