Gas Giant Exoplanets Close To Parent Stars
2013-06-28 09:34:28

redOrbit Staff & Wire Reports - Your Universe Online Results from the Gemini Observatory's recently completed Planet-Finding Campaign, the most extensive direct imaging survey to date, reveal the outlying orbital space around many types of stars is largely devoid of gas-giant planets, which appear to remain close to their parent stars. The findings could have a significant impact on theories of planetary formation. "It seems that gas-giant exoplanets are like clinging offspring,"...

Voyager 1 Still Within The Confines Of Solar System
2013-06-27 15:36:08

Lee Rannals for redOrbit.com - Your Universe Online Scientists are split on exactly where NASA's Voyager 1 spacecraft is sitting within the Solar System, but new research from the space agency suggests it is on the last frontier out. A team of scientists wrote in Geophysical Research Letters in March that the spacecraft had already left our Solar System. However, the latest intel from NASA shows that the spacecraft is still sitting just within the edge of our "Solar Bubble."...

Asteroids Found To Have Similar Orbit To Uranus
2013-06-19 04:44:21

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In 2006, Uruguayan astronomer Tabaré Gallardo provided evidence that two asteroids, Crantor and 2000 SN331, had orbital periods similar to that of the planet Uranus — roughly 84 Earth-years. Now, some seven years later, researchers Carlos de la Fuente Marcos and Raúl de la Fuente Marcos, at the Complutense University of Madrid (UCM), have confirmed that not two, but three large asteroids...

Venus Express Observes Strenghtening Winds On Second Planet From Sun
2013-06-18 15:11:30

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency's (ESA) Venus Express spacecraft has revealed that the winds on the second planet from the Sun have been getting faster over the last six years. Venus holds a super-rotating atmosphere that is able to whip around the planet once every four Earth days. Scientists are able to monitor patterns in the long-term global wind speeds by tracking the movements of distinct features in the clouds of the planet....

Comet Lovejoy Provides Rare Data
2013-06-07 14:36:43

Lee Rannals for redOrbit.com - Your Universe Online The intrepid comet Lovejoy flew right into the Sun's violent atmosphere and lived to tell scientists the story and help them understand more about our local star. In December 2011, comet Lovejoy plowed into the Sun's atmosphere, withstanding temperatures that would have obliterated any man-made object. Telescope images taken of the comet's miraculous feat showed how the comet's tail was pulled about by an intense magnetic field. This...

Researchers Look At Hot Jupiters And Planetary Migration
2013-06-07 07:20:56

April Flowers for redOrbit.com — Your Universe Online Stars have an alluring pull on the planets that surround them, especially a class of planets known as hot Jupiters. These planets are gas giants that form farther from their stars before migrating inward and heating up. Hot Jupiters, despite their close-in orbits, are not regularly consumed by their stars, as a new study conducted with data from NASA´s Kepler Space Telescope reveals. These planets remain in fairly stable...

Dust Trap Around Young Star Is A ‘Comet Factory’
2013-06-06 13:01:43

Lee Rannals for redOrbit.com — Your Universe Online Astronomers writing in the journal Science say they have captured an image of a comet factory around a young star. The team found a region around a young star where dust particles can grow by clumping together, giving the scientists the first clear observation of a long-standing mystery of how dust particles in disc grow to larger sizes that eventually form comets, planets and other rocky bodies. Scientists do not fully...

The Sun Was A 'Feisty' Character In Its Younger Days
2013-06-06 12:57:33

Lee Rannals for redOrbit.com — Your Universe Online Astronomers said during a press conference at a meeting of the American Astronomical Society that when our Sun was in its infancy, it was active and "feisty." The team said that when the Sun was young it was growing in fits and burping out bursts of X-rays. They came to this conclusion after studying another young star in our galaxy known as TW Hydrae, which sits about 190 light-years away in the southern constellation Hydra the...

Electrifying Exoplanets With Stellar Winds
2013-06-04 11:10:37

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online When scientists began seeking out planets outside of our solar system, they anticipated seeing systems much like our own. Small, rocky worlds orbiting a couple of astronomical units from the host star, with the gas giant planets orbiting farther out. After all, much effort had been given to explaining how a solar system such as ours would form. Only, this is not what has been found. Many solar systems are constructed...

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.
