In space, no one can hear you scream — but no one can hear anything in the vacuum of space, thanks to a lack of molecules to carry sound waves. The sun is out there screaming up a storm, for example, and nobody hears a peep.
Until now, that is. The video below contains spooky sounds from the March 7 solar storm, created by sun particles smashing into NASA's Messenger and SOHO spacecraft. Using a process called "sonification," University of Michigan graduate student Robert Alexander took these visual data — the wavelength and amplitude of light — and converted them into the pitch and volume of sound. The results are eerie:
To compare those sounds with sights from the same storm, check out two more videos below — one shows the storm itself on March 6, and the other shows its effects on Earth three days later, in the form of aurora australis over New Zealand:[/skipwords]
