Story summary

Observations from the James Webb Space Telescope suggest Earendel may be a star cluster, not a single star.
New spectral data shows Earendel's light resembles that of globular clusters, prompting re-evaluation of its classification.
Researchers call for further analysis to clarify Earendel's true nature.
Monitoring brightness changes and microlensing effects may reveal more about Earendel's structure.
The study stresses the need to explore multiple hypotheses for a comprehensive understanding of Earendel.

History

Historical Context

In 1929, Edwin Hubble's observations revealed the expanding universe, reshaping our understanding of cosmic structures. The Hubble Space Telescope, launched in 1990, later discovered Earendel, the most distant known star, emitting light from 900 million years after the Big Bang. Recent spectral data from both Hubble and the James Webb Space Telescope are prompting new insights into Earendel's nature and the early universe's formation.
