Since becoming operational last year, the James Webb Space Telescope has made groundbreaking observations involving some of the universe's earliest galaxies. One might call them galactic infants. ...
Significant amounts of nickel observed in galaxies only two-to-three billion years after the Big Bang.
<p>Galaxies that formed just 2 to 3 billion years after the Big Bang are unusually hot and glow with light from surprising elements, like nickel, according to new work led by Carnegie’s Gwen Rudie and Northwestern University’s Allison Strom. Studying “teenage galaxies” from the ancient universe can teach scientists about how these massive systems of stars mature and evolve.</p>
