The finding
A team led by Marielle Eduardo reports detecting 27 trans-Neptunian objects using Webb's Near-Infrared Camera. The claim comes from the researchers' own paper abstract.
Two telescopes, one field
NASA describes observing the same patch of sky with Hubble in visible light and Webb in infrared. The coordinated observations provide different measurements of the distant objects.
What this report establishes
The discovery count is attributed to the research team; the observing method is described by NASA. These are primary accounts of the work, rather than independent replications of the result.
Combining visible and infrared observations offers a richer basis for studying these distant bodies than a discovery count alone. The value lies in what the measurements can establish, rather than in treating each detection as a new planet.
What remains uncertain
This brief checks the discovery claim and observing method against the research abstract and NASA's account. It does not independently validate the underlying data or resolve differences in size estimates between the documents.
What happens next
The full research paper is the place to examine the survey's detection limits and assumptions before drawing wider conclusions.
