What is Space? Radiation invisible to human eyes. Most of space is relatively empty, meaning that there are just stray bits of dust and... Black holes. Smaller black holes can form from the gravitational collapse of a gigantic star, which forms a singularity... Stars, planets, asteroids and comets…
What's in Space? When you look up at the night sky, you see stars and sometimes the moon and the brighter planets. Away from city lights, on a clear night, you might see the beautiful band of the Milky Way, stretching across the sky. Is there anything else up there in space?
A common definition of space is known as the Kármán Line, an imaginary boundary 100 kilometers (62 miles) above mean sea level. In theory, once this 100 km line is crossed, the atmosphere becomes too thin to provide enough lift for conventional aircraft to maintain flight.
In space, astronauts are exposed to varied and increased levels of radiation that are different from those on Earth. Three major sources contribute to the space radiation environment: particles trapped in Earth’s magnetic field, solar energetic particles from the Sun, and galactic cosmic rays.
Scientists define the beginning of interstellar space as the place where the Sun’s constant flow of material and magnetic field stop affecting its surroundings. This place is called the heliopause. It marks the end of a region created by our Sun that is called the heliosphere.
NASA stands for National Aeronautics and Space Administration. NASA is a United States government agency that is responsible for science and technology related to air and space. The Space Age started in 1957 with the launch of the Soviet satellite Sputnik. NASA was created in 1958.
NASA is building another space telescope. It is called the James Webb Space Telescope. It will be bigger than Hubble. Webb will not orbit Earth as Hubble does. Webb will orbit the sun in a spot on the other side of the moon. The Webb telescope will be able to see a different kind of light than the light Hubble sees.
