Solar eruption ‘photobombed’ Mars encounter with Comet Siding Spring

When Comet C/2013 A1 (Siding Spring) passed just 140,000 kilometers from Mars on 19th October 2014, depositing a large amount of debris in the Martian atmosphere, space agencies coordinated multiple spacecraft to witness the largest meteor shower in recorded history. It was a rare opportunity, as this kind of planetary event occurs only once every 100,000 years.

Solar wind impacts on giant 'space hurricanes' may affect satellite safety

Could the flapping of a butterfly’s wings in Costa Rica set off a hurricane in California? For most people, this hypothetical scenario may be difficult to imagine on Earth — particularly when a real disaster strikes. Yet, in space, similarly small fluctuations in the solar wind as it streams toward the Earth’s magnetic shield actually can affect the speed and strength of ‘space hurricanes,’ a researcher explains.
