Our radio waves, we believe, can be detected 200 lightyears distant from Earth, according to our calculations. Our own galaxy, the Milky Way, has a radius of 53 000 lightyears, making it the largest in the universe.

How far can a radio signal travel in space?
Radio waves are similar to other types of E&M radiation in that they may travel indefinitely far in a vacuum at the speed of c. c = 2.998×108 meters per second (c = 2.998×108). Photons can have a frequency that corresponds to the frequency of radio waves.
Can radio signals travel through space?
Electromagnetic waves are distinct from mechanical waves in that they do not propagate via a medium to achieve their destination. This indicates that electromagnetic waves may travel not just through air and solid things, but also through space itself, which is considered to be a vacuum. This demonstrated that radio waves were in fact a kind of light!
How long does it take a radio signal to travel from Earth to Mars?
Depending on the planets’ positions, it can take anywhere from 5 to 20 minutes for a radio transmission to cross the distance between Mars and Earth.
How long does it take for a radio signal to reach Pluto?
You might wonder how long it takes for the radio signal to reach the New Horizons spacecraft to Pluto, which is over 3 billion miles (4.6 billion kilometers) away from Earth. The answer is: it depends. It will take around 4.5 hours!
How long does it take for a radio signal to go from the Earth to the Moon?
Radio waves propagate at the speed of light c, which is precisely 299,792,458 meters per second in vacuum. The time it takes to get to and from the Moon varies between 2.4 and 2.7 seconds, with an average of 2.56 seconds (the average distance from Earth to the Moon is 384,400 km).
How long does it take for a radio signal to reach Voyager 1?
The spacecraft collects information about their surrounding environment in real time and transmits it back to Earth through radio waves to keep them connected. It takes around 19 hours for data from Voyager 1 to reach Earth, and approximately 16 hours for signals from Voyager 2. It takes the rovers on Mars an average of 20 minutes to contact Earth, as a point of comparison.
How close can you get to the sun without dying?
According to the International Space Station, the sun is around 93 million miles away from Earth. If we imagine this distance as equivalent to that of a football field, a person starting at one end zone might travel approximately 95 yards before burning up. Having said that, an astronaut thus near to the sun is in a completely unnatural posture.
How fast do radio waves move?
Radio waves move at the speed of light, which is roughly 186,000 miles per second, which is approximately 186,000 miles per second.
