Astronomers split over whether Webb's 'little red dots' are black hole stars

The short version

• Two astronomy teams proposed that Webb's little red dots are a new object they call a 'black hole star,' a hydrogen lump hiding a black hole.[Wired]
• Other astronomers, including Roberto Maiolino and Piero Madau, argue the dots are conventional black holes whose redness comes mainly from viewing angle.[Wired]
• Researchers describe the field as polarized, and at least one skeptic calls the data compelling while doubting the interpretation.[Wired]
• Interpretation remains unresolved, and the disagreement has sparked a flurry of follow-up research.[Wired]

Key facts

• Astronomers began calling bright, compact red objects detected by Webb 'little red dots' in 2023.[Wired]
• In spring 2025, two teams announced observations of a pair of little red dots unlike any object previously seen.[Wired]
• The teams led by Anna de Graaff and Rohan Naidu, along with Vadim Rusakov's team, posted their findings on March 20, 2025.[Wired]
• Two teams proposed a new object called a 'black hole star,' described as a lump of hydrogen hiding a black hole in its core.[Wired]
• Roberto Maiolino and Piero Madau argue that the redness of the dots comes mainly from the angle at which they are viewed.[Wired]
• Dale Kocevski recalled that a discussion of the dots at an April 2026 conference in Aspen, Colorado, turned into argument.[Wired]
