The solar system's smallest planet has been shrinking at an unexpected rate, researchers announced on Thursday. tags mercury shrinking planet mariner shrinkWhen NASA's Mariner 10 probe flew by Mercury in 1974 and 1975, it returned images of strange cliffs called 'scarps' that cut across all sorts of geological formations. That suggested that the planet's surface has contracted over time. picked by AutumnLotus 5 months ago |

A NASA probe has begun beaming back stunning new images from its successful second flyby of Mercury, the planet closest to the sun. NASA's MESSENGER probe captured never-before-seen views of the Mercury during its encounter on Monday. picked by AutumnLotus 2 months ago 0 comments edit related share science |
Craters come in all shapes and sizes, some more bizarre than others. Recent photos of Mercury have revealed two new categories of crater that scientists are puzzling over how to explain. When NASA's MESSENGER spacecraft flew by the planet Jan. 14 it snapped pictures of several craters with strange dark halos and one crater with a spectacularly shiny bottom. picked by AutumnLotus 9 months ago 2 comments edit related share science |
A whole new side of Mercury has been revealed in pictures taken by NASA's MESSENGER probe, which flew by the tiny planet two weeks ago in the first mission to Mercury in more than three decades. The photos, released today, include one of a feature the scientists informally call "the spider," which appears to be an impact crater surrounded by more than 50 cracks in the surface radiating f... read full post picked by AutumnLotus 10 months ago 0 comments edit related share science |

Chondritic meteorites have a similar chemical composition to the sun and are therefore reliable witnesses as to what the solar nebula, from which the planets formed, was composed of. This can be used to deduce what the Earth consists of chemically. However, ETH Zurich researchers have now discovered that strictly speaking this fundamental geological assumption is not true. picked by AutumnLotus 7 months ago 1 comments edit related share science |
Astronomers have discovered what may be the smallest alien planet yet — a rocky ``SuperEarth'' only four times heavier than our home planet. picked by AutumnLotus 6 months ago 2 comments edit related share science |
The hottest planet ever discovered is charcoal black and makes even some stars seem cool. Scientists think the exoplanet absorbs nearly all the starlight that reaches its surface and then reradiates it back out into space as heat. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
The new definition, proposed this week by the International Astronomical Union (IAU), basically says every round object orbiting the sun is a planet, unless it orbits another planet. Asteroid Ceres will become a planet. Pluto's moon Charon will become a planet, things could get really strange. picked by Jaxomlotus 2 years ago 0 comments edit related share science |
New scientific evidence suggests that deep inside the planet Mercury, iron “snow” forms and falls toward the center of the planet, much like snowflakes form in Earth’s atmosphere and fall to the ground. The movement of this iron snow could be responsible for Mercury’s mysterious magnetic field. picked by AutumnLotus 7 months ago 1 comments edit related share science |

Scientists at the Max Planck Institute for Astronomy in Heidelberg have discovered the youngest known extrasolar planet. Its host star is still surrounded by the disk of gas and dust from which it was only recently born. This discovery allows scientists to draw important conclusions about the timing of planet formation. picked by AutumnLotus 11 months ago 0 comments edit related share plime.com |
Scientists are sifting through their first new views of the planet Mercury in more than three decades thanks to images beamed home by NASA's MESSENGER probe. The car-sized spacecraft zipped past Mercury in a Monday flyby and is relaying more than 1,200 new images and other data back to eager scientists on Earth. picked by AutumnLotus 11 months ago 1 comments edit related share science |

Researchers have dated the earliest step in the formation of the solar system - when microscopic interstellar dust coalesced into mountain-sized chunks of rock - to 4,568 million years ago, within a range of about 2,080,000 years. The dates established by analyzing a particular type of meteorite, called a carbonaceous chondrite, which represents the oldest material left over from the formation of ... read full post picked by AutumnLotus 12 months ago 0 comments edit related share plime.com |

Two rocks found together in Antarctica are chunks of a dwarf planet that was smashed apart early in the solar system's history, detailed studies suggest. Other remnants of the proto-world may still be floating around in the asteroid belt, and might be identifiable by the spectrum of the sunlight they reflect. picked by AutumnLotus 9 months ago 2 comments edit related share science |
