Blue is a relaxing color that inspires trust and calmness, representing water and the sky. Let these hilarious blue jokes add some humor and relaxation into your day! The sky appears blue due to sunlight being scattered by gases and particles in the atmosphere, allowing only shorter wavelengths from reaching our eyes and creating what…
Have you seen satellites zipping across the sky, taking minutes to travel from horizon to horizon? They appear tranquil but in reality are moving at hundreds of kilometers per second! Satellites help us explore our world and solar system with greater depth. They provide weather forecasts, route cell phone calls, and take pictures of Earth…
Before recently, Venus was considered a low priority planet to explore; however, the discovery of phosphine on Venus has reignited interest in this hellish realm. Ancients believed Venus had an environment similar to Earth with jungle-like foliage and carbonated oceans, but radio observations of brightness temperatures suggested otherwise – suggesting its surface must have been…
Mars can be seen with the naked eye throughout most of the year and becomes easier and brighter to identify during oppositions, when Earth and Mars come closest together on their orbital paths around the Sun. Planet Earth’s surface is reddish brown in hue and covered with black volcanic sand and dark basalt rocks that…
For spacecraft to reach Mars, they must first escape Earth’s gravity by using powerful rocket fuel and launch at exactly the right moment – both planets orbit around the Sun at different speeds and distances; every 26 months or so they come closer together, making travel to Mars much simpler. Spirit A six-wheeled vehicle equipped…
Apollo 11 immediately captured world imagination upon launch, drawing global interest as Neil Armstrong and Buzz Aldrin embarked upon mankind’s first steps ever on the Moon. It made history. They disassociated Eagle from Columbia, and began exploring the Moon’s surface. Furthermore, they deployed scientific equipment and collected samples of lunar materials. Launch Apollo 11 was…
Last week, scientists announced the discovery of an Earth-like planet orbiting Proxima Centauri — our closest star and source of life — which might support life. This exoplanet represents one of the nearest possible candidate planets for human habitation ever found so far. But how close are we cosmically speaking? To answer that question, we…
As Eagle neared the moon, program alarms continued to interfere with communication with Mission Control and propellant was seen sloshing around due to low fuel levels. Further increasing tension was the fact that program alarms continued sporadically interrupting radio transmissions with Mission Control. Two minutes of radio silence ensued – which has since been exploited…
Children are naturally curious about their world. A question often raised is: Why is the sky blue? Light is scattered as it travels through the atmosphere by air molecules; blue wavelengths tend to be more strongly scattered. The Sun’s Light The Sun emits light over an array of wavelengths (or colors). Our eyes, however, perceive…
