Space


What is space?

Space is area where is possibility of atmosphere is very less. It is mainly a vacuum. in space no one cannot hear a sound waves because sound need medium to travel but space is vacuum where no air is present

outer space begins about 100 km above the Earth where the shell of air around a planet, disappears as result there is no air  scattering of the sun light  which appears the sky blue not happen, and the blue sky becomes dark sky.

Space usually regarded as completely vacuum but it is not true there is vast gaps between stars and planet are filled with huge amount of gas, dark matter(not discovered having possibility discover)  and dust Even the emptiest parts of space contain at least a few hundred atoms or molecules per cubic metre.   

Space also consist radiation like x rays, gamma rays, infrared rays, cosmic rays and uv rays which is harmful for astronauts much of radiation like infrared rays and uv rays come our solar system sun other high energy rays like cosmic rays, gamma rays and x rays (particles travelling close to the speed of light) are arrived from distant solar system or star system

  Mercury          Mercury is the closest to the sun and first, no moon, terrestrial planet and smallest  planet of solar system. it revolve the sun faster than all the other planets, which is why Romans named it after their swift-footed messenger god. The Sumerians also knew of Mercury since at least 5,000 years ago. It was often associated with Nabu, the god of writing . Mercury was also given separate names for its appearance as both a morning star and as an evening star. Greek astronomers knew, however, that the two names referred to the same body, and Heraclitus, around 500 B.C., correctly thought that both Mercury and Venus orbited the sun, not Earth. NASA's MESSENGER spacecraft orbited Mercury for more than four years. this spacecraft is launch by Delta 7925H And it 1,107.9 kilograms  Among its accomplishments, the mission determined Mercury’s surface composition, revealed its geological history, discovered details about its internal magnetic field, and verified its p

The Black Knight Satellite: A Hodgepodge of Alien Conspiracy Theories The Black Knight satellite conspiracy theory claims that a spacecraft of extraterrestrial origin is in near- polar orbit of the Earth, and that NASA is covering up its existence and origin. This conspiracy theory combines several unrelated stories into one narrative. A photo taken during the STS-88 mission claimed by some to show the Black Knight satellite is catalogued by NASA as a photo of space debris, and space journalist James Oberg considers it as probable debris of a thermal blanket confirmed as lost during the mission.                    Take a good look at the photograph above. NASA captured this image of a mysterious black object orbiting the Earth in 1998, during the first Space Shuttle mission to the International Space Station (ISS). The space agency refers to the strange entity as item STS088-724-66 in its catalogue of space junk floating in low-Earth orbit (within 1,200 miles ). Jerry Ros

Venus     It's a cloud-swaddled planet named for a love goddess, often called Earth’s twin. But pull up a bit closer, and Venus turns hellish. Our nearest planetary neighbor, the second planet from the Sun, has a surface hot enough to melt lead. The atmosphere is so thick that, from the surface, the Sun is just a smear light. In some ways it is more an opposite of Earth than a twin: Venus spins backward, has a day longer than its year, and lacks any semblance of seasons. It might once have been a habitable ocean world, like Earth, but that was at least a billion years ago. A runaway greenhouse effect turned all surface water into vapor, which then leaked slowly into space. The present-day surface of volcanic rock is blasted by high temperatures and pressures. Asked if the surface of Venus is likely to be life-bearing today, we can give a quick answer: a hard “no.” Further, Venus may hold lessons about what it takes for life to get its start ­– on Earth, in our solar
