What’s more, Webb used its Near Infrared Camera (NIRCam) instrument to observe glowing interstellar gas and dust illuminated ...

Now, thanks to the power of JWST to see dim, red light, we're finally gaining a fuller understanding of the interstellar medium's structure. What's even more incredible is that we can see changes in ...

Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest. What were they? Where did they come ...

These findings enable astronomers to study the full 3D structure of interstellar dust and gas (known as the interstellar medium) for the first time. In history, a gigantic star's core collapsed ...

That's less than 1% of a light-year. "We did not know that the interstellar medium had structures on that small of a scale, let alone that it was sheet-like," says Josh Peek, a member of the Webb ...

These sheet-like structures were not previously observed, challenging previous understanding of the interstellar medium. "We did not know that the interstellar medium had structures on that small ...

"We did not know that the interstellar medium had structures on that small of a scale, let alone that it was sheet-like," Peek said. The discovery was compared by scientists to a medical CT scan.

"We think every dense, dusty region that we see, and most of the ones we don't see, look like this on the inside — we just have never been able to look inside them before." ...

Astronomers from Turkey and Japan have performed optical observations of a recently discovered nearby supernova remnant known ...

For decades, scientists have marveled at the Local Hot Bubble—a vast, low-density region stretching roughly 1,000 light-years ...
