How spacecraft beyond the solar system navigate the stars

Подробнее о видео

Images beamed back from the New Horizons spacecraft, which has left the solar system, have enabled the first test of interstellar navigation. By measuring the distance between two stars that it snapped images of, astronomers have been able to pinpoint its location in the galaxy. And in other interstellar news, we also just spotted an object hurtling towards our solar system. Recently named ‘Atlas’, this object will be whizzing by in October, close enough for us to study.

Hosted by Rowan Hooper and Penny Sarchet, with guest Alex Wilkins.
