This animated graph displays the frequency and signal strength of gravitational waves using a simulated dataset of galactic ultracompact binaries. The colors on the graph indicate frequencies ranging from about 0.001 to 0.01 hertz, with lighter colors representing higher frequencies. The dashed curve shows the expected sensitivity limit of the LISA (Laser Interferometer Space Antenna) mission, which is currently being designed by the ESA (European Space Agency) in collaboration with NASA for launch in the 2030s.
