Illustration illustrating what two merging black holes look like similar to those detected by LIGO. The black holes rotate misaligned meaning they have different orientations relative to the general motion of the binary orbit. LIGO has found clues that the orbit of at least one black hole in the GW170104 system was previously undetected through its orbital motion before it merged with its partner.

This source may be a metal-poor blue giant, a good approximation of the first stars formed in the universe. Image: NASA/Swift/A. Simonnet, Sonoma State Univ.
