Space exploration and tourism is currently undergoing an incredible revolution: globalizing, shifting to become a service industry and welcoming in newcomers into its fold. During the Gulf War, allied forces used satellites to accurately pinpoint enemy troops and target their rocket attacks with pinpoint precision – demonstrating the value of space presence even during warfare….
Volcanoes provide us with incredible access to Earth’s living interior, but they can also be extremely dangerous. Temperature variations within magma can have an effect on how it erupts; for instance, lavas with greater silica content tend to erupt less explosively than their counterparts with lesser silica content. Scientists use seismometers and other monitoring instruments,…
Answer: Oxygen and nitrogen molecules in the atmosphere scatter sunlight incoming, with blue wavelengths being scattered more often than red ones resulting in the sky appearing bluer than usual. But this explanation doesn’t explain why the sky doesn’t turn violet at sunset or why Martian skies have an earth-tone hue; that is because sunlight must…
Great white sharks offer more than they’re given credit for; they aren’t simply the intimidating monsters seen in movies; instead, they’re intelligent predators with stunning intelligence. Humans possess an amazing sense of smell and even possess the capability of sensing electricity with their noses! In fact, they contain pores on their snouts which allow electromagnetic…

Rivers are one of the planet’s most fascinating geological features, creating landscapes, canyons, carrying people and goods through many countries (think Nile River to Ancient Egyptian civilization or Danube in Europe!) Rivers play an invaluable role in human civilization – look no further than ancient Egypt where river transport was vital to their economy! As…
Scientists have long studied Mars by peering through telescopes, orbiting it with spacecraft and sending rovers onto its surface. Through their work they’ve discovered many similarities between our world and Mars’. Planet Venus shares similar dimensions, gravity and composition with Earth; yet has unique features of its own such as an oblate spheroid shape and…
Spacecraft are vessels specifically engineered for travel and operation in outer space, featuring life support systems, science instruments and accommodations for crew. Some spacecraft are unmanned while others can carry people. Manned spacecraft are used to fly astronauts directly to the International Space Station and other planetary destinations while unmanned ones conduct scientific research. Aldrin…
Humanity longs to feel as if we can travel amongst the stars, yet this image of an astronaut looking back towards Earth illustrates just how far that goal really is. NASA’s OSIRIS-REx spacecraft is on its way to visit Bennu asteroid, taking this black-and-white image en route. Red Rectangle Astronomers have for more than three…
