    /sigh what a most beautiful planet, isn’t she just breathtaking to look at? no wonder she is popular. The Miss universe of the planets

    What is the date these were taken? Clearly not 22 April 2013. Seems to me the post should have included this reference.

    I hope you will add it.

    They weren’t “taken” at all–they’re composite images from multiple datasets. A variant of the Black Marble series.

    I love Earth Observatory, and especially its images!

    I wish I had these when I was doing my astronomy merit badge for the scouts.

    I was and still am captivated by the world beyond our atmosphere! The striking contrast between verdant regions and arid regions shows a marked contrast. Thanks for publishing these.

    Much appreciated.
