 The wind-sculpted sandstone column of Wadi Al Disah (Valley of the Palms) in Tabuk (Saudi Arabia).

This is actually a mushroom rock, a landform created by the action of wind erosion.

 Wolves live, hunt, raise young and spend most of their lives in packs. They're highly social animals. 

This is what happens when one of them leaves the pack for some time and then reunites with it.

 A rocket stove is an efficient and hot burning stove using small-diameter wood fuel, using an insulated vertical chimney, which ensures almost complete combustion.

Here's how to build one with snow.

 You've certainly already heard a singing wren. 

What you probably don't know is that its song is particularly pleasant to your ear, because of the striking similarities between its and human music

 Salzburger Nockerl, like Apple strudel, has become an icon of Austrian cuisine. 

Legend has it that the dessert was invented by Salome Alt, the concubine of Prince-Archbishop Wolf Dietrich Raitenau in the early XVII century.

 Swiss Alps cover around 58% of the country's area.

But the the country's landscape is actually pretty diverse with countless rivers and more than 1,500 lakes.

 Saint-Malo, in Brittany, experiences some of the highest tides in Europe, with water levels that can rise over 13 meters.

These houses are constructed as a seawall, with four layers of glass on the front-facing windows for protection.

 Yes, it can be quite noisy, especially during high tides or storms when the sea crashes against the walls and buildings. The sound of waves hitting the seawall and the wind can create a constant roar. Despite the protective design, the noise from the ocean can still be significant in such an environment. 
 Danxia, the heart of Zhangye National Geopark, is renowned for its strikingly vibrant rock formations, which are smooth, sharply defined, and rise hundreds of meters high. These unique colors and shapes formed over 24 million years from layered deposits of sandstone and various minerals.

 It's possible that the fireball could have been a fragment from a comet, but fireballs are more commonly associated with meteors or space debris. Comets are icy bodies that orbit the sun, and while they can leave trails of debris that Earth passes through, causing meteor showers, they usually don't create fireballs themselves unless a fragment of the comet breaks off and enters Earth’s atmosphere.

 Yes, the Compaq Portable III (model 2660) indeed featured an orange plasma display, which was quite distinct for its time! This display type is known as a gas-plasma display and produces an orange or amber glow, which contrasts with the more common green and white phosphor screens of that era.

The orange color was a byproduct of the plasma technology, which worked by electrically exciting gas to produce light. This type of screen was advantageous because it offered a relatively high contrast, making text and simple graphics appear clearer than on the monochrome CRTs of that time.  
 The Dakota fire pit is a straightforward yet highly effective setup. It burns from the top down, creating a steady, smooth airflow from the intake hole, which supports nearly complete combustion with minimal or no visible smoke.
