Simple Science Thoughts

The simple explanation for the Red Planet's color is that its regolith, or surface material, contains lots of iron oxide — the same compound that gives blood and rust their hue.Aug

There is now a scientific consensus that the blood rain phenomenon is caused by aerial spores of green microalgae Trentepohlia annulata. ... Today, the dominant theories are that the rain is caused by red dust suspended in the water (rain dust) or by the presence of micro-organisms

Animals have keen senses that help them avoid predators or locate prey. It is thought that these senses might also help them detect pending disasters. ... One theory is that animals sense the earth's vibrations. Another is that they can detect changes in the air or gases released by the earth.

They have a totally different voice box than humans, which gives them much more control over their vocal tract. The syrinx is responsible for birds' incredible range, the ability to produce two sounds at once, and why they can sing continuously. Some birds use this unique physiology to mimic.

Neutron stars can be dangerous because of their strong fields. If a neutron star entered our solar system, it could cause chaos, throwing off the orbits of the planets and, if it got close enough, even raising tides that would rip the planet apart.

Trees are a crucial part of the carbon cycle, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. ... Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen.

By 2020, the Tian Fu New Area Science Society plans to launch an artificial moon to light up the night sky. If the plan goes through, the so-called “illumination satellite” would orbit above the Chinese city of Chengdu and glow in conjunction with the actual moon, but shine eight times brighter.

By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.

Over time, swashbucklers who often found themselves embroiled in combat had learned how to adapt. Of course, the only way to move stealthily through the dark of night was to utilize your eyes to the fullest. By wearing a patch over one eye, pirates could “trick” their vision into adjusting to darkness more quickly.

A volcano is any hole or rupture in planetorial mass ( ex. Earth ) that forms when a liquid rock called magma surfaces and piles eventually forming a mountain. Volcanoes only form during plate boundaries. There are at least 1500 mountains confirmed volcanic on earth. Among them are 500 active.
