Deep in the vast expanse of the cosmos, a galaxy known as SDSS1335+0728 is stirring from its slumber. Situated 300 million light-years away from our planet, this celestial body first captured the interest of scientists in December 2019. The Zwicky Transient Facility at Palomar Observatory in California observed a significant increase in its brightness in optical wavelengths, sparking curiosity among researchers. Initially thought to be a typical AGN candidate, further analysis of archival data spanning two decades revealed that SDSS1335+0728 had been dormant until recently. Black holes can illuminate the darkness of space when they tear apart and consume stars, a captivating event known as a tidal disruption event. As the remnants of the devoured star swirl around the black hole, they generate intense radiation, resulting in a luminous display. While these occurrences are typically brief, lasting only a few days or months, SDSS1335+0728 defied expectations by remaining radiant for several years.
