NASA's Perseverance Mars rover recently came across an odd rock, dubbed "Phippsaksla," that is unlike anything else the robot has found on the Red Planet. It turns out that it probably isn't from our neighboring world and likely crashed on Mars instead.

NASA's treasure trove of new comet 3I/ATLAS images provides hotly anticipated views of the interstellar visitor, including from Mars and the sun.

NASA's highly anticipated comet 3I/ATLAS images have been released, with a space agency official shooting down alien rumors and stressing that the interstellar visitor is a comet.

NASA will finally share long-awaited images of interstellar object 3I/ATLAS taken during the comet's close flyby of Mars. A live stream has been set for today (Nov. 19).

Twin Mars spacecraft were due to launch on Blue Origin's New Glenn rocket on Nov. 12, but an active sun prompted NASA to delay its mission until Thursday (Nov. 13).

NASA and Lockheed Martin’s X-59 "quiet" supersonic plane flew for the first time in October. It’s a major step towards reintroducing commercial supersonic flight in the United States.

Interstellar comet 3I/ATLAS is briefly out of view as it travels around the sun this week, but researchers and amateur astronomers used spacecraft data to track its progress right up until perihelion.

While scouring images from the James Webb Space Telescope, astronomers spotted Capotauro, "one of the most puzzling discoveries" to date.

NASA's OSIRIS-APEX mission, which was one of 19 designated to be canceled by the Trump administration, has been saved from the chopping block in a last-minute decision. There will be a significant change to its structure, however.

Researchers have discovered that interstellar comet 3I/ATLAS has been shedding water, providing insights into the building blocks of life outside of our solar system and the evolution of interstellar comets.
