DOUBLE FLYBY: On Sept. 7th, a newly discovered asteroid about the size
of a large grey whale flew over the south pole of Earth only 25,000
miles away. For scale, that's only a few thousand miles above the
orbits of typical geosynchronous satellites. After the Earth flyby, the
space rock turned and headed in the general direction of the Moon,
executing a wider flyby of 179,000 miles on Sept. 8th. Where will this
asteroid go next? Visit http://spaceweather.com for answers and photos of today's encounter with Earth.
AURORAS: A broad solar wind stream hit Earth on Sept. 1st, sparking a
display of bright auroras around the Arctic Circle that is only now
fully subsiding. Did you miss it? Browse our Aurora Photo Gallery for highlights.
