After a journey that lasted more than seven years, NASA’s Dawn spacecraft has entered its approach phase around Ceres as it prepares to become the first spacecraft ever to visit the Texas-sized dwarf planet.
Ever wonder what the formation of an asteroid crater on Earth would look like if viewed in slow-motion? Researchers from the University of Minnesota have found a unique way to model such an event by recording the impact of raindrops on sandy surfaces.
As space enthusiasts bid farewell to a year that saw a probe land on a comet for the first time and the discovery of active organic chemistry on Mars (among other things), the Universe has gone to great lengths to ensure that the transition from 2014 to 2015 will be a spectacular one.
In Christian tradition, the Star of Bethlehem guided the magi to the town of Bethlehem, where they meet the baby Jesus and present him with gifts of gold, frankincense and myrrh – but what was this light that guided them, and is there astronomical truth to its Biblical appearance?
Don’t look now, Milky Way, but it appears that there’s a new dwarf galaxy in the neighborhood.
These scientists are guaranteed to have a white Christmas.
The British Geological Society issued a geomagnetic alert regarding incoming atmospheric disturbances resulting from recent Coronal Mass Ejections from the sun, projected to arrive at Earth on
Benton Harbor Technology Center is one of company's largest focused on next-generation processes BENTON HARBOR, Mich., Dec. 19, 2014 /PRNewswire/ -- Jeff M.
RedOrbit sits down with Pat McCarthy, director of the Giant Magellan Telescope Organization, to discuss stargazing on the shortest day of the year (in the Northern Hemisphere).
Spectacular to look at, but poorly understood, auroras have been somewhat of a conundrum for scientists. But new data from NASA and ESA satellites has finally shed, ehem, light on one particular type of very high-latitude aurora.
The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...
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...
Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...
The Tropic of Capricorn, alternately called the Southern Tropic, is a marker of the most southerly latitude on the Earth at which the Sun can be directly overhead. This occurs at the December solstice, when the southern hemisphere is tilted towards the sun at its maximum degree. It is one of the five major circles of latitude that mark maps of the Earth. It presently lies 23 degrees 26’ 16’’ south of the Equator. Currently, the Tropic of Capricorn is drifting towards the north at...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
