The water that covers over 70 percent of the Earth formed just 14 million years after the formation of the solar system – much earlier than previously believed, according to a new study published online Friday in the journal Science.

New Evidence Suggests Mercury Was Formed From A Stellar Collision

Planet Mercury has an unusual metal-rich composition which has baffled the scientific community. However, new evidence may have solved this mystery.

How do solar systems form? Specifically, why do some systems form smaller rocky worlds, while others are dominated by gas giants? A recent study led by Trey Mack, a graduate student in astronomy at Vanderbilt University, may have found the answer.

Moon-Forming Impact Dated

Using a new method for estimating the moon’s age, an international team of planetary scientists has determined that the satellite formed nearly 100 million years after the formation of the solar system, according to research published Thursday in the journal Nature.

Earthen Crust Oxygen Got Its Start During Creation Of Solar System
2013-10-25 07:03:56

In the oldest, most pristine rocks, oxygen -- the most abundant element in the Earth's crust -- follows a strange, anomalous pattern that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth.

Trojan Asteroids Are More Common Than Previously Believed
2013-08-30 05:06:06

The first Trojan asteroid sharing the orbit of Uranus has been discovered by University of British Columbia astronomers who believe the asteroid - 2011 QF99 - is part of a larger-than-expected population of transient objects temporarily trapped by the gravitational pull of the solar system's giant planets.

Super-Jupiter Planet Observed By Astronomers Using the Subaru Telescope
2013-08-06 05:23:10

There are several techniques employed by astronomers to discover planets orbiting distant stars. The most popular techniques seek transits - where a planet will pass directly in front of a star, blocking part of its light.

Complex Origins Of Solar Systems
2013-07-25 11:12:46

Research has led to a new theory that may explain the complex and differentiated origins of solar systems.

Sand Grains In Meteorite May Have Come From Milky Way-Forming Supernova
2013-04-21 07:31:06

Two tiny grains of silica discovered in primitive meteorites may have originated from the ancient supernova responsible for the formation of the solar system, according to new research published in the May 1 edition of Astrophysical Journal Letters.

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...
