Some evening when the weather is good, go outside and look up at the sky.¡ÖÅ·µ¤¤Î¤¤¤¤Æü¤Î¾¬¤Ë²°³°¤Ë½Ð¤Æ¶õ¤ò¸«¾å¤²¤Ê¤µ¤¤¡×

That's Mars.¡Ö¤½¤ì¤¬²ÐÀ±¤Ç¤¹¡×
Mars has been called our sister planet because it is so close to us and almost the same size as Earth.¡Ö²ÐÀ±¤Ï¡¢²æ¡¹(Ãϵå)¤«¤éÈó¾ï¤Ë¶á¤¯¤½¤·¤ÆÂ礤µ¤â¤Û¤È¤ó¤ÉÃϵå¤ÈƱ¤¸¤Ê¤Î¤Ç¡¢Ãϵå¤Î»ÐËåÏÇÀ±¤È¸Æ¤Ð¤ì¤Æ¤¤¿¡×
In 1877 Schiaparelli (a scientist)¡¡said, "I found many lines on Mars through telescopes."¡Ö1877ǯ¡¢(¥¸¥ç¥ô¥¡¥ó¥Ë¡¦)¥¹¥¥ã¥Ñ¥ì¥ê(²Ê³Ø¼Ô)¤Ï¡¢¡ØË¾±ó¶À¤òÄ̤·¤Æ¡¢²ÐÀ±¾å¤Ë¿¤¯¤ÎÀþ¤òȯ¸«¤·¤¿¡Ù¤È¸À¤Ã¤¿¡×
