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...

Closest Star System In A Century Found 6.5 Light Years Away
2013-03-11 16:28:34

Brett Smith for redOrbit.com - Your Universe Online Using data obtained from a NASA satellite, a Pennsylvania State University astronomer has identified the closest solar system to be found within the past 97 years. According to astronomer Kevin Luhman´s report in the Astrophysical Journal Letters, the newly identified system is a pair of brown dwarf stars and the third-closest system to the Sun. “The distance to this brown dwarf pair is 6.5 light years -- so close that...

Comet PANSTARRS Visible In UK And Irish Skies
2013-03-11 10:00:20

AlphaGalileo Foundation A comet discovered by a Queen´s University Belfast supported project will be visible in UK and Irish skies from tomorrow evening (Tuesday 12 March) onwards. Comet PANSTARRS was discovered in June 2011, by a team including astronomers from the Astrophysics Research Centre at Queen´s, using the Pan-STARRS 1 telescope in Hawaii, when it was still 1.2 billion kilometers from the Sun. The comet will be visible by eye low-down in the Western sky from...

From a news release by NASA, dated February 28, 2013, the Birth of a Planet was observed from Earth through the Hubble Telescope that possibly showed a proto planet being born from a star. Kansas City, MI (PRWEB) March 06, 2013 For much of this century and the previous one, scientists have proposed and theorized about the origins of planets and moons and how they formed; most of the scientific community have settled on the “Accretion” hypothesis for planet formation; which...

Giants Like Jupiter May Have Formed In The Gas Disk Of Young Stars
2013-03-06 06:18:35

Lawrence LeBlond for redOrbit.com - Your Universe Online New research from Carnegie Institution for Science looks at how gas giants similar to Jupiter and Saturn formed and evolved. Using theoretical modeling, lead researcher Alan Boss provides clues that gas giants may form in the presence of gas disks that surround stars in their infancy. The work was recently published in the Astrophysical Journal. By observing young stars that are surrounded by gas disks, Boss demonstrated that...

Comet Siding Spring To Pass Close To Mars In 2014
2013-03-05 20:27:50

Lee Rannals for redOrbit.com — Your Universe Online We've had our fair share of close calls from asteroids recently, but a neighboring planet will soon have its day in the spotlight as a comet grazes past it. Mars will have a front row ticket to comet 2013 A1 as it passes by the Red Planet in 2014, passing within 186,000 miles of Mars, according to NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California. The office even said there is a...

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...
