Experts from Israel, the United States and Japan say that the solar system may have established itself in its current configuration faster than originally calculated. The Sun is about 4.6 billion years old, while Earth's age is estimated to be around 4.5 billion years.
Though establishing with certainty how al... |

The most widely-accepted theory over how the Moon formed suggests that it emerged from the debris field caused by a massive impact between Earth and Theia, a Mars-sized planet that existed in the early solar system. However, new data appear to indicate that this was not the case.
Under the old explanation, at least... |

A paper published in the February 16 issue of the top journal Science suggests that some of the rocks on our planet were extremely slow to change and undergo recycling. These data are now added to a growing body of gaps in our knowledge of how early Earth evolved. According to the investigation, some of the most slug... |

Reports from the Fukushima Medical University (FMU), some 60 kilometers (37.2 miles) away from the Fukushima Daiichi nuclear power plant, show what the area looks like now, months after the March 11 earthquake and tsunami that led to the meltdown of four nuclear reactors at the installation.
FMU physicist Tsuneo Kon... |

According to the conclusions of a new scientific study, it would appear that the Moon is younger than researchers first calculated. It's either that, or it evolved in different patterns over the past few billion years. It may even be that it collided with another Moon.The widely-accepted hypothesis at this point... |

New studies appear to suggest that either all or part of our planet's atmosphere did not originate within the Earth – as studies suggest – but was rather brought here by space impactors such as comets and asteroids. A new research proposes a little tweak to these ideas. University of Manchester inves... |

According to the conclusions of two new scientific studies, it would appear that the material which makes up Mercury, Venus, Earth and Mars did not originate in the protoplanetary disk around the Sun. When the star formed, not all of the gas clouds that collapsed to ignite it made it into the star. The leftover mater... |

The distant past held an entirely different continental configuration than the modern world does, experts say, and, as part of that setup, it could be that the eastern parts of Antarctica were connected to the southwestern portions of the United States. It's no secret that the world's land masses were hundr... |

A group of investigators suggests that what other researchers construed as sings of ancient Martian life in a meteorite that arrived to Earth from the Red Planet may in fact be explained through basic chemistry. This is only the last argument to be brought in a debate raging on for years.In addition, the team says, t... |

A team of astronomers has recently determined that the solar system may in fact be 2 million years older than initially estimates. In geological terms, this period of time is just the blink of an eye, but the refinement of previous calculations is bound to give experts a better understanding of how the solar system a... |

Experts recently discovered what may very well be a remnant of a primitive Earth mantle. The reservoir was identified in the Canadian Arctic, on the Baffin Island. The team that made the finding was led by geologist Matthew Jackson, who is based at the Boston University. Details of the discovery were published this w... |

For many years, experts believed that the Earth and the Moon formed some 4.537 million years ago. This is the equivalent of 30 million years after the creation of the early solar system. But new data comes to shed doubts on this conclusion, instead proposing that the planet and its natural satellite in fact formed as... |

Astronomers and astrophysicists have for a long time known that the Moon is home to a particular type of nitrogen. The isotopes that can be found in the lunar soils and dust have little in common with the chemical that makes up a vast portion of Earth's atmosphere, or to the element that can be found in other lo... |

In a new scientific study, sponsored by the US National Science Foundation (NSF), researchers have determined that at least some of the key chemical elements that allow for life to exist on our planet were included in the early building blocks of Earth. The scientists say that the planet began forming about 4.568 bil... |

Oxygen-isotope readings have for many years been used as the main source of information regarding the speed with which the Andes Mountains of South America rose. Many experts still believe that the mountain range rose quickly from the surrounding land, due to cataclysmic events caused by the tectonic plates nearby. B... |

Molybdenum-99 is one of the most crucial isotopes in the entire world, as it has numerous applications in medicine and imaging. The bad news is that next week, one of the primary reactors that regularly produce the stuff will be shut down for repairs. To make matters worst, there will be a few days in March when none... |

Researchers in Germany were recently able to use a special trap so as to collect direct measurements on the weight of no less than three isotopes of the super-heavy chemical element nobelium. While the heaviest stable element to appear in nature is uranium, science was able to synthesize as many as 25 additional chem... |

Scientists from the University of Arkansas (UA) have recently released a new report, claiming that the entire planet might have been formed out of meteoritic materials.

One of the basic facts of life is clearly the knowledge that life on our planet cannot survive without oxygen. When the Earth first formed, there was a very small concentration of the gas, maybe less than one percent of the total atmosphere. However, two big oxidation events were recorded over the eons, both of which... |

Scientists who are currently investigating if a supernova exploded inside our solar system at one point in its existence need only to find traces of a certain isotope of hafnium in order to prove their claims are genuine. These isotopes only occur after massive supernova explosions, although hafnium is fairly easy to... |

It has been widely agreed upon that oceans act as the largest carbon sinks of the world, engulfing vast amounts of carbon dioxide each year. The water in itself does not draw in carbon dioxide (CO2) – the main greenhouse gas that causes global warming. Rather, tiny organisms known collectively as the phytoplank... |

In a mind-boggling piece of engineering achievement, experts at the University of California in Davis (UCD) used a supercomputer to model the early stages of the Earth's crust, back in the days when the planet was just solidifying from an incandescent ball of red-hot lava. The goal of the simulation was to under... |
