Potential first traces of the universe’s earliest stars

Astronomers may have discovered the ancient chemical remains of the first stars to light up the Universe. Using an innovative analysis of a distant quasar observed by the 8.1-meter Gemini North telescope on Hawai‘i, operated by NSF’s NOIRLab, the scientists found an unusual ratio of elements that, they argue, could only come from the debris …

Astronomers discover traces of ‘super-supernovas’ that destroyed earliest stars

Astronomers may have found the chemical traces of the one of earliest stars — born when the universe was just 100 million years old — that exploded in a “super-supernova.” These first-generation stars, known as Population III stars, ended their lives in titanic supernova explosions that seeded the universe with chemical elements the stars had …

Wide view of early universe hints at galaxy among earliest ever detected

Scientists with the CEERS Collaboration have identified an object—dubbed Maisie’s galaxy in honor of project head Steven Finkelstein’s daughter—that may be one of the earliest galaxies ever observed. If its estimated redshift of 14 is confirmed with future observations, that would mean we’re seeing it as it was just 290 million years after the Big …

Scientists find the secret to birth of earliest black holes in the Cosmos

Scientists find the secret to birth of earliest black holes in the Cosmos

It takes a long time to grow a supermassive black hole, even if it eats voraciously. So just how supermassive black holes billions of times heavier than the Sun formed within the first billion years of the universe has been an enduring puzzle. But new work by an international team of cosmologists suggests an answer: …
