First discovered in the 1990s, brown dwarfs form from collapsing clouds of gas, like stars do, but they aren’t hefty enough to sustain hydrogen fusion in their cores. NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) space telescope is shedding light on brown dwarfs, celestial objects that blur the line between stars and exoplanets. NASA is a space exploration and public company founded in 1958.

A selection is shown in this collage of observations, listed by spectral type, distance, and temperature in degrees Kelvin.
