We have fit the numerous high and low ion interstellar absorption-line profiles with theoretical models in order to determine the velocity and ion column densities of the sight-line gas clouds. Using ...
Cometary globules are a hard-to-detect subclass of so-called Bok globules, which are isolated and dense clouds of gas and dust surrounded by hot, ionized material. Despite their name, cometary ...
Some 350 years after a supernova, its shockwave reaches interstellar space and causes clouds of gas and dust to glow. Credit: NASA / ESA / CSA / STScI / Jacob Jencson (Caltech/IPAC) Scientists ...
Snapshots of colorful galaxies and planets show that the beauty of our universe knows no bounds, and recent images of glowing space gas and dust captured by NASA are no exception. The James Webb Space ...

Cepheus B, a molecular cloud located in our Milky Galaxy about 2,400 light years from the Earth, provides an excellent model to determine how stars are formed. NASA’s James Webb Space Telescope has ...
Discover how a giant interstellar cloud known as the solar nebula gave birth to our solar system and everything in it. The solar system as we know it began life as a vast, swirling cloud of gas and ...
These clouds tend to remain invisible ... this light pulse as it bounced off the surrounding gas and dust while traveling through the interstellar medium — a phenomenon known as a light ...
These bodies, hidden behind dense clouds of gas and dust, could represent a previously unknown type of interstellar object. The research, led by astrophysicist Takashi Shimonishi and his team, raises ...
These observations are allowing astronomers to map the true 3D structure of this interstellar dust and gas (known as the interstellar medium) for the first time. "We were pretty shocked to see ...
