It may be one of the most iconic sights in the night sky, but astronomers have never seen the Helix Nebula like this before.

“The knowledge of these will ultimately help us understand the formation of the first stars and planets and how our own Milky Way came into being.”
…
Some newly found stars in a small galaxy called Sextans A are forming without some of the usual “ingredients,” raising questions about how the early universe evolved.
…
There may not be as nearly as many small galaxies in the early universe as astronomers predict there should be, which has big implications for the story of how our universe grew up.
…
“These nine objects are special.”
Both NASA’s James Webb Space Telescope and Chandra X-ray Observatory caught these two galaxies in a close embrace.
…
The galaxy cluster appears hotter and more mature than it should for its young age, challenging what we think we know about how these cities of galaxies form.

After combing through NASA’s James Webb Space Telescope’s archive of sweeping extragalactic cosmic fields, a small team of astronomers at the University of Missouri says they have identified a sample of galaxies that have a previously unseen combination of features. Principal investigator Haojing Yan compares the discovery to an infamous oddball in another branch of […]
Using NASA’s James Webb Space Telescope, astronomers have spotted two rare kinds of dust in the dwarf galaxy Sextans A, one of the most chemically primitive galaxies near the Milky Way. The finding of metallic iron dust and silicon carbide (SiC) produced by aging stars, along with tiny clumps of carbon-based molecules, shows that even […]
A team using NASA’s Hubble Space Telescope has uncovered a new type of astronomical object — a starless, gas-rich, dark-matter cloud considered a “relic” or remnant of early galaxy formation. Nicknamed “Cloud-9,” this is the first confirmed detection of such an object in the universe — a finding that furthers the understanding of galaxy formation, […]
