Kanaler på Mars
Karta över Mars av Giovanni Schiaparelli.
Kanaler på Mars trodde många forskare existerade, under sent 1800-tal-tidigt 1900-tal. 1877 tyckte sig italienska astronomen Giovanni Schiaparelli se linjer på Mars, som han kallade kanaler. Spekulationer om liv tog fart, och temat blev vanligt i science fiction-berättelser. När teleskopen förbättrades i början av 1900-talet förklarades det hela vara en optisk synvilla, och myten om kanalernas existens avlivades definitivt under 1960- och 70-talens när planeten besöktes av rymdsonder.[1]

Mars Hubble.jpg
NASA's Hubble Space Telescope took the picture of Mars on June 26, 2001, when Mars was approximately 68 million kilometers (43 million miles) from Earth — the closest Mars has ever been to Earth since 1988. Hubble can see details as small as 16 kilometers (10 miles) across. The colors have been carefully balanced to give a realistic view of Mars' hues as they might appear through a telescope. Especially striking is the large amount of seasonal dust storm activity seen in this image. One large storm system is churning high above the northern polar cap (top of image), and a smaller dust storm cloud can be seen nearby. Another large dust storm is spilling out of the giant Hellas impact basin in the Southern Hemisphere (lower right).
