James Webb Telescope Identifies New Class of Black Hole-Powered Stellar Object

Resumen

Astronomers using the James Webb Space Telescope have identified a previously unknown type of luminous object, dubbed a “black-hole star,” in which a massive black hole is enveloped by a dense gas cloud that emits intense radiation.

Astronomers analyzing images from the James Webb Space Telescope have reported the discovery of a new class of celestial object that combines features of stars and black holes. The objects, described as "black-hole stars," consist of a black hole surrounded entirely by a dense cloud of gas, rather than the flat accretion disks typically observed around such objects. Simulations suggest that a black hole roughly 100,000 times the mass of the Sun, encased in a gas envelope, can produce radiation bright enough to outshine its host galaxy.

The discovery was made while researchers were searching for distant galaxies and noted an unusually bright red point in the data. Subsequent modeling indicated that the intense luminosity arises from energy emitted by the black hole that passes through the surrounding gas, creating a visible source far brighter than ordinary stars.

These objects appear to be very old, observed only in the early universe when it was less than a billion years old. No comparable sources have been detected in more recent cosmic epochs, suggesting that the phenomenon may be linked to early stages of supermassive black-hole formation.

Scientists emphasize that the finding opens a new area of study, as the mechanisms behind these black-hole stars remain largely theoretical and will require further observation and modeling.
