The Day After Mars Image Credit & [3]Copyright: Rolando Ligustri ([4]CARA Project, [5]CAST) Explanation: October 31, 1938 was the day after Martians encountered planet Earth, and everything was calm. Reports of the invasion were revealed to be part of a Halloween radio drama, the now famous broadcast based on H.G. Wells' scifi novel [6]War of the Worlds. On Mars October 20, 2014 was calm too, the day after its close encounter with [7]Comet Siding Spring (C/2013 A1). Not a hoax, this comet really did come within 86,700 miles or so of Mars, about 1/3 the Earth-Moon distance. [8]Earth's spacecraft and rovers in Mars orbit and on the surface reported no ill effects though, and had a ringside seat as a visitor from the [9]outer solar system passed by. Spanning over 2 degrees against stars of the constellation Ophiuchus, [10]this colorful telescopic snapshot captures our view of Mars on the day after. Bluish star [11]51 Ophiuchi is at the upper right and the comet is just emerging from the Red Planet's bright glare.
