The sky’s distinctive blue hue results from scattered sunlight. When sunlight strikes atmospheric particles such as nitrogen and oxygen molecules, their molecules scatter it with more blue wavelengths. Blue wavelengths tend to scatter more easily than red ones; this phenomenon is known as Rayleigh scattering. The Sun The Sun is responsible for giving the sky…
Spacecraft are vehicles designed to carry humans safely into space and back down again without crushing them during launch, reaching their destinations alive and undamaged, before returning safely back down again. Spacecraft have been deployed across our solar system and beyond in order to investigate other bodies in our galaxy and beyond. While some remain…

Are You Wondering Why the Sky Is Blue? (Ps. 417)? : Many have pondered this question since mankind first explored space. As light enters the atmosphere, it interacts with air molecules primarily composed of nitrogen and oxygen atoms that scatter its various wavelengths; this allows blue light waves to travel further than others. It’s a…
Rome wasn’t built overnight; and neither was its epic history. It tells the tale of how a small village became one of the greatest empires on Earth. Romans were well known to display a more wild side than most cultures; their sexual appetite for women was especially notorious – legalization allowed for multiple mistresses per…
As rocket engines open their nozzles and unleash thrust, Newton’s third law comes into effect: for every action taken there will be an equal and opposite reaction. Sandra Bullock’s fire-extinguisher from Gravity worked due to being pushed against an object; but is that possible in space where there’s nothing for it to push against? Chemical…
Spring can be seen everywhere – from snowdrops dotting the forest floor to jelly-like frogspawn in your local pond, and even trees like alders (with their long male catkins) sending up signs that it is time for new growth and blooming buds to appear as classic indicators of change. Keep an eye on the skies…
By monitoring seismic waves that were transmitted through Mars’ interior, scientists discovered a layer of molten rock surrounding its liquid metal core – thus challenging current theories about its structure and evolution. This new discovery could help scientists gain a greater understanding of how Mars formed, evolved and lost its capacity for life over time….
Insects are some of the most fascinating animals on Earth, boasting an amazing diversity. While most insects share common traits such as hard exoskeletons and three body segments (head, thorax and abdomen), each insect also stands out in their own special way. Did you know, for instance, that praying mantis can swivel their heads 180…
