Briefings

The Quanta Podcast episode discusses a 2025 discovery of two 'black hole stars'—objects resembling supermassive black holes but with different properties. Host Samir Patel interviews writer Charlie Wood about the findings, which were made using data from NASA's James Webb Space Telescope's NIRSpec integral field unit. The pitch of the sonification represents the velocity of hydrogen gas around these objects, allowing for the first direct mass measurement of a black hole from the early universe. The discovery challenges existing models of galaxy formation and black hole evolution.

Key points

• In spring 2025, two independent teams of astronomers simultaneously announced observations of a pair of celestial bodies resembling supermassive black holes but with unique characteristics.
• The discovery was made using data from NASA's James Webb Space Telescope's NIRSpec integral field unit, enabling the first direct mass measurement of a black hole from the first billion years of the universe.

Context and limitations

The podcast episode covers the 2025 discovery of 'black hole stars' using JWST data. Specific dates for the initial discovery announcement are not provided, and the exact nature of the new properties remains unconfirmed.
