A phase-locked loop with a jitter of 50 fs for astronomy applications
WebAstronomers have come up with two different techniques to estimate how far away any given star is. The first technique uses triangulation (a.k.a. parallax ). The Earth's orbit around the sun has a diameter of about 186 million miles (300 million kilometers). By looking at a star one day and then looking at it again 6 months later, an astronomer ...
