Ancient First-Generation Star Discovered Outside Milky Way

France Info Paris 17d16d Impact 5

A group of students discovered a previously unknown star by observing water vapor in the sky. Students calculated the trajectory of a newly discovered star to determine its origin. Students have identified an extremely old star that originated outside the Milky Way galaxy. The star belongs to one of the earliest known generations of stars dating back to the beginning of the universe. Calculations of its trajectory confirm it did not form within our galaxy. This discovery is because the star contains elements that suggest it predates the heavier atoms found in younger stars like the Sun. Astronomers have identified a highly pure star named SDSS J07157334 located in the Voile Acté. Researchers observed the star using a telescope in Chile following a selection process of uncatalogued celestial bodies. This discovery follows the identification of approximately one million new stars annually.

The Sloan Digital Sky Survey (SDSS) program has been mapping the sky for 25 years to increase space accessibility. This project involves collaboration with 75 scientific institutions.

“c'est une découverte cosmique dont vous allez nous parler avec cette étoile inconnue révélée par de jeunes étudiants qui ont observé une base d'eau donnée du ciel”

France Info

“des étudiants en licence de l'université de Chicago l'an dernier qui ont examiné les bases de données pour chercher s'il y avait des astres inconnus.”

France Info

“d'où, les étudiants ont calculé sa trajectoire et déterminer quelle est originaire.”

France Info

“Cette nouvelle étoile, on ne va pas redire son nom complet, est trop vieille pour être d'ici. Elle ne peut pas être née dans notre galaxie.”

France Info

“Et les étudiants ont calculé sa trajectoire et déterminer quelle est originaire. Elle ne peut pas être née dans notre galaxie.”

France Info

“Et là surprise, la deuxième étoile de leur liste, joliment nommée SDSS J07157334 et qui se trouve dans notre voile acté, n'est pas du tout une étoile comme les autres.”

France Info

“Elle ne peut pas être née dans notre galaxie, elle vient donc forcément d'ailleurs et pour savoir d'où les étudiants ont calculé sa trajectoire et déterminé qu'elle est originaire du grand nuage de Magellan”

France Info

“une découverte cosmique... une des plus pures et des plus anciennes étoiles qui soient, qui datent du début de l'univers.”
