Astronomers have captured the first real-time glimpse of a massive black hole awakening from its sleep.

Previously unremarkable, SDSS1335+0728 began shining brighter than ever in late 2019, puzzling scientists.

The galaxy's luminosity has intensified for over four years, unlike typical celestial phenomena like supernova explosions.

SDSS1335+0728 is now emitting significantly more light across ultraviolet, optical, and infrared wavelengths, and recently started emitting X-rays.
