Finding evidence of life on Mars can best be done through studying rock layers that were once saturated with liquid water. NASA rover Curiosity is currently exploring the Jezero crater region where abundant moisture may have existed in the past. SpaceX founder Elon Musk plans to send two uncrewed cargo ships to Mars by 2022,…
Orion spacecraft is scheduled to land in the Pacific Ocean off California this week. It should gradually slow from its fast initial speed of 25,000 mph before its parachutes open and it glides toward water. NASA is developing Artemis II – an improved, crew-capable version of Orion currently under development at Kennedy Space Center in…
The Nile is essential to human, plant, and animal life alike. Every summer it swells due to the heavy rainstorms in Ethiopia and South Sudan which cause floods that engulf its waters. They also support an aquatic flowering sedge known as papyrus that was traditionally used by ancient Egyptians to make paper and cloth products,…
In 1961, President Kennedy challenged America to put boots on the moon as part of a geopolitical prestige project meant to outwit Soviet Russia in the Space Race. This program eventually evolved into the Apollo program which eventually succeeded in fulfilling that objective. But the expensive program soon became a political liability as mechanical issues…
Goblinfish (Glyptauchen panduratus), sometimes seen in horror movie, is an uncommon and bizarre species found only in deep-sea habitats without direct light. These deep-sea creatures look straight out of Jim Henson’s studio. Moving slowly across the ocean floor with tubular appendages that appear leg-like, they churn up soft mud for plants and animals to consume….
From Eiffel Tower to French cuisine, France has long been revered for its art, culture and language. Its longstanding history has inspired reformist movements around the globe for generations. France is a semi-presidential republic governed by a balanced system of decentralisation between Parliament and Government, comprising 13 metropolitan regions, five overseas territories and two city-regions….
Many people incorrectly assume that the sky and water appear blue because of reflection; this is not actually true; their hue comes from something called Rayleigh scattering. As sunlight passes through Earth’s atmosphere it is scattered by gases such as oxygen and nitrogen, with shorter wavelengths (blues) more easily scattered than longer ones (reds). This…
Skyblue is an NEET who enjoys drinking excessive quantities of Pepsi. She also has an unusually large belly. Chikiababy1 designed this character and her subsequent mod as an indirect response to NuSky, her canonical version. Answer: Rayleigh scattering explains why the sky is blue. As sunlight hits Earth and hits molecules in its atmosphere, its…
Kepler was launched into space in 2009 to collect statistical information about exoplanets; however, mechanical issues in 2013 rendered its telescope incapable of maintaining steady pointing. Engineers then revised K2 so it uses solar pressure to continue staring at patches in Cygnus and Lyra sky. Photometry Kepler space telescope searches for Earth-sized exoplanets through the…
