A significant number of the 22,000 pieces of large space junk the US Department of Defense keeps track of could be forced to reenter Earth's atmosphere faster than currently possible, in the event of a large solar storm. The conclusion belongs to a new study conducted by investigators with the NASA Orbital Debr... |

As evidenced decades ago, Earth is surrounded by a couple of radiation belts, atmospheric structures that contain large amounts of dangerous charged electrons. Some experts suggested that increased solar activity might be capable of driving them towards the surface, but new data shows that to be false.
Researchers d... |

During a new scientific study of the Tarantula Nebula, astronomers using the NASA Spitzer Space Telescope were able to discover vast volumes of radiations and powerful stellar winds inside the cosmic structure.
The findings again indicate that the stellar nursery is extremely active, producing young stars at a frant... |

The innermost planet in our solar system is being subjected to a constant beating at all times. Intense solar winds, which are undiluted due to the close proximity between the two bodies, literally sandblast Mercury's poles, triggering phenomena similar to the ones that generate auroras on Earth.
The new con... |

Solar physicists proposed the existence of powerful magnetic plasma waves called Alfvén waves many years ago, but thus far evidence to prove they actually form have been scarce at best. A new study now identifies the formations with a great deal of accuracy. The work represents the first time that the powerful... |

Studies conducted using a NASA orbiter are showing that the radio waves emanating from both the north and south pole on Saturn are different in their variations. Researchers say that these variations also change with seasons, and that the wave characteristics were even exchanged between the poles. At one point in tim... |

One of the most interesting conundrums in astronomy is related to why stars don't fly apart at high speeds while they form. Theoretically, when they first condense from molecular hydrogen, they should be spinning out of control, and yet they don't. A new study analyzes the potential explanations. Experts ha... |

A group of investigators proposes that the craters located at the lunar poles may be charged to hundred of volts, due to the effects of solar winds flowing above. The streams of charged particles slam into the natural obstructions produced by the edges of craters, triggering the phenomenon.The new calculations were p... |

In recent times, the international scientific community has been trapped in a debate seeking to establish whether the magnetic fields surrounding Earth are indeed responsible for our planet's appearance. One of the reasons why these discussions started is that Mars and Venus are bone dry planets. Though we are l... |

New discoveries hint at the fact that comets have far less carbon on their surfaces and at their cores than initially suspected. Experts say that this knowledge may force a rethinking of the role they attribute to these space bodies in the emergence and subsequent development and evolution of life on Earth.For years,... |

According to a new scientific study, it would appear that solar winds in fact contain significantly higher amounts of oxygen within than anyone believed was possible. The research was recently published in a top scientific journal. Though astronomers have known for quite some time that the Sun is rich in oxygen suppl... |

NASA announced recently that it has reassigned two of its five THEMIS satellites in Earth's orbit to a new mission, called ARTEMIS. The main goal of the new research initiative is to determin how solar wind electrifies, alters and erodes the lunar surface.When completed, the Time History of Events and Macroscale... |

A new scientific investigation has demonstrated the existence of a previously-unseen type of solar wind interaction, that occurs only around celestial bodies in our solar system that feature no air in their atmospheres. The interaction was clearly observed in the case of Earth's natural satellite. It takes place... |

A collaboration of research institutes and private companies in the United States recently managed to gain new knowledge into how our planet's magnetosphere protects us from solar winds. As the Sun explodes, turns and churns, it emits jets of highly-energetic particles known as the solar wind towards our planet ... |

The Solar Dynamics Observatory (SDO) is the first component of the American space agency's Living With a Star Program. The goal of this initiative is to produce viable, high-accuracy data of the reasons that underlie the formation of magnetic solar storms. Various manifestations of the Sun, including solar winds... |

About three years ago, astronomers, astrophysicists and skywatchers had the opportunity to behold one of the most spectacular comets to have entered the inner solar system for many years. Called C/2006 P1 McNaught, the celestial body left an impressive mark in the sky, with a tail extending a considerable portion of ... |

According to a new scientific investigation, it would appear that influences from the Sun are directly responsible for why Mars is constantly losing some of its atmosphere to outer space. The research team, which included astrophysicists from the University of Leicester, in the United Kingdom, believes that the s... |

A group of experts has recently managed to conclude a new project, which revolved around turning data on solar winds into music, or an acoustical representation of the regular graphs, charts and numbers. The goal of this investigation is to discover information that could otherwise get lost in the crowd, and to provi... |

In a bid to gain a deeper understanding in the formation and operation of turbulent flows, physicists at the University of Warwick have made clever use of the Ulysses spacecraft, as well as of the fact that the Sun is still at its solar minimum. The result was the equivalent of a lab workbench more than 200 million m... |

The Planetary Society has again announced plans of testing a solar sail prototype, which it hopes to have built in a spacecraft, and then launched by the end of next year. The mission would essentially attempt to harness the power of solar winds for propulsion, a feat that has been advertised for a long time, but tha... |

Using scientific measurements collected by the Hinode satellite, experts at the University College London (UCL), in the United Kingdom, have recently determined that the main triggers for solar winds in our Sun must be the very strong magnetic fields. While the winds have been known as a phenomenon for a long time, t... |

According to experts at the American space agency, the concentration of cosmic-ray radiation around us has increased considerably this year, reaching its highest level in more than 50 years of observations. The level of cosmic rays has been under constant surveillance since the advent of the space age, and such a sha... |

Experts at the University of California in Los Angeles (UCLA) have recently uncovered a previously unknown mode of energy transfer in the planet's upper atmosphere, between solar winds and the Earth's magnetosphere shield. According to the team, the find may have vast implications in the field of designing ... |

Despite the fact that Venus and Earth both began with about the same amount of water when they were first formed, our planet is currently home to 100,000 times more water than there was on our neighbor. And while it's understandable that the super-heated surface of Venus cannot sustain water (with temperatures a... |

The most elusive constant related to the planet that has not been yet accurately determined is its spin rotation, as the gas giant is covered with a thick layer of clouds, which prevents most of the instruments aboard the Cassini probe to make detailed observations. Thus, most of the methods used to measure the spin ... |
