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...

NASA Invites You To Fly Along With Voyager
2013-04-25 09:01:15

NASA's Jet Propulsion Laboratory A gauge on the Voyager home page tracks levels of two of the three key signs scientists believe will appear when the spacecraft leave our solar neighborhood and enter interstellar space. When the three signs are verified, scientists will know that one of the Voyagers has hurtled beyond the magnetic bubble the sun blows around itself, which is known as the heliosphere. The gauge indicates the level of fast-moving charged particles, mainly protons,...

Monitoring Elusive Collisions In Space
2013-04-24 06:09:40

April Flowers for redOrbit.com - Your Universe Online Asteroids and other objects in our solar system collide often, but researchers are not always able to detect or track such impacts from Earth. This means that we are sometimes caught unaware by the "rogue debris" created by the impacts. New research from the University of California, Los Angeles, has devised a method to monitor these types of collisions in interplanetary space. The team used a new method to determine the mass of...

Improving The Mathematical Method For Simulating Solar System Evolution
2013-04-12 04:57:04

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online It seemed that that we had everything worked out. Astronomers modeled the creation and evolution as the collapse of a giant solar nebula. As the central star formed, the radiation then influenced the formation of the planets — rocky planets dominating the inner sanctum, while the larger gas giants naturally populated the orbits further out. All of this was then encased in a spherical swarm of icy bodies known as...

Saturn’s Moon Telesto Discovered 33 Years Ago Today
2013-04-08 18:47:23

Lee Rannals for redOrbit.com — Your Universe Online Thirty-three years ago today, astronomers discovered Saturn's moon Telesto using ground-based observations. Astronomers Bradford A. Smith, Harold Reitsema, Stephen M. Larson and John W. Fountain were performing ground observations on April 8, 1980 when they discovered the Saturn moon. The moon was officially named after Telesto of Greek mythology, but was also designated as Saturn XIII or Tethys B. NASA said Telesto is known...

NASA Scientists Find Striking Similarity Between Moon And Asteroids
2013-03-26 07:24:40

Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists from NASA´s Lunar Science Institute (NLSI), along with researchers from abroad, have discovered that Earth´s own natural satellite shares a striking similarity with Vesta, and perhaps other large asteroids roaming around the Solar System. The Moffett Field, California-based NLSI found that the same population of high-speed projectiles that bombarded the Moon four billion years ago, also impacted the giant...

Europe-Sized Storm On Venus Monitored By Astronomers Via ESA Spacecraft
2013-03-25 12:47:52

Lee Rannals for redOrbit.com — Your Universe Online Astronomers writing in the journal Nature Geoscience say they have been closely monitoring the movement of a huge whirlwind the size of Europe on Venus. Researchers from Universidad del Pais Vasco (UPV) used an instrument on board the European Space Agency's (ESA) Venus Express spacecraft to monitor the evolution of the south pole vortex. The team monitored the movement of the vortex on two separate main cloud levels in Venus'...

Voyager 1 Continues Its Journey
2013-03-20 14:16:43

Lee Rannals for redOrbit.com - Your Universe Online NASA´s Voyager 1 spacecraft may have allegedly left the confines of our solar System after 35 years and more than 11 billion miles of traveling through space. Scientists writing in the Geophysical Research Letters claim that they measured drastic changes in radiation levels on August 25, 2012 while the spacecraft was sitting over 11 billion miles away from the Sun. The anomalous cosmic rays (those trapped in the outer heliosphere)...

On March 17, 2013, MESSENGER successfully completed its year-long first extended mission in orbit about Mercury, building on the groundbreaking scientific results from its earlier primary mission. Today the team is poised to embark on a second extended mission that promises to provide new observations of Mercury's surface and interior at unprecedented spatial resolution and of the planet's dynamic magnetosphere and exosphere at high time resolution during the peak and declining phase of the...

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.
