Brown Dwarfs: The Celestial Objects That Are Neither Stars Nor Planets
By
SETI Institute
Summary
This article discusses brown dwarfs — celestial objects that blur the line between the lowest-mass stars and the largest gas giant planets. Brown dwarfs form like stars from collapsing gas and dust clouds but lack sufficient mass to sustain hydrogen fusion, causing them to cool and fade over time. The content appears to be drawn from a SETI Institute discussion exploring these galactic oddballs and the challenges astronomers face in studying them.

· 3 pulledThese celestial bodies are known as brown dwarfs, often referred to as galactic oddballs because they form out of collapsing clouds of gas and dust like stars, but never accumulate enough mass to ignite the hydrogen fusion that powers a typical star.
Lacking an internal energy source, brown dwarfs spend their lives cooling and fading into obscurity.
Astronomers have long struggled to map the objects that occupy the dim, ambiguous boundary between the lowest-mass stars and the largest gas giant planets.
