Hubble into music.

Back to the space telescope!

I cannot stop engaging in Hubble stories and republishing them in this place.

The latest is an account, published here, of how scientists turned an image of a galaxy into music! Or rather added music to the video.

Here it is!

Cool! A Hubble photo translated to music

Posted by in | May 10, 2020

There’s no sound in space. But – working with NASA – musicians and scientists turned a Hubble Space Telescope image of a galaxy cluster into music.

We stumbled on this video via a May 3, 2020, re-post at ScienceAlert. Matt Russo and Andrew Santaguida of System Sounds in Toronto – which calls itself “a sci-art outreach project” – created the video. It’s part of NASA’s Astrophysics Visualizations series. NASA explained the video this way:

Space becomes sonified in this visualization of a cluster of galaxies imaged by NASA’s Hubble Space Telescope. Time flows left to right, and the frequency of sound changes from bottom to top, ranging from 30 to 1,000 hertz. Objects near the bottom of the image produce lower notes, while those near the top produce higher ones. Most of the visible specks are galaxies housing countless stars. A few individual stars shine brightly in the foreground. Stars and compact galaxies create short, clear tones, while sprawling spiral galaxies emit longer notes that change pitch. The higher density of galaxies near the center of the image – the heart of this galaxy cluster, known as RXC J0142.9+4438 – results in a swell of mid-range tones halfway through the video. Hubble’s Advanced Camera for Surveys and Wide Field Camera 3 acquired this image on August 13, 2018.

Cool!

Here’s the original Hubble image of galaxy cluster RXC J0142.9+4438, later “sonified” by Russo and Santaguida. NASA wrote: “Galaxies abound in this spectacular Hubble image; spiral arms swirl in all colors and orientations, and fuzzy ellipticals can be seen speckled across the frame as softly glowing smudges on the sky. Each visible speck of a galaxy is home to countless stars. A few stars closer to home shine brightly in the foreground, while a massive galaxy cluster nestles at the very center of the image; an immense collection of maybe thousands of galaxies, all held together by the relentless force of gravity.” Read more about this image, which is via ESA/ Hubble & NASA, RELICS.

Bottom line: Musicians and scientists turned a Hubble Space Telescope image – of galaxy cluster RXC J0142.9+4438 – into music.

That is so lovely.

It’s only just over half a minute long but is still precious!

And I learnt a new word: sonification!

Your call is so, so important to us!

A delightful trawl by Neil Kelly through the call centre industry.

Are there any more annoying phrases in the English language than “your call is important to us“, or “we are experiencing particularly high call volumes“?

In 2007 companies worldwide spent some $280 billion on outsourced call-centre services, according to NASSCOM, a call-centre trade group in Delhi. Much of India’s call-centre industry, which employs roughly 300,000 agents, is located outside the ring road that encircles Bangalore, in a string of smart new business parks with tidy lawns and private security. Were it not for the stray dogs, a visitor could be forgiven for mistaking the area for Silicon Valley.

Meanwhile in Australia …

Meanwhile …… back in Wales in the United Kingdom … listen to this call centre handling a complaint from an ASDA customer – listen right to the end!

Thanks to David from neatorama.com I was able to put together a medley of hold music and without resorting to The Four Seasons!  Hope to have The Top Twenty Hold Music Songs out in time for Christmas.
