Nuclear radiations generally come from radioactive substance those radioactive substance may be present at any where in space. Sun also has such radioactive substances which gives raises to fusion reaction in it. So nuclear radiation may be from any part of the space it may be from the nearby planet or from star, etc,.
Texas is the only US state that allows its residents to cast absentee ballots from outer space. This law was passed in 1997 to accommodate astronauts from NASA's Johnson Space Center in Houston.
Radiation in space primarily consists of high-energy particles, such as cosmic rays and solar radiation, which can travel through the vacuum of space at the speed of light. Unlike on Earth, where the atmosphere protects us from harmful radiation, space lacks such shielding, exposing spacecraft and astronauts to increased levels of ionizing radiation. This radiation can damage living cells and electronic components, necessitating protective measures in spacecraft design. Additionally, radiation can affect the behavior of materials and influence the conditions for life beyond Earth.
Exploring outer space can lead to new scientific discoveries, advancements in technology, and a better understanding of our place in the universe. It also offers opportunities for economic growth and innovation. Additionally, studying outer space could help us prepare for potential future scenarios like asteroid impacts or climate change.
Heat transfer through empty space is known as radiation. It does not require a medium (such as air or water) for heat to travel and can occur in a vacuum. This type of heat transfer is how the sun's energy reaches us on Earth.
Stars are constantly emitting solar radiation, or CMEs (coronal mass ejections). Earth is a target to solar radiation, but fortunately most radiation is either deflected Earth's magnetic field or ozone layer protecting us from it. Solar radiation is dangerous and lethal in outer space if exposed to it. Earth's magnetic field directs solar radiation to the poles and when it reacts with the atmosphere it lights up and creates the northern lights.
The first animal sent to Outer space was a dog named Laika.
125
They went into outer space in 1973
They are important because it is the one who bring us to outer space.
Everyone needs to be protected against radiation, because radiation in strong doses can Kill or injure. A small amount that a person receives in an x-ray will do no harm; but, too strong a dose of radiation is very dangerous. Radiation is greater in outer space than it is on the earth, because, we are protected from radiation on earth by the atmosphere. Astronauts in outer space have no such protection.
The heat energy comes from the Sun to us via electromagnetic radiation, mainly light, which can propagate through empty space.
The ozone layer protects us from the harmful radiations of the sun. This ozone layer is present in the stratospheric region of the atmosphere.
After the lecture, students often bombard the teacher with questions. The boys like to bombard each other with snowballs. If you bombard him with praise, he'll keep doing well. I wish politicians wouldn't bombard us with commercials before every elections. The policy will change if we bombard the manager with complaints.
An astronaut.
we didn't the USSR did
Space Exploration did not begin in the US. The first country to successfully launch a human into outer space was the Soviet Union.
it makes a magnetic field protecting us from the spaces radiation
