Zebras are one of the most majestic and breathtaking animals found in Africa. People have long been mesmerised by these gorgeous animals with stripes that continue to perplex minds! Researchers have recently discovered that the stripes on zebras can actually help confuse predators when running, by creating a motion dazzle effect and disorienting their vision!…
As sunlight enters Earth’s atmosphere, its light is dispersed through gases and particles in the atmosphere by various gases and particles; light toward the blue end of the spectrum is scattered more widely than red end light, giving Earth its signature blue hue. As writers, it is our responsibility to pay close attention to reader…
NASA’s Cassini spacecraft has been studying Saturn’s rings and moons for 13 years, and recently released findings provide insight into their formation, evolution, and how they change over time. New research suggests the rings may be much younger than scientists previously assumed, based on an association between mass of rings and how quickly they become…
NASA’s Apollo program consisted of six missions which used command modules and lunar modules to land astronauts on the Moon. On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin set sail from Columbia’s command module and entered their lunar module Eagle, landing successfully and surveying its surface before calling home: “Houston Tranquility Base here:…
Giraffes are incredible animals to observe. Boasting long necks, long tongues and adorable tufty horns – not to mention being quick runners over short distances! – they make for quite the spectacle! Giraffes are known for humming at night in order to communicate with other giraffes or simply stay awake. This could be either to…
Spacecraft electric propulsion uses solar array power to ionize and accelerate inert gas propellants like Xenon (no, not from Superman’s home planet) for propulsion by Hall and gridded ion thrusters that gradually speed the spacecraft along its journey. EP systems possess very high specific impulse, or the amount by which a change in speed alters…
Like Mercury, rocky planets may undergo changes due to internal forces which push and pull at crustal material, creating landforms such as volcanoes, mountains, and canyons. These forces are known as tectonics and may contribute to landform formation such as volcanoes. Scientists have various hypotheses as to what caused Mercury’s scarred surface, one being its…
An adult butterfly goes through four distinct stages to reach adulthood: egg, larva, pupa and finally butterfly. Female butterflies lay eggs on specific host plants. After hatching into larva, these feed and grow. Over time, their skin sheds multiple times in what’s known as molting. Eggs At the outset of butterfly life cycles, female butterflies…
What is Bluesky? Bluesky may resemble Twitter at first glance, with users being able to post up to 300-character messages and toggle between an algorithmic feed and chronological feed. But Bluesky stands apart by being decentralized compared to Mastodon which requires joining servers, giving a similar experience like Reddit but allows users to create their…
