A team of researchers examined data taken by NASA's Infrared Astronomical Satellite (IRAS) in 1983 and identified hundreds of potential black holes.
Notes on verification
Confirmed by the peer-reviewed paper (Boorman et al. 2025, ApJ) and multiple independent outlets (NASA/JPL, NuSTAR/Caltech, Space.com, Live Science), though most reporting traces back to a single press release and study.
