JWST’s sharp infrared eyes is revealing stunning new details that have been invisible to previous observatories.
, Lee and her colleagues selected 19 galaxies that, if observed with the telescope, they thought could reveal new details of the life cycles of stars . These galaxies are relatively close, within 65 million light-years of the Milky Way, and all have different types of spiral structures. The team had observed the galaxies with many observatories, but parts of the galaxies had always looked flat and featureless.
Astronomers are using JWST to study several galaxies with different types of spiral structures to compare how their stars form. NGC 1365 has a bright bar in its core that connects its spiral arms. JWST detected glowing dust in this galaxy’s center that had been obscured in previous observations.In the new images, the galaxies’ faces are pockmarked by dark voids amid glowing filaments of gas and dust.
