A Nasa spacecraft that picked up pieces of an asteroid is leaking them into asteroid on its way home, the space agency has said. The probe picked up such as substantial sample that a rock is wedged against the container door, which means they are falling out back into space.

NASA is expected to announce a new discovery about the moon on Monday. The space agency plans to share findings from its Stratospheric Observatory for Infrared Astronomy (SOFIA) mission during a press conference at 12 p.m. EDT.

Alien hunters deploy new telescopes and tactics—and win some respect

What do Albert Einstein, the Global Positioning System (GPS), and a pair of stars 200,000 trillion miles from Earth have in common?

By combining photonics with artificial intelligence, University of Sydney scientists have developed a sensor that will help decipher the 'twinkle' of stars and allow for Earth-based exploration of planets around distant stars. Their invention will be deployed in one of the world's largest telescopes at Mauna Kea, Hawaii.

Flying observatory that made new discovery is able to ‘pick up phenomenon impossible to see with visible light’, space agency notes

New satellite imagery of California reveals not just the extent of its wildfire damage, but the depth of the loss.

Space is more densely packed than astronomers thought.

A NASA spacecraft touched down on the rugged surface of the Bennu asteroid on Tuesday, grabbing a sample of rocks dating back to the birth of the solar system to bring home.

Some interesting stuff has been taken to the moon. What would you bring?

Millions of space nerds reacted with joy Monday to a study showing the atmosphere of Venus contains phosphine, a chemical byproduct of biological life. But none would have been more thrilled or less surprised by the discovery than the late, great Carl Sagan — who said this day might come more than 50 years ago.

The commander of Boeing’s first astronaut flight has pulled himself off the crew so he’s on Earth — not at the International Space Station — for his daughter’s wedding next year. It’s the second crew switch for Boeing’s Starliner capsule, grounded until the end of this year or early next because of software problems encountered during the first test flight last December.

Starman got less than 5 million miles from the Red Planet.

NASA needs to have a new lunar lander and giant rocket ready by next year in order to return astronauts to the moon by 2024, the space agency's chief Jim Bridenstine told Congress Wednesday (Sept. 23). In a Senate appropriations committee hearing, Bridenstine said NASA aims to send an uncrewed mission, called Artemis 1, around the moon in November 2021 to prepare for the first orbital mission with astronauts two years later, Artemis 2. The Artemis 3 mission would follow, sending astronauts to the south pole of the moon in 2024.
