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, ...

A baby sunlike star blowing a bubble of hot gas called an “astrosphere” was captured for the first time by NASA’s Chandra X-ray Observatory ...

IMAP will examine the edge of this bubble and observe how it interacts with the space. NASA launched the Interstellar Mapping and Acceleration Probe (IMAP) spacecraft from Kennedy Space Center in ...

Scientists have found a protective bubble around a young star, HD 61005. This astrosphere, similar to our Sun's heliosphere, shields planets from harmful cosmic rays. The discovery helps understand ...

A new study funded by the National Aeronautics and Space Administration (NASA) has revealed that the heliosphere of the sun is dominated by two giant jets of material that blasts over the star's south ...

A new study indicates that a bow shock (a dynamic boundary between sun’s heliosphere and the interstellar medium) is highly likely. These findings challenge recent predictions that no such bow shock ...

(CNN) — Surrounding our solar system is a natural and enigmatic cosmic shield called the heliosphere — and a new mission has launched to help astronomers better understand it. Created by the solar ...
