Green light for views of Mars, the red planet

At 21:00 on Wednesday, 14 October, the Anton Pannekoek Institute for Astronomy (University of Amsterdam) is organising a virtual viewing evening of the opposition of Mars. On that evening, the red planet will be exactly opposite the sun as viewed from the Earth. The planet will also be high in the night sky. The next such perfect opportunity to observe it will not happen for another thirty years.
