A NASA probe has started its mission to map the heliosphere, which is a huge protective bubble around the solar system that was created by the sun, the space agency announced on Monday.

NASA’s IMAP spacecraft studies charged particles, energetic neutral atoms, and magnetic fields at the heliosphere’s boundaries, providing real-time space weather data for Earth and spacecraft.

A NASA spacecraft has just reached its permanent observation point to begin a mission unlike any before. Known as IMAP, the ...

NASA’s Transiting Exoplanet Survey Satellite has once again surprised astronomers by tracking interstellar comet 3I/ATLAS, a ...

NASA’s newly launched IMAP mission is set to tell us more about the boundary between our Solar System and interstellar space ...

NASA's most distant spacecraft had a critical thruster problem far from home. Fixing it required a long-distance call to overcome extreme cold and dwindling power. When you purchase through links on ...

NASA’s TESS spacecraft tracked interstellar comet 3I/ATLAS in January, capturing data on its motion, brightness, and rotation before it left the solar system ...

The latest data from the Webb telescope (reported here) indicates that the plume of gas and dust surrounding 3I/ATLAS contains water (H₂O), carbon dioxide (CO₂), carbon monoxide (CO) and methane (CH₄) ...

Scientists have found new evidence suggesting that interstellar 3I/ATLAS is not an alien spaceship, as one conspiracy theory ...
