Recent observations conducted using the NASA Chandra X-ray Space Telescope revealed that energetic radiations emanating from Jupiter's northern hemisphere are in fact originating in a single hot spot. In other words, they are not produced over a larger surface area, as originally thought. What's more, the ... |

A new investigation conducted with the NASA Cassini orbiter revealed the existence of molecular oxygen in the atmosphere surrounding the Saturnine moon Dione. This chemical is absolutely essential for making air on Earth breathable, and able to support complex life.
The spacecraft did not identify quantities large ... |

In a series of previous studies, researchers proposed the existence of an atmosphere layer containing cold, electrically-charged particles, way above the planetary surface. The latest investigation into this issue reveals that to be true, as scientists discover cold plasma layer at the top of the atmosphere.
Theore... |

Using the latest data collected by the NASA Cassini orbiter, astronomers were able to determine that the moon Enceladus plays an important role in the creation of auroras on its home planet, Saturn. Investigators learned that the moon releases massive plumes of electrically-charged particles, and that these surges fl... |

There are numerous issues to consider when dealing with space exploration, not the least of which is the fact that discovering signs of life on a distant planet or moon is extremely difficult. Discovering fossils is hard enough even on Earth, let alone on space rocks such as Mars. Nevertheless, future rovers will nee... |

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 ... |

When the Large Hadron Collider (LHC) was reopened, not two months ago, the high-energy physics community was excited that the largest scientific experiment on the planet was operational. Then came the milestone that everyone wanted to see, namely the fact that the machine became the most powerful particle accelerator... |

All biology manuals in all countries around the world say that fish species developed gills in order to breathe. Teachers tell their students that the structures help facilitate the transfer of oxygen from the water into the marine creatures, thus basically allowing them to breathe under water. But, now, a new resear... |

Astronomers using the Japan-US Suzaku telescope have recently discovered fossilized traces in two supernova remnants, which bear witness to the tremendous fireballs that formed at the two locations just after the stars that went supernova exploded. When such a cosmic event occurs, experts believe that the temperature... |

Engineers working on rocket propulsion systems realized a few decades ago that chemical reactions would at one point reach a stage in which advancement would do little to increase a delivery system's overall thrust. They began working on new system, which they believed could one day successfully replace oxygen- ... |

In an interesting, new development, scientists have demonstrated for the first time that strontium ions congregate on the surface of water. The behavior of this type of ions, which are, in fact, divalent cations (two electrons missing), has been a subject for scientific debate until now, because theoretical models an... |

Even in the cleanest of cleanrooms, fine particles can deposit themselves on intricate circuit boards. Although it may not seem like much, they have the ability to severely alter the operating parameters of a certain instrument, tainting the results obtained with it, and generally making scientists' lives misera... |

In a groundbreaking, new research, experts at Japan’s National Institute of Advanced Industrial Science and Technology (AIST) have developed a new type of batteries, containing nickel and lithium, which can hold 3.5 times more energy than the average lithium-ion battery and is also much safer to boot. That is t... |

While advocates of healthy eating look for options of substituting sodium in salt, nuclear physicists working on making nuclear fusion a reality are also looking for substitutes of their own. They have thus far discovered that sodium-like tungsten ions could successfully replace the troublesome element, and that they... |

Cosmic radiations permeate everything around us at all times of the day. Some of them are generated near us, on a radius of a few thousand light-years, while some only reach our planet after a ten- to 11-billion-year journey. They are unnoticeable to humans, but some researchers believe they may have played a crucial... |

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... |

Creating junctions inside future quantum processors is a very important step in their design. Actually, some may argue that this is the most important step, as, without a pathway to carry information from one place to the other inside a processor, all other innovations in the area are useless. However, the main probl... |

Plasma has two main components, the positive and the negative clouds of gas mixed in different proportions. Neutral plasma containing equal amounts of positive and negative charges is called strongly-coupled plasma and occurs naturally on the surface of neutron stars, the cores of gas giants and may have even been th... |

Because plasma is mostly composed of charged particles, such as electrons and ions, which have a global neutral charge, it is able to generate powerful magnetic fields, a very important feature if you ask a nuclear physicist working on the design of a nuclear fusion reactor. However, all good things must also have ba... |

The ion engine is the best electric propulsion system available for spacecraft so far. It's the engine which can produce the best electric power to thrust conversion rate. It also has the highest specific impulse, of about 3000secs (around 30,000 km/s or 18,600 mph) and the longest operational lifetime. It surp... |
