The Secrets of the Universe | Webb Spots Bizarre Stars At The Edge of Time That Will Break Your Brain @TheSecretsoftheUniverse | Uploaded August 2023 | Updated October 2024, 4 days ago.
The James Webb Space Telescope has made another exciting discovery. A study has unveiled evidence of the first stars, astonishingly 1000 to 100000 times more massive than the Sun. For context, the most massive star we know of is only 250 times the Sun's mass.
These colossal stars boast core temperatures reaching a staggering 75 million degrees Celsius, which is five times hotter than the Sun’s. While peering at the edge of time in the early universe, JWST discovered indications of these gigantic first stars in one of the most distant galaxies known to us. This remarkable study holds the potential to illuminate the very beginnings of the cosmos and unveil the last unexplored era in the captivating history of cosmology.
But how did astronomers make this exciting discovery? How did they determine the mass of these extraordinary stars? Finally, and most importantly, how will this discovery help us understand what happened when the universe was in its cradle?
The 70th episode of the Sunday Discovery Series answers all these questions in detail.
RESEARCH PAPERS:
N-enhancement in GN-z11: First evidence for supermassive stars
nucleosynthesis in proto-globular clusters-like conditions
at high redshift? - Charbonnel et al. - bit.ly/457VZyO
Supermassive Dark Star candidates seen by JWST, Ilie et al. -bit.ly/3s99PT2
