Our Planet [Our Solar System]

 Our Solar system is one of over 500 known solar systems in the entire Milky Way galaxy the solar system came into being about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed resulting in a solar nebula a swirling disk of material that collided to form the solar system the solar system is located in the Milky Way's. Orion star cluster only 15% of stars in the galaxy host planetary systems and one of those stars is our own Sun revolving around the Sun are eight planets the planets are divided into two categories based on their composition terrestrial and Jovian terrestrial planets including Mercury Venus Earth and Mars are primarily made of rocky material their surfaces are solid they don't have ring systems they have very few or no moons and they are relatively small the smallest and closest to the Sun is mercury which has the shortest orbit in the solar system at about 3 earth months. Venus is the hottest planet with temperatures of up to 867 degrees Fahrenheit due to an atmosphere of carbon dioxide and extensive lava flows next to this world of fire is a world of water earth the water systems on this planet helped create the only known environment in the universe capable of sustaining a life the last of the terrestrial planets Mars might have also supported life about 3.7 billion years ago when the planet had a watery surface and moist atmosphere beyond the four terrestrial planets of the inner solar system lie the Jovian planets of the outer solar system the Jovian planets include gas giants Jupiter and Saturn and ice giants Uranus and Neptune the gas giants are predominantly made of helium and hydrogen and the ice giants also contain rock eyes and a liquid mixture of water methane and ammonia all four Jovian planets have multiple moons sport ring systems have no solid surface and are immense the largest Jovian is also the largest planet in the solar system Jupiter nearby is Saturn the solar system's second largest planet its signature rings are wide enough to fit between earth and the moon but are fairly a kilometer thick past Saturn are the ice giants Uranus and Neptune the slightly bigger of these ice giants Uranus is famous for rotating on its side next to Uranus is Neptune the outermost planet in the solar system and also one of the coldest orbiting the terrestrial planets is the asteroid belt a flat disc of rocky objects full of remnants from the solar system's formation from microscopic dust particles to the largest known object the dwarf planet Ceres another disk of space debris lies much further out and orbits the Jovian planets the icy Kuiper belt apart from asteroids the Kuiper belt is also home to dwarf planets such Pluto and is the birthplace of many comets beyond the Kuiper belt is the Oost cloud a vast spherical collection of icy debris it is considered the edge of the solar system since that is where the gravitational and physical influences of the Sun end our solar system's particular configuration of planets another celestial objects all revolving around a life-giving star make it a special place to call home

Volcanoes [History of Volcanoes]

Portals into  the guts  of  the world  they burned bottomless cauldrons fueled by an ancient wrath bubbling and boiling thousands of miles beneath the surface and just waiting to burst through volcanoes are scattered across the planet about 1,500 active volcanoes can be found across  the planet  though countless others are on the  ocean bottom most volcanoes whether  ashore  or underwater are located where tectonic plates meet  actually  the Ring  of fireside  a path that traces the boundaries between several tectonic plates  round the Pacific Ocean contains about 75% of the planets volcanoes there are several types of volcanoes primarily classified by shape and size major types include stratovolcanoes  which frequently  appear as tall steep mountains shield volcanoes which are flatter and dome shaped calderas which are large depressions in the ground and mid-ocean ridges which are...

COVID-19 (Coronavirus Disease 19) March Update- causes, symptoms, diagnosis, treatment, pathology

By Now you've probably heard of Covid-19 or corona virus disease discovered in 2019 which is responsible for a global pandemic Covid-19 is caused by SARS COV 2 or severely acute respiratory syndrome corona virus - because it's genetically similar to the Sarris corona virus which was responsible for the SARS outbreak in 2002 now corona viruses that circulate among humans are typically benign and they cause about 1/4 of all common cold illnesses in Covid-19 what happened is that there was a corona virus circulating among bats which are a natural animal reservoir and it mutated just enough to start infecting an intermediate host the Pangolin an animal that looks like a cross between an anteater and an armadillo in late 2019 the corona virus mutated again and started causing disease in humans the outbreak began in China but has since spread around the world as of March 9th 2020 or roughly three months into the outbreak there have been 109 thousand five hundred and seventy-eight ...
