Anyone who lives in the Midwestern region of the United States knows that thunderstorms can be an awe-inspiring (and dangerous) event. A supercell is a particular kind of thunderstorm which is characterized by the presence of a mesocyclone, a deep, rotating updraft.
Thunderstorms can be broken up into 4 different categories — supercell, squall line, multi-cell, and single-cell — and supercells are the least common of the bunch. However, they are also the most severe.
So how do Supercell Thunderstorms form?
The supercell thunderstorms rotate by tilting along the horizontal vortex, an action powered by wind shear. In addition, strong updrafts lift the tilting air to cause an additional rotation around the vertical axis, thus forming the internal mesocyclone.
Seen above are some epic photographs capturing the mesocyclone formation period. Hopefully, you get a sense of the unpredictable power of nature.
Fritz Goro was a German-born photographer known by many to be the most influential science photographer the world has ever seen. He was born in Bremen, Germany and studied at the Bauhaus school of sculpture and design. In 1933, Goro and his family fled Nazi Germany for the United States and they never looked back. For over 40 years, he captured incredibly influential science photos working for LIFE magazine and Scientific American.
Seen here is just a sample of the timeless images Mr. Goro was able to capture during his career.
Electronics, 1961.

Yume Cyan shot these incredible long-exposure photographs of fireflies in the forests surrounding Nagoya City in Japan. Fireflies have specialized light-emitting organs in their lower abdomens which create a chemical reaction leading to light. Specifically, an enzyme called luciferase acts on luciferin, in the presence of magnesium ions, ATP, and oxygen to produce light. But WHY do these bugs create light? buy kamagra online https://www.sanjeevanam.com/products/wp-content/languages/new/kamagra.html no prescription
They have a variety of ways to communicate with mates in courtships: steady glows, flashing, and the use of chemical signals unrelated to photic systems.” It sounds a bit like the Morse Code of sex.
Apparently, Yume headed to the forest in the Spring of this year during the beginning of the rainy season to catch the fireflies as they mate after thunderstorms.
“China Danxia is a UNESCO World Heritage Site and the name given in China to landscapes developed on continental red terrigenous sedimentary beds influenced by endogenous forces (including uplift) and exogenous forces (including weathering and erosion). The inscribed site comprises six areas found in the sub-tropical zone of south-west China. buy penegra online https://www.sanjeevanam.com/products/wp-content/languages/new/penegra.html no prescription
NASA was officially created on October 1st, 1958 to “provide for research into the problems of flight within and outside the Earth’s atmosphere, and for other purposes.” However, space and aeronautics research was being conducted for several decades before NASA’s inception under the guidance of NACA, the National Advisory Committee for Aeronautics.
The images seen here are just a sample of the gorgeous photographs taken during the infancy of the United States Space Program.

(August 25, 1949) An engine mechanic checks instrumentation prior to an investigation of engine operating characteristics and thrust control of a large turboprop Python engine with counter-rotating propellers under high-altitude flight conditions in the 20-foot-dianieter test section of the Altitude Wind Tunnel at the Lewis Flight Propulsion Laboratory of the National Advisory Committee for Aeronautics, Cleveland, Ohio, now known as the John H. Glenn Research Center at Lewis Field.
The United States had a clear goal — beat the Russians the Moon — and in 1969, we succeeded. However, I can’t help but feel our space program has been a bit lost ever since…
I suggest listening to a few of the songs while watching the animations. And, if you want to build your own helmet, check out the RobotSpaceBrain Official Tutorial.
