Paleontological Evidences Harbor Life of Planet Earth

Abstract According to solar nebula structured ,our planetary system bear from accretion of the dust particles and planetesimal period, after that condensation in solar nebula. Thus most of celestial bodies of our planetary system, like planet, natural satellite, comet, meteorite & asteroids exhibit the different kind of planetary habitable. Base on energy source as a sun like star, carbon as a most prominent element of life forms on earth & percentage of liquid water which consist of celestial bodies. Due to study of the origin, evolution, distribution & future of life in universe , earth is the only place know to harbor life. It is depend on minimal condition for life such as temperature, water, radiation shielding, the stuff of life , sunlight, oxygen, when planet belongs...

Mars Perseverance Rover Safely Lands on Red Planet

The largest robot  rover, NASA's largest spacecraft, was launched in March on Thursday, after a 203-day journey across 293 million miles (472 million kilometres). Confirmation of a successful touchdown was announced at NASA's Jet Propulsion Laboratory mission in Southern California at 3:55 p.m. EST (12:55 pm PST). Filled with landslide technology, the Mars 2020 missile launched on July 30, 2020, from the Cape Canaveral Space Force Station in Florida. The Perseverance rover mission marks the first step in the effort to collect Mars samples and return them to Earth. Approximately the size of the rover, a 2,263 robotic geologist (1,026 pounds) and an astronomer will be examined a few weeks before we begin its two-year scientific investigation of Mars ’Jezero Crater. While the rover explor...

Meteorites : An introduction to Astrobiology & Concepts 02

Ameteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon In his booklet, "On the Origin of the Pallas Iron and Other Similar to it, and on Some Associated Natural Phenomena", published in 1794,he compiled all available data on several meteorite finds and falls.Ernst Florens Friedrich Chladni (Father of Meteoritics). From this, he was forced to conclude that meteorites were actually responsible for the phenomena known as fireballs, and, more importantly, that they must have their origins in outer space. Fossil Meteorites "Fossil" meteorites are sometimes discovered by Exo geologists & Astrobiologist . They represen...
