  Charlottesville VA (SPX) Dec 21, 2018 As comet 46P/Wirtanen neared Earth on December 2, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a remarkably close look the innermost regions of the comet's coma, the gaseous envelope around its nucleus. ALMA imaged the comet when it was approximately 16.5 million kilometers from Earth. At its closet on December 16, the comet - one of the brightest in years - was approximately 11.6 million kilometers from Earth, or about 30 times the distance from the Earth to the ... read more |

NASA's New Horizons spacecraft is bearing down on Ultima Thule, its New Year's flyby target in the far away Kuiper Belt. Among its approach observations over the past three months, the spacecraft has been taking hundreds of images to measure Ultima's brightness and how it varies as the object rotates.
Those measurements have produced the mission's first mystery about Ultima. Even though sc ... more |

 Washington DC (Sputnik) Dec 21, 2018 
A new study by NASA scientists has proven that sugar molecules - one of the building blocks of life - can form in conditions similar to those in outer space. The find provides further grist to the mill of the argument that life on Earth got some sort of help from above in its formation.
A new paper published on Tuesday by scientists from the National Atmospheric and Space Administration's ... more |

This image shows what appears to be a large patch of fresh, untrodden snow - a dream for any lover of the holiday season. However, it's a little too distant for a last-minute winter getaway: this feature, known as Korolev crater, is found on Mars, and is shown here in beautiful detail as seen by Mars Express.
ESA's Mars Express mission launched on 2 June 2003, and reached Mars six months l ... more |

New research from University of Alberta physicists provides the first-ever model of our Moon's rotational dynamics, taking into consideration its solid inner core. Their model helps to explain why, as seen from Earth, the Moon appears to wobble on its axis.
The answer, said physicist Mathieu Dumberry, lies in the complex geometry of the Moon's orbit, locked in what is known as a Cassini st ... more |

Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench, a crescent-shaped trench in the Western Pacific that measures 1,500 miles long and is the deepest ocean trench in the world.
The observations from the trench have importa ... more |

 Hannover, Germany (SPX) Dec 17, 2018 
The detection of Einstein's gravitational waves relies on highly precise laser measurements of small length changes. The kilometer-size detectors of the international network (GEO600, LIGO, Virgo) are so sensitive that they are fundamentally limited by tiny quantum mechanical effects.
These cause a background noise which overlaps with gravitational-wave signals. This noise is always presen ... more |
