There’s nothing new under the sun. Hubble photo of black hole release date 2014.

The first direct observation of gravitational waves was made on 14 September 2015 and was announced by the
LIGO and
Virgo collaborations on 11 February 2016.
[3][4][5] Previously,
gravitational waves had only been inferred indirectly, via their effect on the timing of pulsars in binary star systems. The
waveform, detected by both LIGO observatories,
[6] matched the predictions of
general relativity[7][8][9] for a
gravitational wave emanating from the
inward spiral and
merger of a
pair of black holes of around 36 and 29
solar masses and the subsequent "ringdown" of the single resulting black hole.
[note 1] The signal was named GW150914 (from "Gravitational Wave" and the date of observation 2015-09-14).
[3][11][note 2] It was also the first observation of a binary black hole merger, demonstrating both the existence of binary
stellar-mass black hole systems and the fact that such mergers could occur within the current
age of the universe.
