In a groundbreaking discovery, NASA's Pleiades supercomputer has revealed an unexpected spiral structure within the inner Oort cloud, challenging long-held beliefs about our solar system's outer reaches.

"We've run into a lot of challenges along the way [that] have caused us some launch delays, but this team has pulled together and worked diligently to get us over that."

President Trump set the U.S. on a path to sending astronauts back to the lunar surface during his first term. Lately he has expressed more interest in Mars.

The space agency said Wednesday that a sensor on Voyager 2 that analyses charged particles and cosmic rays would be turned off later this month. Last Monday, Nasa turned off an experiment on Voyager 1

The solar system could be packed with 1 million alien visitors, space rocks shaken away from our cosmic neighbor Alpha Centauri, new research has revealed.

NASA engineers are turning off two instruments on Voyager 1 and Voyager 2 to ensure these twin spacecraft can continue exploring interstellar space.

The NASA boffins in white coats and thick-rimmed glasses have detected new signals that show the Oort cloud - the spooky shell of icy objects at the very edge of our solar system - might have spiralling arms that resemble a galaxy.

The farthest spacecraft from Earth are shutting off instruments in interstellar space, but their mission in interstellar space isn’t over yet

Engineers at NASA's Jet Propulsion Laboratory have conserved energy supplies on the record-setting Voyager 1 & 2 deep space probes nearly 50 years after their missions launched to extend them further.

In research highlighted in a new paper, published today in The Astrophysical Journal, Scientia Senior Lecturer Ben Montet and PhD candidate Brendan McKee analysed changes in the timing of a known planet's transit across its star, to infer the presence of a second exoplanet.
