NASA's Fermi Mission Shows How Luck Favors the Prepared

The media elements below appear in the multimessenger astronomy video s accurate positions, together with other observations, showed that GRBs originate beyond our Milky Way galaxy.

Colored fields represent a component of the curvature of space-time. The outer red sheets correspond directly to the outgoing gravitational radiation detected by gravitational-wave observatories. The brighter yellow areas near the black holes do not correspond to physical structures but generally indicate where strong non-linear gravitational-field interactions are in play.Credit: NASA/C.
