Space and the Universe
|Group leader:||Colin Brown|
|Meeting Venue:||Members' homes|
|Time:||4th Tuesday of the month at 2:30pm|
New members are welcome. If you would like to know more about our solar system and the wider universe, are interested in the technology of spaceflight, or are intrigued by the occasional space stories that appear in the news, come along to one of our meetings and see whether you would like to join us. Don't be afraid of appearing ignorant. In the face of such a huge and rapidly evolving subject we all feel ignorant, but we're there to learn.
Next meeting: We are currently taking a summer holiday, and expect to start again in October.

A simulation of Earth's 2019 encounter with the Taurid meteor swarm. They have been blamed for the 1908 Tunguska impact, the most powerful in recorded history. There is an encounter in July and August every year, but this year Earth will be at its closest for 45 years to the swarm's centre. Scientists are hoping to seize this opportunity to study them with modern telescopes, aiming to detect dangerously sized bodies and refine our understanding of any risks they pose to Earth.
