Astronomy Picture of the Day
\t\t\t\tDiscover the cosmos!<\/a> Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.\t\t\t
\t\t\t\t\t\t\tExplanation:<\/strong> What\u2019s causing this unusually long cloud on Mars<\/a>?\u00a0Known as the Arsia Mons Elongated Cloud<\/a> (AMEC) and first recorded by NASA\u2019s Viking Orbiter 2<\/a> in 1977, the strange cloud<\/a> has been imaged in greater detail more recently by ESA<\/a>\u2019s robotic Mars Express<\/a> spacecraft.\u00a0The featured<\/a> image<\/a> is from 2018. The cloud forms<\/a> only during spring<\/a> and summer seasons<\/a> and then only during morning hours. Made of water-ice, the most familiar process that causes cloud crystals<\/a> to form around bits of dust<\/a> would fail due to the thinness and lack of dust high in the Martian atmosphere<\/a>. Leading speculation<\/a> holds that dust is not involved. After the cloud forms near the volcano Arsia Mons<\/a>, wind blows the cloud downstream<\/a> \u2014 creating a tail that can extend over 1500 kilometers. Efforts to better understand AMEC<\/a>s will continue, an understanding that may bolster a more complete view<\/a> of cloud formation<\/a> on Earth<\/a>.<\/p>\n
