An international scientific team led by Pennsylvania State University in the USA used JWST data to reveal that the three red-bright objects they discovered in 2022 and thought could be galaxies actually contained ancient star features.

Research leader Bingie Wang, an academic at Pennsylvania State University, said the bright objects bore the signature of the “oldest stars” and added, “When their brightness and distances were investigated, we concluded that they were ancient stars that were hundreds of millions of years old.”

Researchers shared the information that traces of supermassive black holes were also found in these objects.

Meanwhile, it was stated that the bright objects discovered were formed 600-800 million years after the Big Bang.

The research was published in the Astrophysical Journal Letters.
