“A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time.”
— Carl Sagan

One Special Day in the Life of Planet Earth

The cameras on NASA’s Cassini spacecraft captured this rare look at Earth and its moon from Saturn orbit on July 19, 2013. Taken while performing a large wide-angle mosaic of the entire Saturn ring system, narrow-angle camera images were deliberately inserted into the sequence in order to image Earth and its moon. This is the second time that Cassini has imaged Earth from within Saturn’s shadow, and only the third time ever that our planet has been imaged from the outer solar system.

Earth is the blue point of light on the left; the moon is fainter, white, and on the right. Both are seen here through the faint, diffuse E ring of Saturn. Earth was brighter than the estimated brightness used to calculate the narrow-angle camera exposure times. Hence, information derived from the wide-angle camera images was used to process this color composite.

Both Earth and the moon have been increased in brightness for easy visibility; in addition, brightness of the Moon has been increased relative to the Earth, and the brightness of the E ring has been increased as well.

The first image of Earth captured from the outer solar system was taken by NASA’s Voyager 1 in 1990 and famously titled “Pale Blue Dot”. Sixteen years later, in 2006, Cassini imaged the Earth in the stunning and unique mosaic of Saturn called “In Saturn’s Shadow-The Pale Blue Dot”. And, seven years further along, Cassini did it again in a coordinated event that became the first time that Earth’s inhabitants knew in advance that they were being imaged from nearly a billion miles (nearly 1.5 billion kilometers) away. It was the also the first time that Cassini’s highest-resolution camera was employed so that Earth and its moon could be captured as two distinct targets.

The Equation of Time: Clocks Vs Sundials

A few centuries ago, the arbiter of “local noon” wasn’t the mechanical clock, it was the sundial. The pseudoscientific-sounding “equation of time” is how you convert between the two — and perhaps not the way you’d expect.

Hubble Photographs Turbulent Neighborhood Near Eruptive Star

A small portion of the rough-and-tumble neighborhood of swirling dust and gas near one of the most massive and eruptive stars in our galaxy is seen in this NASA/ESA Hubble Space Telescope image. This close-up view shows only a three light-year-wide portion of the entire Carina Nebula, which has a diameter of over 200 light-years. Located 8,000 light-years from Earth, the nebula can be seen in the southern sky with the naked eye.

Dramatic dark dust knots and complex structures are sculpted by the high-velocity stellar winds and high-energy radiation from the ultra-luminous variable star called Eta Carinae, or Eta Car (located outside the picture). This image shows a region in the Carina Nebula between two large clusters of some of the most massive and hottest known stars.

This is actually a test showing how sponges pump water through themselves for filter feeding!
They simply colored the water around them so you could easily see the process :D

if you don’t think that’s the coolest shit…
