Astronomers Detect Nickel and Other Unexpected Elements in Early Star-Forming Galaxies
<p>In the Universe’s youth, many galaxies experienced a period of intense star formation.</p>
<p>Today, some galaxies, such as our own Milky Way, still form new stars, albeit not as rapidly. Other galaxies have stopped forming stars altogether.</p>
<p>This new work can help astronomers understand the reasons behind these different trajectories.</p>
<p>“We’re trying to understand how galaxies grew and changed over the 14 billion years of cosmic history,” said Dr. Allison Strom, an astronomer at Northwestern University.</p>
<p>“Using the NASA/ESA/CSA James Webb Space Telescope, our program targets ‘teenage’ galaxies when they were going through a messy time of growth spurts and change.”</p>
