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...

Free Trip To The International Space Station Won By UCF Experiment
2012-11-29 17:07:12

University of Central Florida A University of Central Florida experiment that could help explain how planets formed in our solar system has won a free ride to the International Space Station in 2013. Physics professor Joshua Colwell´s experiment is one of eight winners of the Space Florida International Space Station Research Competition sponsored by Space Florida and NanoRacks. Space Florida is Florida´s spaceport authority and aerospace development organization. NanoRacks is...

Asteroid Belts Are Good For Life
2012-11-01 14:47:52

Lee Rannals for redOrbit.com - Your Universe Online A new study published in the Monthly Notices of the Royal Astronomical Society suggests the size and location of an asteroid belt may determine whether life can evolve on a planet. An asteroid belt helping to play a role in the development of life may seem counterintuitive, as most view asteroids tend to destroy life. However, the latest study suggests that it is necessary for complex life. The scientists say that the asteroid belt,...

Solar System Shaped By Stellar Shockwaves
2012-09-28 08:20:29

Lee Rannals for redOrbit.com - Your Universe Online Shockwaves emitted by our young sun in its early days would have caused the planets in our solar system to form, according to research presented at the European Planetary Science Congress. Astronomers modeled the movements of particles in fluids and gases in the gas cloud from which our Sun accreted. Their work suggests that during its early days, the Sun emitted a series of shockwaves that rippled out into the remaining material....

Newly Discovered Mineral Provides Clues To Evolution Of Solar System
2012-06-27 09:42:28

Lawrence LeBlond for redOrbit.com A previously unknown mineral has been found in a meteorite that fell to Earth in 1969, according to a Caltech geologist who has been studying the meteoric sample since 2007, and who has also found eight other new minerals in the sample. The Allende meteorite was among thousands of meteorites that lay scattered about the state of Chihuahua, in Mexico, after a meteor exploded over the region in 1969. More than 40 years later, the meteorite is providing...

Image 1 - Exoplanet-Consuming White Dwarf Stars Discovered
2012-05-03 10:19:16

Astrophysicists at a UK university have found a quartet of white dwarf stars which they say are in the process of consuming exoplanets that were once similar in composition to Earth. According to a Thursday press release, researchers from the University of Warwick said that the four stars which they observed were surrounded by dust from shattered planetary bodies. They used the Hubble Space Telescope to survey the chemical composition of those stars' atmospheres, and discovered that the...

Earth could be as much as 70 million years younger than scientists originally believed, according to a new study which claims that it could have taken the planet 100 million years to reach its current size instead of the widely believed 30 million years. Dr. John Rudge, a research fellow at the University of Cambridge's Trinity College, along with an international team of experts, compared geochemical information originally found in the Earth's mantle and compared it to the same material from...

For decades, researchers have been puzzled over the origins of Saturn's baby moons, which, according to many models, are so small that they should have been blown to pieces long ago by impacts with asteroids and comets. But a group of researchers from France and Britain now think they have the answer. Saturn's icy rings might have given birth to the planet's odd-shaped, small moons, scientists now believe. Scientists theorize that these unusual moons, some of which resemble flying saucers,...

The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approx. 4,537 million years ago. But new research from the Niels Bohr Institute shows that the Earth and Moon must have formed much later "“ perhaps up to 150 million years after the formation of the solar system. The research results have been published in the scientific journal,...

Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...

Solar Nebula -- In astronomy, the solar nebula is the gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. In 1755 the German philosopher Immanuel Kant suggested that a nebula in slow rotation, gradually pulled together by its own gravitational force and flattened into a spinning disk, gave birth to the Sun and planets. A similar model, but with the planets being formed before the Sun, was proposed...

Solar System
2012-10-22 06:09:41

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
