NASA’s SPHEREx telescope has detected spectral signatures of water, carbon dioxide, carbon monoxide and methane in observations of 37 nearby brown dwarfs. The spectra also vary from object to object—including among brown dwarfs at similar temperatures—highlighting how much remains to be understood about their atmospheres.
What did SPHEREx find in brown dwarf atmospheres?
In a report published October 8, 2026, NASA and the Jet Propulsion Laboratory described an analysis of SPHEREx observations of 37 nearby brown dwarfs across a broad temperature range. Their spectra contain signatures of four molecules: water, carbon dioxide, carbon monoxide and methane. These are spectral clues to atmospheric chemistry, not direct images of individual molecules. NASA/JPL’s report describes the observed signatures and their variation.

The key finding is not that every object has an identical mix. Molecular features change across the temperature range, and brown dwarfs at similar temperatures can still have distinct spectra. As study coauthor and IPAC scientist J. Davy Kirkpatrick put it, “We’re seeing the signatures of these molecules and how they change from object to object across the entire temperature regime.”

A brown dwarf forms from a collapsing cloud of gas, much as a star does, but it does not have enough mass to sustain hydrogen fusion in its core. NASA describes brown dwarfs as dimly glowing, warm gas objects that share characteristics with giant planets such as Jupiter and Saturn. Their atmospheres therefore offer a way to study objects between the familiar categories of stars and planets. NASA’s brown dwarf overview explains the distinction.

How does SPHEREx study brown dwarfs?
SPHEREx is a NASA infrared space telescope launched on March 11, 2025, and managed by NASA’s Jet Propulsion Laboratory. It measures brightness in 102 different colors, producing spectral information that helps researchers identify molecular signatures. Its near-infrared coverage spans 0.75–5.0 micrometers, according to IPAC’s mission overview.
Some of those wavelengths are difficult or impossible to measure from the ground because Earth’s atmosphere absorbs them. SPHEREx’s main mission is to map the sky; its broad observations also create opportunities to study brown dwarfs. IPAC describes the nominal mission plan as four maps of the entire sky over 25 months. Those mission-wide figures describe the survey plan, not the number of brown dwarfs in this particular analysis.

Why do brown dwarfs have different spectra?
The spectra reflect differences in atmospheric conditions and chemistry, but the reported analysis does not establish a complete weather model for each object. NASA’s account describes some brown dwarfs in a cloudy transition phase: clouds thin, while methane-rich atmospheric features become more apparent. This pattern helps explain why spectra can change across objects, but it does not resolve every cause of their diversity.
The findings also present a challenge for atmospheric models. Lead author Zafar Rustamkulov, an IPAC scientist, said: “The state-of-the-art models are capturing the general chemical trend, but when it comes to these cloudy transitions, the models are struggling to match the data.” A useful comparison is therefore not just which molecules appear, but how well model predictions reproduce the observed spectral features, particularly around cloudy transitions.

Rustamkulov also noted that objects at similar temperatures can have markedly different spectra: “No two brown dwarfs are alike. Even at the same temperature, their spectra look quite distinct.” That diversity means temperature alone does not account for the observed range. The 37 objects are the sample discussed in NASA’s report; the team is analyzing thousands more, so the reported results are not a census of all known brown dwarfs.
