Astronomers mapping interstellar dust in three dimensions have identified a giant spherical void in the Milky Way, roughly ...

NASA’s Chandra X-ray Observatory captured a protective astrosphere around HD 61005, providing direct observation of a Sun-like star’s wind interacting with surrounding interstellar material ...

An instrument built by the University of Colorado Boulder will soon launch on a NASA space mission where it will aim to collect interstellar dust particles hurtling through space at an average of 16 ...

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 ...

Interstellar dust extinction as a research area investigates the wavelength-dependent attenuation of starlight and other electromagnetic radiation by dust grains in the interstellar medium, with ...

Molecules containing noble gases shouldn’t exist. By definition, these chemical elements — helium, neon, argon, krypton, xenon and radon — are the party poopers of the periodic table, huddling in the ...

This chapter summarizes the community’s basic understanding of the physics of the outer heliosphere, focusing on the influence exerted on the solar wind by the interstellar medium (Box 2.1). In ...
