We've been surrounded by images of space our whole lives, from the speculative images of science fiction to the inspirational visions of artists to the increasingly beautiful pictures made possible by complex technologies. But whilst we have an overwhelmingly vivid visual understanding of space, we have no sense of what space sounds like.

Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky. And just like the signals that we send and receive here on Earth, we can convert these transmissions into sound using simple analog techniques.

The study of celestial phenomena at radio wavelengths, radio astronomy came into being after the accidental discovery of cosmic radiation by radio engineer Karl Jansky in 1933.

Solar bursts typically last from half a minute to a couple of minutes and often sound like a rapid hissing noise followed by a gradual decrease back to the original audio level.

It used to cost money to disclose and distribute information. In the digital age it costs money not to.

Given the trendlines of digital publishing, where more and more large platforms are profiting from, and controlling, the works of individuals, I can't stress enough: Put your taproot in the independent web. Use the platforms for free distribution (they're using you for free content, after all). And make sure you link back to your own domain.

The bottom line is there are lots of problems that were not created by government. The biggest one is loss of middle class incomes, loss of good-paying jobs which was created by technology and globalization. Above all, when you can move a job to China or India, it reduces wages.

I think social media has reinvigorated people's enthusiasm to be active and to engage.
