Astronomers found an interstellar "tunnel" - a cosmic channel that connects our solar system to distant stars, according to a ...

Interstellar comet 3I/ATLAS shocks scientists with thruster-like jets and a vivid blue glow, fuelling debate over its ...

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 ...

Inside its boundary, the flux of galactic cosmic rays is reduced, which decelerates CO-to-CO₂ conversion. Outside, in the interstellar medium, there is no such protection. Researches on the shape and ...

Observations were maintained using imagery from solar imagers on the STEREO-A, SOHO, and GOES-19 missions near the Sun.

Once upon a time, the core of a massive star collapsed, creating a shockwave that blasted outward, ripping the star apart as it went. When the shockwave reached the star’s surface, it punched through, ...

An interstellar object roughly the size of Manhattan has captured scientists’ attention — and one prominent Harvard ...

I/ATLAS was recorded by several objects as it made its close pass by the sun this week which resulted in the jarring measurements.

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 ...

Harvard astrophysicist Avi Loeb proposes that interstellar object 3I/ATLAS could be made of antimatter—"the most efficient fuel"—while NASA scientists remain sceptical.

A supernova remnant, Cassiopeia A (Cas A), resulting from a stellar explosion approximately 11,000 years ago, is being studied using the James Webb Space Telescope (JWST). JWST observations focus on a ...
