This is a segment of the "How Far Away Is It" 2017 review.
2017 was another very interesting year with a number of firsts. We detected our first asteroid from another star; a Type 1a Supernova companion survivor; a star collapse into a black hole without a supernova; a gravitationally lensed Type 1a Supernova; a non-elliptical early dead galaxy; colliding neutron stars; and visual confirmation of a gravitational wave.
