They best come out of the north about 2.30 am. They are rare indeed, but spectacular.

Some say they can be heard and our own Professor Colin Keay did considerable research into electrophonics.

Tel Aviv University in Israel commented on Professor Keay’s work.

“An Australian scientist Colin Keay suggested in the 1980s that perhaps the meteors generate radio waves.

“As with our home radio, we hear the news exactly at 8am no matter how far we are from the radio station.

“The reason is that the radio waves carrying the information travel at the speed of light to all of our homes.

“Then our radio has a method of converting the radio waves to sound waves (pressure waves) that vibrate the speaker, and our ear drums.

“So if the meteor sends out a radio wave together with the light we see, the radio waves and the light would both arrive at the same time at the observer.

“However, the radio waves then needs to be converted to sound waves. 

“Well, this can be done by simply vibrating any conducting object at the same frequencies of the radio waves.

“This is how speakers produce sound in your home radio system. 

“Metal fences, glasses, hair, plants, etc. can all be used as transducers to convert the radio waves to sound waves.

“This conversion of electromagnetic waves to acoustic/sound waves is known as electrophonics.”

So if you want to see these amazing large meteors, rise about 2.30am, stay in the dark to maintain dark adaptability 

and go outside and look up toward the north.

Then wait. If you are lucky you will see one of these brilliant messengers, left over remnants from the periodic Comet Swift-Tuttle.

Mankind has a most comprehensive history of exploration on Earth and now on our neighbouring planets.

The Moon and Mars at 400,000 and 54.6 million kilometres away respectively.

NASA has released a scale comparison of all the out-of-this-world rovers that have trundled over 

alien planets – our Moon and the Red Planet Mars.

This chart provides a comparison of the distances driven by various wheeled vehicles on the surface of Mars and Earth’s moon.

Of the vehicles shown, NASA’s Mars rovers Opportunity and Curiosity are still active and the totals listed are distances driven as of July 28, 2014.
