Scientists Explore Black Hole Star Explanation for Little Red Dots

Astronomers have identified a new class of cosmic object called a black hole star, written as BH”, in a study published in Nature on 12 August 2026. The object MoM-BH”-1 was detected by the James Webb Space Telescope during the Mirage or Miracle of the MoM survey and existed less than 660 million years after the Big Bang.

Black Hole Star Concept

A black hole star is a proposed early-universe object with a central black hole surrounded by a dense envelope of hydrogen and helium gas. In this model, the black hole powers the object in a way that differs from ordinary stars, which generate energy through nuclear fusion in their cores.

MoM-BH”-1 Discovery

MoM-BH”-1 is described as the most distant black hole star found so far. It is roughly the size of the Solar System and contains a central black hole about 100,000 times the mass of the Sun. The object appears to exist without a surrounding galaxy.

Little Red Dots and Spectral Features

Little Red Dots are compact, red, high-redshift objects observed in the early universe. MoM-BH*-1 shows a deep Balmer break, which is a sharp drop in brightness at specific wavelengths linked to hydrogen absorption. Measurements also indicate an energy output about 100 billion times greater than that of any known star.

Important Facts for Exams

• The James Webb Space Telescope was launched in 2021 and is used for infrared astronomy.
• The Big Bang occurred about 13.8 billion years ago, and objects seen 660 million years after it belong to the cosmic dawn era.
• The Balmer series is associated with hydrogen and is used in stellar spectroscopy.
• The Astrophysical Journal and Nature are major peer-reviewed scientific journals.

A study published in The Astrophysical Journal on 10 June 2026 examined the Little Red Dot GLIMPSE-17775 and supported the black hole star model using deep spectral data. On 16 March 2026, alternative models were also presented for some Little Red Dots, including supermassive stars and forming globular clusters.
