Stars don't form out of nothing, but tracking the gas and dust that do eventually form stars is hard. They float around the galaxy at almost absolute zero, emitting essentially no light, and generally ...

The Milky Way's interstellar medium—that is, the dust and gas that threads between our galaxy's billions of stars—is an abundant yet elusive material. That means the latest image from NASA's ...

A team of astronomers has uncovered an unexpectedly complex and dynamic filamentary network within a very-high-velocity cloud ...

Priscilla Diane Chapman Frisch, a University of Chicago Research Professor in Astronomy and Astrophysics and a world-leading scientist on the heliosphere and the local interstellar medium, died on ...

While astronomers expect many supernova remnants remain to be discovered, the fact that Teleios was spotted at all “is pure luck,” Filipović says. Had it been located closer to the galactic plane, ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), researchers from the Shanghai Astronomical ...

Scientists have developed a new computer model to explore the the interstellar medium, in turn generating stunning images that resemble abstract works of art.

Astronomers are tracking a newly spotted comet hailing from parts unknown, only the third time such an interstellar object ...

A groundbreaking new survey from China’s LHAASO observatory has unveiled powerful ultrahigh-energy gamma-ray emissions across ...

Research on heliospheric physics and interstellar medium dynamics has advanced our understanding of the complex interaction between the solar wind and the interstellar environment. The heliosphere ...

In the case of Voyager 1, it’s been picking up the faint hum of plasma waves in the interstellar medium. The plasma that Voyager 1 is encountering was produced by our Sun, the researchers say.
