Longer than those emitted by the Sun
Wein's Displacement Law explains the difference between long and shortwave radiation. Shortwave radiation has shorter, more high energy wavelengths (stronger with less distance to travel) while longwave radiation travels farther, but has less energy. Earth's radiation is 20 times longer than the maximum solar radiation, so it is referred to as longwave, while solar energy is referred to as shortwave radiation.
Space shuttles are not designed to operate outside of a low-earth orbit, where they are protected from deadly radiation by the earth's magnetic field; a mission to Sirius by a space shuttle is not even possible.

Infrared radiation is long wavelength radiation given out by stars.
Distance from the earth to the sun is about 93,000,000 miles. The speed of light is about 186,000 miles/second or about 8 minutes, 20 seconds.
The energy that doesnt reach earth just goes out into the universe. Say that energy comes from the sun, well by the time it would've reached earth it would've spanned and expanded out so we (earth) would only receive a portion of the energy than what was previously released from the sun. :)
because they do not go to the same direction e.g the short-wave radiation heats the earth and the long-wave radiation heats the atmosphere.
Terrestrial radiation refers to heat emitted from the earth's atmosphere and surface.
The radiation emitted by the Earth peaks around 10 microns, whereas that from the sun peaks under 1 micron. This is why Earth's radiation is referred to as longwave and solar radiation as shortwave, commonly. All objects emit radiation because all objects have a temperature. In fact, using Wien's Law you can very simply calculate the wavelength, lambda, of maximum emission: lamda(max) = c/T where c is a constant (2897) and T is the temperature of the emitting surface in Kelvin.
Radio waves are at the long wavelength end of the sun's emissions.
The atmosphere easily transmits shortwave radiation from the Sun, BUT is a poor transmitter of LONG-WAVE radiation from Earth's surface. This selective transmission causes the Greenhouse effect in the atmosphere.
The type of electromagnetic waves that will be emitted by a cooler object are waves with long wavelengths. The wavelength of peak emission is determined by Wien's Law.

Long wave radiation emitted by the sun reflects off earth's surface and is absorbed by heat trapping gas in the atmosphere. Nitrogen and oxygen do NOT absorb infrared radiation, but CO2, CH4, and H2O DO trap heat.
The wavelengths of electromagnetic radiation extend from any long wavelength, withno upper limit no matter how long, continuously through all possible wavelengths, withno gaps, down to any short wavelength, with no lower limit no matter how short.
The University Corporation for Atomospheric Research's High Altitude Observatory reports, "The light or photons emitted from the Sun cover a broad spectrum from very long wavelengths such as radio to very short wavelengths such as xray." See the related link below for more information.
