The Vostro V131 is perfect for everyday office operations like document editing, presentations and email, and also provides stellar collaboration options including a full HD camera, SRS Premium Voice Pro, digital array mics and built-in Skype.
The infra-red light from dust heated by a star has a much longer wavelength ie, is cooler than most of the light from the star itself, so a camera tuned to the right wavelength can pick out a dust disc without being totally blinded by the stellar glare.
