Normally, when a comet, asteroid, or moon is discovered in our Solar System, the discoverer gets to name the object. This time around, scientists are changing things up! In early October, scientists announced the discovery of 20 new moons in orbit around the planet Saturn. The team who found these new Saturnian satellites have created a Twitter contest, whereby anyone from around the world can suggest names for them. Want to try and name a moon of Saturn? Then check out this article.

Even nearing the end, the Cassini spacecraft is still producing amazing science. This story focuses on Saturn's moon Enceladus; researchers from Cornell University in New York say they have found evidence that the moon has changed its polar axis of spin. This is based on features they've found on the surface of the moon.

The Total Solar Eclipse of 2017 that crossed the United States garnered international attention. Here in Canada we were treated to a beautiful partial solar eclipse, and the Canada Aviation and Space Museum attracted thousands of visitors to watch. Here NASA has published some of the ways the eclipse was watched, from the ground and from space. My favourite is the above picture because it has the Sun, which is 150 million kilometres away, the Moon, which is 400,000 kilometres away, and the

The Cassini spacecraft has made some truly remarkable discoveries within the Saturnian system, where it has been orbiting for the last 13 years. One such discovery is of the walnut-shaped moons: Atlas, Daphnis, and Pan. These moons sport a prominent equatorial ridge pattern circumnavigating the moons (Saturn's moon Iapetus also as an equatorial feature, though not as prominent as these). The ridges are due to where the moons are located. They are all located in or very near to the ring system

The NASA/ESA Mission to Saturn, the Cassini-Huygens spacecraft, snapped this shot of the moon Tethys, a 1000 km wide moon of Saturn. Featured in the lower right is Ithaca Chasm. This canyon is about 100 km wide and 2000 km long; it stretches nearly 75% around the moon itself.

The Earth's magnetic field is powered by an internal dynamo at the core of the planet. At the very centre of the Earth is a very hot, solid, iron core that is surrounded by an outer liquid iron region. The heat from the inner core drives convection in the outer core (hot parts of the liquid rise, cool parts fall). All the while, the core is rotating. Since the liquid outer core is a conductor, the motions of rotation and convection generates a magnetic field. The Moon has no such magnetic field
