Astronomers will look at how the Sun and other stars vibrate like enormous musical instruments at an international conference in Sheffield next week (7-11 August, 2006) and will say that listening closely to the stars could be music to our ears.
Leading astronomer and astrophysicist Professor Don Kurtz will discuss how sound waves caused by natural vibrations of stars, produce eerie whistling, drumming, humming or rumbling sounds when their frequencies are raised to within human hearing ranges at an interactive, public lecture at Sheffield Hallam University called 'Songs of the Stars'.
This lecture is one of the highlights of the conference, which has been organised and hosted by the University of Sheffield and brings together experts from across Europe, the USA, Japan and Australia.
Professor Kurtz will demonstrate how Bach would sound if played by the stars, by combining different pitches from different stars to create a whole melody, projected by computer. He will also use helium, cymbals and bottles to recreate stellar sounds.
Professor Kurtz said:
"Stars have natural vibrations that are sound waves, just as musical instruments do. In the case of an instrument such as a horn, the cause of the vibrations is the musician blowing on the horn and buzzing his or her lips at a frequency that matches the natural vibrations of the horn. For the star, the vibrations start by changes in the passage of energy from the nuclear inferno in the heart of the star on its way to the surface, and escape into space.
"The ancient Greeks believed that the planets and stars were embedded in crystal spheres that hummed as they spun around the heavens, making what they called 'the music of the spheres', but it was not until the 1970s that astronomers discovered that the sun and other stars do actually 'sing'. We can't hear the sounds directly, but astronomers can detect them through asteroseismology - looking beneath the surfaces of the stars into their cores. We can see inside the Sun as clearly as you can see a foetus in the womb using ultrasound.
"Understanding the sounds of the stars is important for our understanding of the formation of the solar system and the Earth. We can even monitor dangerous 'active' regions on the far side of the Sun which might later send out coronal mass ejections and create geomagnetic storms, leading to power failure and radio disruption."
'Songs of the Stars' takes place on Tuesday 8 August, 2006 at 7pm, Pennine Lecture Theatre, City Campus, Sheffield Hallam University. Entry is free but by ticket only, available from Pat Brunskill on 0114 2254888 or email@example.com

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
