The Draconids are coming! Will this meteor shower produce a storm of observable meteors, or just a minor squall? The Draconid Meteor Show should begin on October 8, 2011 starting at dusk (roughly 19:00 BST) and continue through the evening. Peak activity of this normally minor and quiet shower is estimated to be at 21:00 BST (20:00 UT). There seems to be a wide range of predictions for this year’s shower, but some astronomers believe there could be up to 1,000 meteors per hour, making this a meteor storm! (more…)
If you ask someone to describe or draw a telescope, nine times out of ten it will be a refractor.
The refractor telescope is quite possibly the most common or easily recognized telescope. It is a very simple design, which has been around for hundreds of years.
The history of the refractor is that it was first invented in the Netherlands in 1608, and is credited to 3 individuals; Hans Lippershey, Zacharias Janssen – spectacle-makers and Jacob Metius. (more…)
Reusability is key to the dramatic cost savings that will enable advancements in human exploration of space. The Dragon spacecraft is a fully reusable and SpaceX is working toward the goal of delivering the world’s first fully reusable launch vehicle. Check out the animation for a sneak peek at SpaceX’s exciting plans for the future.

A highly active region on the Sun threatens to deliver powerful geomagnetic storms over the week ahead. Highly energetic solar eruptions are likely heading in our direction to give Earth’s magnetic field a significant glancing blow!
Over the past few days the new sunspot AR1302 has been incredibly active, hurling massive X-class solar flares into space and it will soon face Earth.
The massive sunspot, many times larger than the Earth (see images below) is expected to increase in size and energy, and is expected to release powerful solar flares, sparking strong geomagnetic storms. (more…)
A severe geomagnetic storm (Kp=7-8) that began yesterday when a CME hit Earth’s magnetic field is subsiding. At the peak of the disturbance, auroras were sighted around both poles and in more than five US states and Northern Europe.

Sky watchers at the highest latitudes should remain alert for auroras as Earth’s magnetic field continues to reverberate from the CME impact.
More solar activity is expected, so stay posted for more Aurora news.
