Sunlight travels through Earth’s atmosphere where it is redirected by gas molecules and small particles into various directions, with blue wavelengths becoming scattered more readily than others, giving the sky its characteristic color during daylight hours. Sunrise and sunset sunlight must pass through more of the atmosphere, leading to more blue being scattered away and…
Like Earth, Mars rotates and completes one day every 24 hours; however, their solar day, known as sol is 39 minutes longer. Astronomers typically refer to Mars days in terms of solar days. This can lead to confusion when planning space missions. Seasons Mars may often be considered Earth’s twin, yet its features remain distinct….
Once upon a time, Mars was an expansive, lush planet filled with canyons and lakes. But over time it cooled, its magnetic field dissipated, and streams of ionizing radiation began stripping its atmosphere away. Today it’s an inhospitable desert. MGS has observed many different kinds of PADs across many regions, which has enabled researchers to…
Color is more than simply one hue; understanding their interactions is crucial for creating presentations and selecting a color palette for projects. Tyndall and Rayleigh believed that the blue color of the sky must be due to microscopic particles of dust or droplets of water vapour in the atmosphere. Blue Light Light from the sun…
Since 1610, when scientists first made telescopic observations of Mars through telescopes, scientists have been mapping and studying it. Recently, three missions – China’s Tianwen-1 probe, United Arab Emirates Hope probe and NASA Perseverance rover – have used Mars’ 26 month orbital period to gather new information. Orbiters have provided more clarity, disproving theories about…
Sunlight from the sun passes through our atmosphere and becomes dispersed, with shorter wavelengths like blue being scattered more widely than other colors. Blue light must travel further through the atmosphere than other colors, which explains why the sky appears blue. Rayleigh Scattering Sunlight passing through Earth’s atmosphere is scattered by molecules and particles in…
As NASA’s Mariner IV probe returned images of Mars to earth, people worldwide watched with anticipation as the planet revealed itself to them for the first time ever. What they discovered was unimaginable to most. Planet Earth features polar caps, volcanoes, canyons and deserts – in addition to two small moons: Phobos and Deimos. Images…
Mars has long been of interest to scientists and astronomers. As one of our nearest neighbors, this planet holds many mysteries to reveal. Mars is an extremely cold planet located much further from the sun than Earth. Mars, known for its fiery hue, stands as a powerful and brave symbol. Astronomy Mars, located fourth from…
Mars has long captivated scientists, explorers and movie makers. Although it shares many characteristics with Earth, there are notable distinctions. Scientists theorize that Earth was formed along with other rocky planets within an inner part of a giant disk of gas and dust that later flattened out to form our Solar System. Earth features two…
