Stars don't form out of nothing, but tracking the gas and dust that do eventually form stars is hard. They float around the ...

Decades ago, astronomers estimated that “ordinary” matter (basically everything that isn’t dark matter or dark energy) makes up 5% of the universe. There was just one problem—they had no idea where ...

A team of astronomers, led by researchers from the Shanghai Astronomical Observatory (SHAO), has uncovered an unexpected and intricate network of tangled, supersonic filaments within a ...

Stars of all ages and masses emit electromagnetic energy in different ways, and these emissions attract the attention of ...

Harvard astronomer Avi Loeb suggests that if interstellar object 3I/ATLAS isn't a comet, nor an asteroid, it may have been ...

Step into the vast and mysterious depths of interstellar space with this breathtaking 4K journey through the universe. This video takes you beyond the boundaries of our solar system, offering a ...

The interstellar medium in our Milky Way galaxy is magnetic, can be compressed, and is turbulent. It affects important processes like star formation, cosmic-ray movement, and materials mixing in ...

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, ...

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.

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 ...

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 ...

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