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

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

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 ...

The universe is different. “In the interstellar medium,” says Schilke, “argon-36 is by far the most abundant, and we were just too stupid to realize it.” ...

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.

The interstellar medium (or ISM) is the name astronomers give to the tenuous gas and dust that pervade interstellar space. Whilst the ISM refers to the matter (interstellar matter, also ...

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 ...

We can probe the ionized interstellar medium through imaging and timing observations of compact radio sources. As the radio waves pass through the interstellar medium, they are distorted and delayed ...

The solar system drifts inside an immense, low-density cavity known as the Local Hot Bubble (LHB). This region, spanning at least 1,000 light-years, radiates X-rays due to its searing million ...

Our peer-reviewed reports present the evidence-based consensus of committees of experts. Published proceedings record the presentations and discussions that take place at hundreds of conferences, ...

An interstellar probe could measure plasma and magnetic fields in the interstellar medium and scan the heliosphere. Skip to content Introducing the all-new Astronomy.com Forum!

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 ...
