The Carina Nebula (NGC 3372) is one of the largest and brightest such formations in the sky, and also one of the most complex and intricate, as far as internal structures go. The 100 light-years-long formation is approximately 4 times larger than the Orion nebula, and is located in the Constellation bearing the same ... |

The memorable event that takes place on the Earth's poles, called aurora, is not only restricted to our planet. The Sun and the magnetic fields of other planets allow for it to occur in the different atmospheres of the latter as well, although it may look nothing like what we're accustomed to. In fact, they... |

The Cassini probe found in Saturn's orbit has managed to depict yet another mystery of the ringed planet. The content of the most recent images that the spacecraft sent back to the Earth have startled experts again. The photographs unveiled a mysterious phenomenon occurring at the planet's northernmost lati... |

The dynamics of explosive magnetic substorms, responsible for generating the aurora borealis and for the interferences affecting both satellites in Earth's orbit and electric and electronic devices on the surface, have now been revealed by NASA's five THEMIS spacecrafts, solving a mystery that has been a ce... |

Voyager 1 and Voyager 2 are two of the most important spacecrafts in the history of space and solar system exploration, and currently the only two man-made objects to go beyond the limits of the solar system. Voyager 1 crossed the termination shock, the area of space where solar wind and interstellar radiation collid... |

The Van Allen radiation belt consists of two concentric zones inside of which charged subatomic particles are being trapped by Earth's geomagnetic field. The outer belt is able to capture particles from the solar wind and retain them for as long as a week, while the inner belt could keep particles trapped inside... |

Well, sending a probe into the Sun wouldn't do much good would it, considering that the spacecraft will be totally destroyed by the dreaded heat radiating from the star? However, the Solar Probe will be the closest spacecraft ever sent to the Sun and its orbit will eventually pass through the star's outer a... |

After a mission of twelve years to study the Aurora Borealis phenomenon the Polar satellite has now produced its final image, "The Broken Heart", as NASA researchers named it, a visible-light photograph of the lights generated during the interactions between solar wind, Earth's magnetic field and the upper atmos... |

Earth's powerful magnetic field is shaped by the solar wind into a tear-like elongated structure, enveloping the planet. This so called magnetotail spans well beyond the orbit of the Moon, meaning that the Moon passes through it once a month, during the full moon phase, determining lunar dust storms and electros... |

Traditional propulsion systems are highly inefficient when it comes to space travel, mostly because they have to carry fuel on board, thus after covering a fair amount of distance, spacecrafts often find themselves drifting helplessly through the immensity of space. The effect can be clearly observed even with satell... |

NASA plans to send a manned mission to the Moon by 2020, but in order to do that it must once again learn what the Moon is like. "Humans will return to the Moon in a few years and have to know what to expect. How do you live and work in a place filled with moondust? We're trying to find out," said James Spann fr... |

The solar wind originates from the Sun of course, everybody knows that, but not many can explain how solar wind is actually generated, at least not in an accurate manner. Yesterday, a team of researchers from the University College London's Mullard Space Science Laboratory, led by professor Loise Harra, presente... |

The newly discovered glowing feature in Jupiter's atmosphere seems to be produced by a stream of electrically charged particles rushing from the planet's small volcanic moon Io, much in the same way the solar wind determines the appearance of aurora borealis on Earth in the polar region of the planet. Accor... |

Have you ever noticed how both Mars and Venus are ranked as planets rather similar to Earth, but never to each other? The ESA believes it's about time it put an end to this situation and gave the task to both the Mars Express and the Venus Express, to conduct simultaneous probing investigations to establish whet... |

What better evidence for the coming of spring than the appearance of the aurora borealis, or most commonly known as the northern lights? Well, at least astrologically speaking, in the context of ever wobbling clime. For some unknown reason, it seems that the aurora borealis phenomenon takes place only during the spri... |

Following the steps of their fellow colleagues form the European Space Agency, NASA also has in plan to implement a program to predict the space weather determined by the activity of the closest star to Earth - the Sun. Lying just over 150 million kilometer from Earth, the Sun, with a diameter about 100 times that of... |

It has been long predicted that solar wind interactions would be able to generate massive amounts of X-ray radiation, however until now astronomers haven't been able to detect such emissions. Now, they have revealed what seems to be a large X-ray emission coming from the Eta Carinae binary system, determined by ... |

New observations on one of the most mysterious planets in the solar system suggest that Mercury has a comet-like tail. However, while the cometary tails are relatively bright and often visible with the naked eye from the surface of the Earth, Mercury's tail is less visible in the visible spectrum. Previous obser... |

Our planet's magnetic field is strong enough to protect the surface from deadly radiation coming from the Sun, and, without it, the Earth would probably be pretty much dead. The Earth is being daily bombarded with massive amounts of solar wind, still Mercury receives even more radiation considering the fact that... |

On December 11 last year, the SOHO spacecraft observed a small magnetic knot on the surface of the Sun. However, no visible sunspots have been detected lately, spots that are usually associated with the beginning of a new solar cycle. Although the sunspots were missing, scientists rushed to predict that the 24th sola... |

Here on Earth, life is protected relatively well from the effects of deadly radiation, due to the planet's magnetic field, which forms a protective shield against electrically charged energetic sub-atomic particles. However, though it has been more than three decades since the last man walked on the surface of t... |

The beautiful northern lights, or Aurora Borealis as they are commonly known, are usually triggered in the northern regions of the Earth, as electrically charged particles originating in the solar winds are captured by the planet's magnetic field and drawn towards the general regions of the poles. These electric... |

Taking advantage of the relative quiet solar conditions during this year's spring and summer, the STEREO B solar-orbiting spacecraft observed a succession of wavefronts of solar material passing by Earth, by using its Sun Earth Connection Coronal and Heliospheric Investigation instruments, or SECCHI for short. ... |

The solar wind represents an emission from the Sun in the form of electrically charged particles, mostly hydrogen, which fills the void space all around the star. Scientists say that these deadly waves of radiation blowing through the whole solar system at speeds as high as 1.6 million kilometers per hour are trigger... |

Scientists trying to measure Saturn's precise rotation rate have been experiencing difficulties in timing the radio pulses that the planet emits. Determining the precise rotation rate for planets with no solid surface like the gas giants has proven extremely difficult. The method they have been using consists of... |
