Mars stands out in our solar system as one of its brightest planets, boasting a reddish surface dotted with craters and giant volcanoes such as Olympus Mons. Mariner space probes provided us with our first close-up images of Mars in 1965, and since then scientists have studied it carefully, uncovering evidence of past life on…
Every flowering plant begins as a tiny seed. Through sunlight, water, and soil conditions, this seedling germinates into an attractive sprout or seedling with stems and roots to absorb nutrients while leaves capture sunlight for photosynthesis and create food by photosynthesis. Flowers contain male sexual parts (anthers) and female sexual parts (pistils). Pollen from the…
Butterflies are beloved insects that captivate with their vibrant wings. However, butterflies also undergo an amazing metamorphosis process, one of the main ways biologists define life. A butterfly begins its life as an egg, developing into a caterpillar or larva before eating and shedding its skin several times until finally reaching its final form –…

People typically spent their free time listening to brass bands or attending shows which featured hypnotism or communing with the dead through mediums. Steam power enabled mass production – the simultaneous manufacture of multiple products at once –…
NASA’s Apollo program was its flagship effort in the 1960s and ’70s for human exploration of space, using Saturn family rockets to send 12 crewed missions to land humans on lunar surfaces and 1 uncrewed test flight. Apollo 1 was the inaugural crewed mission, yet tragically failed when its crew module caught fire during a…
As sunlight travels through the atmosphere, its light is scattered by air molecules and particles, with shorter wavelengths such as violet and blue being dispersed more widely than longer ones (red). Sky blue color comes from sunlight which has passed through our atmosphere; lunar illumination does not have this same impact, since its beam hasn’t…
Scientists find many things fascinating – from atoms and outer space to the human body itself. Yet none are more astonishing than our bodies themselves. Did you know that, on average, you blink approximately 20 times per minute? Or that it takes more muscles to frown than smile? Or that earwax is actually a form…
Viewed from above sea level, the sky takes on an even darker blue color as more blue wavelengths get scattered through the atmosphere than other hues. Rayleigh scattering, which affects all gases smaller than light wavelengths, plays a part. Light Wavelengths Sunlight contains all of the colors of the rainbow – including blue – which…
