Comet 'brighter than the moon' will fly-by the Earth in 2013 By Eddie Wrenn Published: 08:45 GMT, 27 September 2012 | Updated: 13:28 GMT, 27 September 2012 They are one of the most spectacular views a human could hope to see - and next year a comet which could outshine the moon is due to fly by the Earth. Comet ISON is visiting the inner solar system and is set to put on spectacular views for the Northern Hemisphere across November and December as it heads towards the sun. It may prove to be brighter than any comet of the last century - visible even in broad daylight - and this may end up being its one and only trip to the solar system, as its trajectory may see it plunge into the sun in a fiery death.

Massive Storm Pulls Water And Ammonia Ices from Saturn's Depths MADISON, WI — Once every 30 years or so, or roughly one Saturnian year, a monster storm rips across the northern hemisphere of the ringed planet. In 2010, the most recent and only the sixth giant storm on Saturn observed by humans began stirring. It quickly grew to superstorm proportions, reaching 15,000 kilometers (more than 9,300 miles) in width and visible to amateur astronomers on Earth as a great white spot dancing across the surface of the planet. Now, thanks to near-infrared spectral measurements taken by NASA's Cassini orbiter and analysis of near-infrared color signatures by researchers at the University of Wisconsin-Madison, Saturn's superstorm is helping scientists flesh out a picture of the composition of the planet's atmosphere at depths typically obscured by a thick high-altitude haze. The effect, Sromovsky says, is to loft the aerosols found deep in the atmosphere to the visible cloud tops, providing a rare glimpse of normally hidden materials.
Mapping Proportional Geographical Data Reading a blog post by Jon Udell just now - Visual numeracy for collective survival - I came across this question: What do you call th[e] kind of [map] projection, where country size is proportional to a variable? What do you call something like this, for example? Any ideas? 50th Anniversary of Canada in Space 9/24/2012 to 9/30/2012 May 23, 1963: Canada partners with NASA on ionospheric studies Following the success of Alouette, Canada partners with NASA through the International Satellites for Ionospheric Studies (ISIS) program. Canada's ISIS satellites achieved near-perfect performance and orbits — with a high percentage of successful experiments.
Plate Tectonics The Tectonic Globe™ The Plate Tectonic Globe™ The Plate Tectonic Globe™ is a globe unlike any other currently on the market. Its unique hand-crafted design illustrates clearly and accurately Earth's crustal tectonic features in vivid relief. The Plate Tectonic Globe™ captures the essence of Earth's dynamic character by depicting tectonic plate boundaries at mid-ocean ridges, subduction zones, and continental collision zones. Other distinguishing characteristics of The Plate Tectonic Globe™ include raised and indented continental shelves, terrestrial and sea-floor topography, major transform faults, island chains, island arcs, and the relative thickness of continental and oceanic crust - all engineered in hand-sculpted relief.
Go back in time with Street View If you’ve ever dreamt of being a time traveler like Doc Brown, now’s your chance. Starting today, you can travel to the past to see how a place has changed over the years by exploring Street View imagery in Google Maps for desktop. We've gathered historical imagery from past Street View collections dating back to 2007 to create this digital time capsule of the world. If you see a clock icon in the upper left-hand portion of a Street View image, click on it and move the slider through time and select a thumbnail to see that same place in previous years or seasons.
Stripped down: Hubble highlights two galaxies that are losing it A newly released set of images, taken by the NASA/ESA Hubble Space Telescope before the recent Servicing Mission, highlight the ongoing drama in two galaxies in the Virgo Cluster affected by a process known as "ram pressure stripping", which can result in peculiar-looking galaxies. An extremely hot X-ray emitting gas known as the intra-cluster medium lurks between galaxies within clusters. As galaxies move through this intra-cluster medium, strong winds rip through galaxies distorting their shape and even halting star formation. Ram pressure is the drag force that results when something moves through a fluid — much like the wind you feel in your face when bicycling, even on a still day — and occurs in this context as galaxies orbiting about the centre of the cluster move through the intra-cluster medium, which then sweeps out gas from within the galaxies.

Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2012 February 8 Explanation: This moon is shining by the light of its planet. Specifically, a large portion of Enceladus pictured above is illuminated primarily by sunlight first reflected from the planet Saturn. The result is that the normally snow-white moon appears in the gold color of Saturn's cloud tops.
