NASA’s SPHEREx studies isolated brown dwarfs, the ‘failed stars’ wandering through space

Bookmark this story

Astronomers used NASA’s SPHEREx spacecraft to study brown dwarfs—objects that do not become stars and drift through space alone. The observations offer a closer look at these poorly understood objects and demonstrate the mission’s use in investigating the composition and properties of the universe.

Briefing

What Hype is tracking

  • The study uses SPHEREx to investigate brown dwarfs, extending the spacecraft’s role in astronomical research beyond its name recognition as a NASA mission.
  • Brown dwarfs are objects that do not become stars; better observations help researchers characterize a population of objects that can be difficult to study.
