The James Webb space telescope has detected new evidence of some of the universe's biggest stars, the largest with a mass 300 times our Sun.
James Webb has peered deep into our universe and uncovered evidence of “celestial monster” stars, the universe’s biggest stars. The astronomers behind the discovery say that these monster stars are brighter than millions of Suns in the early universe. The scientists also say that the largest celestial monsters among them have a mass 300 times that of our Sun.
These supermassive stars are described in a new study. The largest star discovered is believed to have a mass of 5,000 to 10,000 Suns.

These elements include aluminum, which requires a temperature of up to 70 million degrees Celsius to produce. However, these stars are often only 15 to 20 million degrees Celsius. As such, this composition has left astronomers baffled.
The possible explanation behind these old stars, then, is collisions in the tightly packed globular clusters that some of the universe’s oldest stars call home.
