Look What You’ve Done. I’m Molting…MOLTING!!!
Adult female Cicadas lay eggs inside the bark of trees by means of an ovipositor. When the eggs hatch, the newly hatched nymphs drop to the ground and burrow.
Cicadas live underground as nymphs for most of their lives at depths down to about 2.5 metres (8 ft). Nymphs have strong front legs for digging and excavating chambers in close proximity to roots where they feed on xylem sap. In the process, their bodies and interior of the burrow become coated in anal fluids. In wet habitats, larger species construct mud towers above ground in order to aerate their burrows.
In the final nymphal instar, they construct an exit tunnel to the surface and emerge. They then molt (shed their skins) on a nearby plant for the last time, and emerge as adults. The exuviae or abandoned exoskeletons remain, still clinging to the bark of the tree.
Most cicadas go through a life cycle that lasts from two to five years. Some species have much longer life cycles, such as the North American genus, Magicicada, which has a number of distinct “broods” that go through either a 17-year or, in some parts of the world, a 13-year life cycle.
These long life cycles may have developed as a response to predators, such as the cicada killer wasp and praying mantis. A specialist predator with a shorter life cycle of at least two years could not reliably prey upon the cicadas.
Video Clip SS276149 (Tesla Coil Arching With Man’s Tongue)
Footage of an electrical discharge, produced from a Tesla coil, arching towards a man’s tongue.
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. It is used to produce high-voltage, low-current, high frequency alternating-current electricity.

He used these coils to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires.
Today their main use is for entertainment and educational displays, although small coils are still used today as leak detectors for high vacuum systems.

Video Clip SS220029 (Zoom Into Hubble Ultra Deep Field)
In 2003, Hubble Stared Into A Tiny Patch Of Darkness…
The original HUDF image was taken in 2004, in a tiny patch of the sky in the constellation Fornax. In 2009 the same area was imaged with the new Wide Field Camera 3, in near-infrared wavelengths.
The Hubble Ultra Deep Field (HUDF) image contains as many as 10,000 galaxies of all shapes, sizes, colors, & ages. Taking it required 800 exposures taken over the course of 400 orbits around Earth.
In ground-based photographs, the patch of sky where Hubble was pointed, just one-tenth the diameter of the full Moon, is largely empty. Located in the constellation Fornax, this region is so empty that only a handful of stars within the Milky Way galaxy can be seen.
The image was the deepest view of the universe at the time, looking back to galaxies formed as little as 600 million years after the Big Bang. In staring at this video, you are literally staring back through time.

Video Clip SS235282 (Night Sky Over the Paranal Observatory)
Timelapse of the night sky over the Paranal Observatory, Cerro Paranal, Chile.
A bright meteor streaks at dusk and satellites and planes cross the sky. The southern Milky Way and bright stars Alpha and Beta Centauri appear in the sky as well as the Omega Centauri star cluster on the left.

By total light-collecting area, the Paranal is the largest optical-infrared observatory in the Southern Hemisphere. Worldwide, it is second only to the Mauna Kea Observatory on Hawaii.
In the foreground is one of the 1.8 metre axillary telescopes of the Very Large Telescope (VLT) interferometer program. The VLT is located at an altitude of 2600 metres in the Atacama Desert.
The Very Large Telescope (VLT) is the largest telescope on Paranal. It is composed of four separate 8.2 m (320 in) telescopes. In addition, the four main telescopes can combine their light to make a fifth instrument, the Very Large Telescope Interferometer (VLTI).

Video Clip SS249656 (Surface Tension Of Water)
Surface tension of water as revealed by a paperclip.
The paperclip has been placed over a surface marked with parallel lines. The water in contact with the paperclip forms a meniscus, as the water molecules are attracted to the molecules of the metal clip. This makes the water around the paperclip slightly thicker, which refracts the light passing through it, distorting the appearance of the parallel lines.
See More Example of Surface Tension
The cohesive forces between molecules in a liquid are shared with all neighboring molecules. Those on the surface have no neighboring molecules above and, thus, exhibit stronger attractive forces upon their nearest neighbors on and below the surface.
Water molecules want to cling to each other. At the surface, however, there are fewer water molecules to cling to since there is only air above. This results in a stronger bond between those molecules that actually do come in contact with one another, and a layer of strongly bonded water.
This surface layer (held together by surface tension) creates a considerable barrier between the atmosphere and the water. In fact, other than mercury, water has the greatest surface tension of any liquid. -USGS-

Alexander von Humboldt - The Man Who Predicted Climate Change
One man first recognized man-made Climate Change, inspired Charles Darwin’s journey into the Galapagos and revolutionized the concept of nature while braving the wilds of 19th century Central & South America.
Alexander von Humboldt set off to survey the new world, scaling volcanoes, exploring jungles and changing scientific thought. His radical theory that nature was a complex and interconnected global force, and not merely a tool for human civilization, laid the foundation of environmentalism.
Video Clip SS270763 (Kelvin-Helmholtz Wave Clouds, Timelapse)
Time-lapse footage of strong wind shears curling high-altitude clouds into a distinctive and ephemeral Kelvin-Helmholtz wave pattern.
This distinct corkscrew pattern is formed by layers of air moving across each other in opposite directions, creating a series of circular air movements in between them.
This type of cloud generally forms at high altitude and dissipates rapidly. The formation seen here is associated with a jet stream in the lee of the Rocky Mountains.
Filmed on a winter’s afternoon in Colorado, USA.

Video Clip SS241672 (Dendritic Ice Crystal Growth)
Macro timelapse footage of Dendritic Ice Crystals Growing.
At sub zero temperatures, moisture from the surrounding atmosphere condenses almost immediately. The dendritic (tree-like) form of the crystallization is a natural fractal pattern.
As a rule, except in conditions where supercooled droplets are present in the air, frost will form only if the deposition surface is colder than the surrounding air. For instance frost may be observed around cracks in cold wooden sidewalks when humid air escapes from the warmer ground beneath. Other objects on which frost commonly forms are those with low specific heat or high thermal emissivity, such as blackened metals; hence the accumulation of frost on the heads of rusty nails.

8 Years Of Staring Directly At The Sun
The Solar Dynamics Observatory was the first mission to be launched for NASA’s Living With a Star (LWS) Program, a program designed to understand the causes of solar variability and its impacts on Earth.
SDO is designed to help us understand the Sun’s influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.

SDO’s goal is to understand, driving towards a predictive capability, the solar variations that influence life on Earth and humanity’s technological systems by determining
The Solar Dynamics Observatory celebrated its 8th anniversary since it launched on February 11, 2010. This time-lapse video captures one frame every 8 hours starting when data became available in June 2010 and finishing February 8, 2015.
The different colors represent the various wavelengths (sometimes blended, sometimes alone) in which SDO observes the sun.

Video Clip SS272144 (Phases of the Far Side of the Moon)
Animation showing a time-lapse wide-angle view of the phases of the far side of the Moon, with the Earth rotating behind it.
The Earth rotates on its own axis in 24 hours. The Moon orbits the spinning Earth in approximately 27.3 days, but because the Moon rotates upon its own axis once during the same period, it always presents the same side to the Earth.

As the Moon orbits the Earth, the area of its surface lit by the Sun changes, resulting in the lunar phases. The animation was created using data from NASA’s Lunar Reconnaissance Orbiter.
