A mushroom is a fleshy spore-bearing fruting body of a fungus, normally produced above ground, on soil or on meal sources. They are so popular that even a child can identify one, they also have many benefits to humans and the ecosystem.

They also have an umberlla shape, which is on of their striking features and that is what this article aims at explaining. But before that, we first need to know this organism better, and that will be done in the next paragraphs, so sit back and enjoy.

Mushrooms are a type of fungi, and they are the most advanced type of fungi on earth today. They can reach significant sizes and have a well developed reproductive system. The mushroom is more than just the part of the organism you see, there is  a complex network of hyphae (collectively called mycelium) underground or on the dead orgainsm they live on since they are saprophytic organisms. Mushrooms are also a healthy addition to the humans diet, they are amongst the few eadible fungi on earth. 

Now that you understand mushrooms, what do you think that weird umbrella shape at the top of the mushroom and it's use? Well just beneath the umbrella of of a mushroom, is a sophisticated reproductive organ that produces and help dissipate spores (mushroom seeds).

The mushroom needs to have an umberlla shape to protect it's reproductive organ located just beneath it's umbrella shaped head. This organ is so important to the mushrooms that it may not exist without it.

A study is challenging the prevailing hypothesis on why Mercury has a bigger core relative to the planet' s mantle. Scientists, for decades, have argued that the hit- and- run collisions on other celestial bodies during the early days of the solar system blew off much of Mercury' s rocky mantle leaving only its big, dense, metalcore. However, new research reveals that collisions are not as much to blame as the Sun' s magnetism

Mercury, the planet nearest to the sun and the smallest planet in the solar system, is only slightly bigger than the Earth' s moon. From its surface, the sun appears to be three times larger than how it is seen on Earth with the sunlight radiating seven times brighter.

Contrary to popular belief and its proximity to the sun, Mercury is not the hottest planet in the solar system. This title rightfully belongs to Venus, mostly due to its dense atmosphere.

According to NASA, a day on Mercury takes roughly 59 Earth days. Where the planet completes an orbit around the Sun in 88 Earth days. Compared to Earth, Mercury has a thin atmosphere composed primarily of oxygen, sodium, helium, hydrogen, and potassium.

An interesting fact about Mercury is that it has no satellites or moons. No evidence of life has ever been observed on the planet whose daytime temperatures can reach 430 degrees Celsius and drop to 180 degrees Celsius below 0.

William McDonough, lead author, and a geology professor at the University of Maryland, Takeshi Yoshizaki from the Tohoku University developed a density, mass, and iron content model of the rocky planet' s core that was influenced by the distance between the planet and the sun' s magnetic field.

The paper published in the journal Progress in Earth and Planetary Science, entitled " Terrestrial planet compositions controlled by accretion disk magnetic field" describes how the model challenges conventional hypothesis on Mercury' s mantle and core composition.

McDonough explains that the four inner planets of the solar system— Mercury, Venus, Earth, and Mars— consist of varying proportions of rock and metal. A gradient exists where the metal contents in the planet' s core drop off as each planet gets farther from the Sun. The paper explains how the phenomenon occurred by showing the distributions of raw materials during the early days of the solar system when the Sun' s magnetic field controlled the formation.

The model shows how during the early days of the solar system, when the young sun was engulfed in swirling clouds of gas and dust, grains of iron were dragged toward the Sun' s magnetic field. As the planets began to form from the clumps of dust and gas, planets closer to the sun began to incorporate more of the iron into their respective cores than those that were formed farther away.
