Comet ISON (C/2012 S1) could very well be the comet of the century. We won't know for sure until it gets close enough to the sun, later this year. In the meantime, astronomers are eagerly awaiting its approach.
Unless they have the Hubble telescope at their disposal, in which case they can get a rather detailed... |

NASA is revealing its findings on the oldest star we know of, so old that it precedes the universe. Obviously, no star can be older than the universe, as far as we know, but the maths suggests that this ancient star is some 14.5 billion years old.
The Big Bang happened 13.77 billion years ago. But there's a ma... |

The Hubble Space Telescope is definitely not in its prime anymore, but it doesn't mean it can't retrieve valuable data.
The deep field image it captured almost two decades ago remains one of the best known astronomical photos in the world. Since then, Hubble has looked at the same patch of sky in even gre... |

Brown dwarfs bridge the gap between small stars and large planets, but are neither entirely. While they don't produce energy, like a star, they were created via the same process as stars. NASA recently pointed both its Spitzer infrared telescope and the Hubble telescope at one particular brown dwarf, the 2MASS... |

Hubble may be the best known space telescope around, the only known space telescope in fact, but it's actually quite old and there are plenty of instruments in space and some even on Earth that can outperform it for some tasks or have a much broader use. But that doesn't mean the venerable telescope is obs... |

Quasars are sometimes created by the supermassive black holes at the center of most if not all galaxies. They are the most luminous objects in the Universe, so far, and they're very important to the understanding of the early Universe in particular, since they can be seen from much farther away than most other o... |
