Cuprite is commonly found as an oxidation product of copper sulphides in the upper zones of veins, often associated with Native Copper, Malachite,Azurite, Limonite and Chalcocite. A fibrous form of Cuprite is known as Chalcotrichite

NIGHTJARS

You heard me.  

Nightjars.

They are the BEST birds.  Don’t come at me with BUT CORVIDS y’all know Corvids aren’t birds, they’re magic.

Anyway.  Nightjars.  Why nightjars, you might ask.  Well let me tell  you why.

I’ve already told you about the Tawny Frogmouth

image

But there is also the Great Eared Nightjar

image

Pennant-winged Nightjar

image

Standard-winged Nightjar. Yes, those are part of its wings. No, I don’t know WTF.

image

This oddly shaped stump.  haha tricked you!  It’s a Tawny frogmouth and baby.

image

Lyretail Nightjar.  again, why.  again, no idea.

image

Australian owlet-nightjar

image

Swallowtail Nightjar.  Not so fancy?  look again. that mustache.

image

Not into cute mustaches on birds?

Tell that to this Sickle-winged Nightjar.  

image

Before it cuts you down with its badass wings.

image

Hey another stump - wait no it’s a FROGMOUTH

image

I’m not the first to have come to this conclusion.  

image

says right there.  BEST BIRD.

image

Ok whatever Indian Nightjar doesn’t care what you think about it.

If you don’t agree, you can sit over there and be wrong.

"Please hold the line, your call is important to us." It's a sentence we're all frustratingly familiar with. Thankfully, mathematics can help. Queueing theory studies such situations mathematically, and tries to find solutions that minimise the average customer waiting time while also limiting the average time a queue server remains idle. This double constraint makes the problem a difficult one. An additional source of difficulty is the randomness involved. Customers usually do not arrive at regular intervals, but their arrival times are what is called a stochastic process. Coming up with a general formula that provides a solution for such stochastic problems is generally difficult, and sometimes even impossible.

A Disturbance In The F-Ring

A Disturbance In The F-Ring

A bright disruption in Saturn’s narrow F ring suggests it may have been disturbed recently. This feature was mostly likely not caused by Pandora (50 miles or 81 kilometers across) which lurks nearby, at lower right. More likely, it was created by the interaction of a small object embedded in the ring itself and material in the core of the ring. Scientists sometimes refer to these features as “jets.”

Because these bodies are small and embedded in the F ring itself, they are difficult to spot at the resolution available to NASA’s Cassini spacecraft. Instead, their handiwork reveals their presence, and scientists use the Cassini spacecraft to study these stealthy sculptors of the F ring.

This view looks toward the sunlit side of the rings from about 15 above the ring plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 8, 2016.

The view was acquired at a distance of approximately 1.4 million miles (2.2 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 105 degrees. Image scale is 8 miles (13 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado. -NASA/JPL-

Earthset From The Lunar Reconnaissance Orbiter : On The Moon, The Earth Never Rises Or Sets. If You Were

Earthset from the Lunar Reconnaissance Orbiter : On the Moon, the Earth never rises or sets. If you were to sit on the surface of the Moon, you would see the Earth just hang in the sky. This is because the Moon always keeps the same side toward the Earth. Curiously, the featured image does picture the Earth setting over a lunar edge. This was possible because the image was taken from a spacecraft orbiting the Moon - specifically the Lunar Reconnaissance Orbiter . In fact, LRO orbits the Moon so fast that, from the spacecraft, the Earth appears to set anew about every two hours. The featured image captured one such Earthset about three months ago. By contrast, from the surface of the Earth, the Moon sets about once a day with the primary cause being the rotation of the Earth. LRO was launched in 2009 and, while creating a detailed three dimensional map of the Moons surface, is also surveying the Moon for water and possible good landing spots for future astronauts. via NASA

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.
