New studies in astrophysics bring an unexpected result. Stars with high metalicity have fewer stellar companions. The research was conducted at the Australian National University and the University of New South Wales and could help in the search for stars that have Earth-like planets.The metalicity is a scientific te... |

A new X-ray telescope is prepared by the European Space Agency, to further study the origins of the Universe. XEUS or X-ray Evolving Universe Spectroscopy aims to study the fundamental laws of the Universe, the formation and evolution of supermassive black holes and the galaxies. XEUS will be 30-50 times more sensiti... |

Astronomers have just found an unusual blue halo around a distant star that looks like a glowing cosmic needle. This enlarged debris disk could point at hidden planets, since it is a well-known fact that they are leftovers from planet formation processes.The young star is called HD 15115, observed using NASA's ... |

Astronomers have recently analyzed the chemical composition of distant stars and discovered intriguing evidence of pollution on their surface, caused by the planets orbiting them. It seems that dwarf stars display iron enrichment on their surface, most likely caused by planetary debris thrown in space and falling o... |

We like to think highly of ourselves, in particular but also in general. The human race did this, the human race did that, we could someday go, become, explore... But most people never really realize how insignificant the Earth really is in the grand scheme of the Universe.If we compare Earth's size with that o... |

Landing at high enough speeds on sandy planets could sink the landing module deep in the sand layer, just like a rock diving into a pool. This is the conclusion of a new study that considered the problem of sand on other planets and how that could affect future manned missions to the Moon and Mars.Both Mars and the M... |

It's been years since NASA last heard from either of its two Pioneer probes hurtling out of the solar system, but scientists are still debating the source of an odd force pushing against the outbound spacecraft.A new study of the "Pioneer anomaly" suggests that there is an unknown but conventional force acting ... |

Finding planets orbiting stars at great distances from our solar system is not an easy job, but there seems to be many of them out there, according to recent observations. And that's a great thing, since it's actually harder than finding a needle in a hay stack. It's more like looking for a firefly fly... |

NASA's James Webb Space Telescope (JWST) is a planned space infrared observatory, intended to be a significant improvement on the aging Hubble Space Telescope, which is about to be decommissioned, after successfully serving its purpose since 1990. The agency is considering equipping the telescope with a grapple... |
