Possible Subsurface Ocean On Saturn Moon Dione
2013-05-30 14:16:58

Brett Smith for redOrbit.com - Your Universe Online Once considered to be an afterthought when it came to Saturn´s moons, scientists now believe Dione likely had an active geological history after analyzing data sent back from NASA´s Cassini spacecraft. "A picture is emerging that suggests Dione could be a fossil of the wondrous activity Cassini discovered spraying from Saturn's geyser moon Enceladus or perhaps a weaker copycat Enceladus," said Cassini team leader Bonnie...

Charting Massive Winds On Gas Giants Of The Outer Solar System
2013-05-17 07:51:59

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Predicting the weather is difficult. With varying pressures, planetary rotation and various other factors, weather systems on Earth border on chaos. But, believe it or not, predicting the weather on the third rock from the sun is rather straightforward compared to predicting the atmospheric motions of the gas giants that lay beyond the asteroid belt. The primary reason is that, unlike Earth, the Jovian worlds do not have...

Moon's Water Supply Came From Earth, Not From Comet Impacts
2013-05-09 13:34:08

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Prior to the Apollo Moon missions, scientists conjectured that the Moon would be extremely dry, that even below the surface of the Magnificent Desolation little or no water would be present. But the rocks brought back by the lunar explorers revealed that the Moon, while still dry compared to Earth, contained a surprising amount of water. Furthermore, the composition of the Moon led scientists to the current Big Impact...

Researchers Shed Light On Why Saturn Looks So Young
2013-04-30 14:52:47

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online At the dawn of our Solar System the planets were very hot, as the energy from their creation lingered. But over time the planets would cool, becoming darker, only occasionally paused in this process by large impacts or radioactive decay. At least that is what we would expect. A mystery that has puzzled scientists for half a century revolves around the appearance of the planet Saturn. The second largest planet in our Solar...

Meteoroids Slam Into Saturn’s Rings
2013-04-25 15:08:34

Lee Rannals for redOrbit.com — Your Universe Online NASA said on Thursday that its Cassini spacecraft provided the first direct evidence of small meteoroids crashing into Saturn's rings. Previously, scientists had only witnessed impacts on Earth, the moon and Jupiter as they occurred. Studying the impact rate of meteorites outside the Saturnian system helps scientists understand how different planetary systems in our Solar System formed. The meteoroids that impacted Saturn are...

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...

Ernst Wilhelm Leberecht Tempel was born on December 4, 1821 in Germany and died March 16, 1889. Tempel worked in Marseille until the onset of the Franco Prussian War in 1870 at which time he relocated to Italy. Tempel discovered or assisted in discovering 21 comets. The Tempel asteroid 3808 and lunar crater Tempel are named in his honor. His most notable discoveries include the following asteroids 564 Angelina, 65 Cybele, 74 Galatea, 81 Terpsichore and 97 Klotho.
