Recently, a group of scientists created a detailed map of this space, showing that the bubble is lopsided in both shape and ...

Humanity has already flung machines into interstellar space, but sending people is a different problem entirely. The physics of propulsion, the fragility of the human body, and the sheer size of the ...

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

The Oort cloud is traditionally thought of as a vast shell of perhaps trillions of icy objects encasing our solar system, serving as the final boundary between us and the dark reaches of interstellar ...

During a close approach to the Sun, the European Space Agency’s Solar Orbiter watched that tipping point unfold in unusually ...

Only two spacecraft have ever truly escaped the solar system, slipping beyond the Sun’s protective bubble into interstellar space. Their measurements are now reshaping how I understand the heliosphere ...

NASA researchers show that artificial intelligence can anticipate solar flare buildups by tracking subtle changes across the ...

A rare discovery beyond Neptune is forcing scientists to rethink early solar system dynamics and the forces that shaped ...

If you travel far enough away from the Sun, the Solar System becomes a lot more populated. Out past the orbit of Neptune lies the Kuiper Belt, a vast, ring-shaped field of icy rocks. This is where ...

Using data collected by NASA's Parker Solar Probe during its closest approach to the sun, a University of Arizona-led ...
