Four distant galaxies in SMACS 0723. Analysis of the very first image from the James Webb Space Telescope shows that the infrared telescope reveals details of galaxies from the time when the universe was only about 1 billion years old. Left: the first image with four galaxies highlighted. On the right, the four galaxies each …

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 the earliest stars

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

NASA’s Artemis 1 moon rocket will be grounded for at least four more days. NASA had been eyeing Sept. 23 or Sept. 27 for the launch of Artemis 1, which will use a Space Launch System (SLS) megarocket to send an Orion capsule on an uncrewed test flight to lunar orbit. But the agency announced …

7 million years ago, our earliest relatives took their first steps on 2 feet

Leave a Comment / Science / By samypauls367

The oldest known human-like species likely walked on two legs as far back as 7 million years ago, a new study finds, and the discovery sheds light on what first set humans apart from our ape relatives. Researchers analyzed a thigh bone (femur) and a pair of forearm bones (ulnae) from Sahelanthropus tchadensiswhich may be …

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

Leave a Comment / Science / By samypauls367

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 …
