article_snippet: Of course, as space is a vacuum it is impossible to hear sound in space, but the discovery reveals a new way that fluids can interact to produce a sound - one with an extremely high frequency.
article_snippet: A team of scientists that included York University fired an ultra-intense laser on fluids in a laboratory.
article_snippet: When A team of scientists that included York University did this, the plasma in the fluid produced a sound wave.
article_snippet: To make the finding, A team of scientists that included York University studied fluids in motion in a laboratory and found that, when plasma is hit with an ultra-intense laser, plasma produces some strange effects.
article_snippet: Using a method not too dissimilar to how a speed camera works, A team of scientists that included York University were able to observe how the fluid moves at the point it is struck.
article_snippet: A trillionth of a second after the laser hits, plasma was found to flow quickly from areas of high density to low density.
article_snippet: It was initially hard to determine the origin of the acoustic signals, but our model produced results that compared favourably with the wavelength shifts observed in the experiment,’ added Dr Alex Robinson, from the Plasma Physics Group at the Science and Technology Facilities Council’s Central Laser Facility in Oxfordshire.
article_snippet: This showed that we had discovered a new way of generating sound from fluid flows.
