NASA Astronomy Picture of the Day 2016 October 27 

A Giant Squid in the Flying Bat 

 Very faint but also very large on planet Earth’s sky, a giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula, are both caught in this cosmic scene toward the royal constellation Cepheus. Composed with almost 17 hours of narrowband image data, the telescopic field of view is 4 degrees or 8 Full Moons across.

Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula’s alluring bipolar shape is distinguished here by the telltale blue-green emission from doubly ionized oxygen atoms. Though apparently completely surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, a recent investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, Ou4 would represent a spectacular outflow driven by HR8119, a triple system of hot, massive stars seen near the center of the nebula. The truly giant Squid Nebula would physically be nearly 50 light-years across.

In Daylight on the Night Side

NASA’s Cassini spacecraft looks down at the rings of Saturn from above the planet’s nightside. The darkened globe of Saturn is seen here at lower right, along with the shadow it casts across the rings. 

The image shows that even on the planet’s night side, the rings remain in sunlight, apart from the portion that lies within Saturn’s shadow. The rings also reflect sunlight back onto the night side of the planet, making it appear brighter than it would otherwise appear. 

Saturn’s small moon Prometheus (53 miles or 86 kilometers across) is faintly visible as a speck near upper left. The shadow of Saturn was once long enough to stretch to the orbit of Prometheus. But as northern summer solstice approaches, Saturn’s shadow no longer reaches that far. So Prometheus will not move into the darkness of the planet’s shadow until the march of the seasons again causes the shadow to lengthen.

Consciousness VS Awareness: What’s The Big Difference?

What is the difference between awareness and consciousness? How are the two concepts interlinked? Keep reading to find out about the hidden secrets of the universe!

Imagine yourself in the middle of a forest, being chased by a bear. The rustling of leaves behind you burgeons your pace, causing a much needed adrenaline rush. As you run across the landscape, you search for possible escapes. You are aware of the trees, and the animal life in your vicinity (imagine the forest sounds), but you’re conscious about a possible, untimely end to the journey of your life.
