Earth Between the Rings of Saturn

A beautiful image published by NASA, taken by the unmanned Cassini-Huygens spacecraft, shows the Earth between the rings of Saturn. The image is taken on April 12, 2017.

“Consider again that dot [Earth]. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.”

The Black Marble: Earth from Space at Night

The first new global map of Earth from space at night since 2012 has been released by the NASA scientists. The nighttime look of our planet is dubbed the “Black Marble”. But why?

On December 7, 1972, the crew of Apollo 17 spacecraft en route to the Moon took a photo of Earth from the space, at a distance about 45,000 kilometers (28,000 miles). This image, with the official NASA designation AS17-148-22727, became known as “The Blue Marble”.

In fact, it was not the first clear image of Earth taken from the space – similar photos had already been taken as early as 1967. But, the 1970s were the scene of a big surge in environmental activism. For example, on April 22, 1970, the first “Earth Day” organized by Gaylord Nelson, former senator of Wisconsin, and Denis Hayes, Harvard graduate student. Millions of people gather in the United States for the event.

Scale of the Solar System (and the first flybys of planets)

Previously I posted two articles titled “If The Moon Were Only 1 Pixel – A Tediously Accurate Map Of The Solar System“, and “A Scale Model of Solar System Drawn in the Desert and the Result is Stunning“. Since the human brain cannot deal with the really large numbers, these articles provide an amazing way to understand how big actually our Solar System is.

Now, I decided to put the Solar System into scale as an infographic. You can see a scaled Solar System below, the planets’ distances from the Sun, and the first flybys over them. Plus some statistics about the planets and our home planet, the Earth.

A Year of Earth From a Million Miles Away

A year after returning its first image, NASA’s EPIC camera, a four megapixel CCD camera and telescope attached the Deep Space Climate Observatory (DSCOVR) shows us an entire year of Earth from almost one million miles away. The result is the amazing video below.

With the voice of Jay Herman, EPIC lead scientist.
