See the 19 spiral galaxies captured by NASA “on the smallest scales ever observed” behind the Milky Way
NASA has captured a “treasure trove” of stunning new images showing 19 spiral galaxiesThe European Space Agency reported on Monday. The agency said that the images reveal “stars, gases and dust on the smallest scales that have been observed outside our Milky Way galaxy.”
According to the agency, researchers are analyzing the new images to find out how these galaxies originated. NASA says these images were taken as part of the Physics at High Resolution in Nearby Galaxies (PHANGS) program, and show millions of stars that “shine in shades of blue.” NASA said it also reveals “glow dust” and stars that are still growing.
Eric Rosolowski, a physics professor at the University of Alberta in Edmonton, Canada, said some of the “newest and most massive stars in galaxies” can be found in the images. PHANGS researchers have also released what NASA says is the largest catalog ever of nearly 100,000 star clusters, a list that Rozolovsky says allows for analysis that is “much larger than anything our team can handle.”
but this is not all. The images of the galaxies also show “large spherical shells” that may have formed as a result of exploding stars, as well as supermassive black holes, which can be seen as galaxy cores with pink and red bumps, the researchers said.
The galaxy images are “extraordinary,” said Janice Lee, a strategic initiatives project scientist at the Space Telescope Science Institute in Baltimore, Maryland.
“It’s amazing even for researchers who have studied these same galaxies for decades,” Lee said. “The bubbles and filaments were resolved to the smallest scales ever observed, and tell a story about the star formation cycle.”
