GW150914 remnant is an epic black hole. It lies about 1.34×10^9 light-years from Earth and sits in the constellation Vol.
We know about it because it shook spacetime: the merger that formed it stretched and squeezed the Earth by less than the width of a proton, and detectors on the ground recorded the ripple passing through.
Look for GW150914 remnant in the constellation Vol.
Like any astronomical target, GW150914 remnant is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
GW150914 remnant scores 62 points on Spacedle's rarity scale, which places it in the epic tier. Another 16 points would lift it into a rarer tier.
That score comes from 5 science badges — Black hole, Outside our galaxy entirely, Stellar-mass black hole, Dormant (nothing left to eat) and Heard as a gravitational wave — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
