The researchers say they detected the presence of two new extrasolar planets (exoplanets) around a red dwarf star, Gliese 581, 20.5 light - years away in the constellation Libra, based on slight motions of the star. (scientificamerican.com)
There is slight motion blur in low light while walking, as the show shutter speed overwhelms the stabilization. (dxomark.com)
This technique is so sensitive that it could detect the very slight motion of the star approach and recede from the Earth at a speed of only 5 kilometers per hour, around walking pace. (seeker.com)
