V-rule model. The V-rule is one of the most important ways of determining quickly the dip of planar features, i.e. the map pattern of a planar surface (e.g. fault or bedding) 'V's in the direc...

Auch schön: Aurora in rot
 
Red Aurora Over Australia
Alex Cherney (Terrastro, TWAN)
http://apod.nasa.gov/apod/ap120201.html

Why would the sky glow red? Aurora. Last week's solar storms, emanating mostly from active sunspot region 1402, showered particles on the Earth that excited oxygen atoms high in the Earth's atmosphere. As the excited element's electrons fell back to their ground state, they emitted a red glow. Were oxygen atoms lower in Earth's atmosphere excited, the glow would be predominantly green. Pictured above, this high red aurora is visible just above the horizon last week near Flinders, Victoria, Australia. The sky that night, however, also glowed with more familiar but more distant objects, including the central disk of our Milky Way Galaxy on the left, and the neighboring Large and Small Magellanic Cloud galaxies on the right. A time-lapse video highlighting auroras visible that night puts the picturesque seen in context. Why the sky did not also glow green remains unknown.

Moving books
Netzpiloten originally shared:
 
Schlaflose Bücher, die am Abend ein Eigenleben führen und einen eigenen kleinen Lesezirkel zelebrieren. Könnt Ihr euch das vorstellen? Nach dem coolen Stop-Motion-Video vom Buchhändler Sean Ohlenkamp aus Toronto vielleicht. Lustige Idee die beim umräumen der Bücherregale entstanden sein soll.

Have a look on Mars.
 
Flowing Barchan Sand Dunes on Mars

When does Mars act like a liquid? Although liquids freeze and evaporate quickly into the thin atmosphere of Mars, persistent winds may make large sand dunes appear to flow and even drip like a liquid. Visible on the above image right are two flat top mesas in southern Mars when the season was changing from Spring to Summer. A light dome topped hill is also visible on the far left of the image. As winds blow from right to left, flowing sand on and around the hills leaves picturesque streaks. The dark arc-shaped droplets of fine sand are called barchans, and are the interplanetary cousins of similar Earth-based sand forms. Barchans can move intact a downwind and can even appear to pass through each other. When seasons change, winds on Mars can kick up dust and are monitored to see if they escalate into another of Mars' famous planet-scale sand storms.

January Aurora Over Norway
Image Credit & Copyright: Bjørn Jørgensen

What's that in the sky? An aurora. A large coronal mass ejection occurred on our Sun five days ago, throwing a cloud of fast moving electrons, protons, and ions toward the Earth. Although most of this cloud passed above the Earth, some of it impacted our Earth's magnetosphere and resulted in spectacular auroras being seen at high northern latitudes. Pictured above is a particularly photogenic auroral corona captured last night above Grotfjord, Norway. To some, this shimmering green glow of recombining atmospheric oxygen might appear as a large eagle, but feel free to share what it looks like to you. This round of solar activity is not yet over -- a new and even more powerful solar flare occurred yesterday that might provide more amazing aurora as soon as tonight.

Auf der Suche nach ein paar Bildern stellte ich fest, dass ich wohl eine Vorliebe für Nahaufnahmen habe.
Besonders Flächen scheinen es mir angetan zu haben.
