There Are Many Different Ways To Make Nanomaterials But Weaving, The Oldest And Most Enduring Method

(Credits go to TaySwiftVidz)

43 years ago, on December 7, 1972, the crew of Apollo 17 snapped a shot of the nearly fully illuminated Earth on their way to the moon. It became an iconic image representing Earth’s frailty and the global activist movements of the 70s.

Since then, no human has been far enough away from Earth to capture the entire globe. But thanks to a satellite called the Deep Space Climate Observatory (DSCOVR) we can now see up to date new blue marble-esque images almost every day. 

The satellite monitors solar wind and solar magnetic storms to help scientists better forecast severe space weather events that can actually knock out power here on earth. It sits some 900,000 miles away from earth at Lagrangian Point 1, a place in space the pull of the earth and the sun balance each other out and a satellite can maintain a stable position.

On board, NASA’s Earth Polychromatic Imaging Camera (EPIC) is perpetually staring back at Earth, capturing images of our planet and beaming them home. You can see them at this website.

New video on the Hubble Sequence! Had a lot of fun making this one, enjoy!

My life in a picture

For a moment, that black and white photo should seem like a full color image. (You have to keep both the image and your head very still).

This illusion was used in the new BBC Four series Colour: The Spectrum of Science.

It demonstrates a phenomenon called “cone fatigue.” When we stare at the purple hillside in picture above, photoreceptors in our eyes called cones are stimulated. They send a signal to our brains that says “You’re looking at something purple.” But the sensing ability of those cones decreases the longer we stare at the image - those receptors are, in a way, temporarily used up.

Then when we look at the black and white image, those same cones can’t detect any purple light. Instead they sense the color that remains: green.

Tonight: A Supermoon Lunar Eclipse

Tonight a bright full Moon will fade to red. Tonight’s moon will be particularly bright because it is reaching its fully lit phase when it is relatively close to the Earth in its elliptical orbit. In fact, by some measures of size and brightness, tonight’s full Moon is designated a supermoon, although perhaps the “super” is overstated because it will be only a few percent larger and brighter than the average full Moon. However, our Moon will fade to a dim red because it will also undergo a total lunar eclipse – an episode when the Moon becomes completely engulfed in Earth’s shadow. The faint red color results from blue sunlight being more strongly scattered away by the Earth’s atmosphere. Tonight’s moon can also be called a Harvest Moon as it is the full Moon that occurs closest to the September equinox, a time signaling crop harvest in Earth’s northern hemisphere. Total eclipses of supermoons are relatively rare – the last supermoon lunar eclipse was in 1982, and the next will be in 2033. Tonight’s supermoon total eclipse will last over an hour and be best visible from eastern North America after sunset, South America in the middle of the night, and Western Europe before sunrise.

Here are ten thoughts that will change the way you think about existence.
