Astrophysicists are mapping a vast, hidden structure in space that appears to guide matter and radiation along a kind of ...

Scientists have detected a narrow structure of hot plasma extending from the Local Hot Bubble surrounding the Sun toward ...

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 James ...

The intricate whorls and striations of dust that drift between the stars have just been revealed in stupefying detail. In new images from JWST, we're finally seeing exquisite details of the flow and ...

Southwest Research Institute's novel Compact Dual Ion Composition Experiment (CoDICE) instrument aboard NASA's Interstellar Mapping and Acceleration Probe (IMAP) spacecraft has successfully collected ...

The Sun warms the Earth, making it habitable for people and animals. But that’s not all it does, and it affects a much larger area of space. The heliosphere, the area of space influenced by the Sun, ...

Voyager 1 is 14.1 billion miles from Earth. It is the furthest man-made object from our planet, and it moves farther and farther away from us and into interstellar space every day. And still, more ...

This interstellar vagabond is only the third large interstellar visitor that we have ever discovered — an asteroid or comet that originated outside of our solar system and was discovered passing ...

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 ...

The heliosphere, a region dominated by the Sun's influence, extends far beyond the orbits of known planets and acts as a shield against cosmic rays, protecting the inner solar system. Voyager 1 and 2 ...

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 – a ...
