redOrbit Staff & Wire Reports - Your Universe Online A team of astronomers have identified what is believed to be the sibling of our sun – a star thought to have been born from the same cloud of gas as the one that provides our solar system with light and warmth. According to Deborah Netburn of the Los Angeles Times, the sun’s so-called long-lost brother is slightly bigger and has a somewhat hotter surface temperature than the star around which the Earth orbits. However, an...

Cluster Helps To Model The Mysterious Magnetosphere Of Earth
2014-05-09 03:10:38

ESA For many years, scientists have been striving to understand the constantly changing structure and behavior of the huge magnetic bubble that surrounds our planet. One approach – pioneered by Russian scientist Nikolai Tsyganenko - has been to develop models based on data sent back by spacecraft, such as ESA's Cluster quartet. As Earth sweeps around the Sun, it is constantly bombarded by energetic particles from solar storms and deep space. Fortunately, the planet generates a...

redOrbit Staff & Wire Reports - Your Universe Online A team of 74 scientists from 18 countries, mostly working on an unpaid volunteer basis, have mapped and catalogued nearly 200,000 glaciers, creating the first-ever global inventory of icebergs and ice floes. The catalogue, which was compiled as part of the Randolph Glacier Inventory (RGI) project, includes information about locations and size. It will allow for calculations of volume, as well as their ongoing contributions to...

Upcoming Camelopardalid Meteor Shower Could Rival The Perseids
2014-05-21 08:00:12

[ Watch the Video: ScienceCasts - NASA On The Lookout For A New Meteor Shower ] Brett Smith for redOrbit.com - Your Universe Online May isn’t exactly known for its meteor showers. In fact, this month’s Camelopardalid meteor shower, caused by dust from periodic comet 209P/LINEAR, has technically never even been seen before. However, astronomers have predicted that May 2014 could see a Camelopardalid meteor shower that rivals the year’s biggest display – the Perseids of August....

Halleys Comet Meteor Shower
2014-05-05 11:12:27

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online As comets hurtle into the inner part of the solar system, the Sun’s radiation causes two tails to emerge. The first is primarily gas, vaporized by the heat of our star’s intense, warming rays. But while this glowing streak is what provides the visual imagery we normally associate with comets, it quickly fades as the comets moves across the solar system. In contrast, the second tail is formed by the pressure of the solar...

Uranus
2014-05-02 04:00:57

NASA/JPL NASA's Cassini spacecraft has captured its first-ever image of the pale blue ice-giant planet Uranus in the distance beyond Saturn's rings. The robotic spacecraft briefly turned its gaze away from the ringed beauty of Saturn on April 11, 2014, to observe the distant planet, which is the seventh planet from the sun. The planets Uranus and Neptune are sometimes referred to as "ice giants" to distinguish them from their larger siblings, Jupiter and Saturn, the classic "gas...

Ganymede

redOrbit Staff & Wire Reports - Your Universe Online While astronomers have long believed that Jupiter’s moon Ganymede was home to a thick ocean sandwiched between two layers of ice, a new NASA-funded research project now claims that the largest natural satellite in our solar system could actually have several layers of ice and ocean stacked one upon another. Writing in the journal Planetary and Space Science, Steve Vance of the Jet Propulsion Laboratory (JPL) in Pasadena,...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...
