Astronomers have detected mysterious X-ray signals coming from a nearby white dwarf star for more than 40 years. We may now know where they’re coming from – the death throes of a planet being torn to shreds and raining down on the star.

A pair of extraordinary space missions that have been headed out of the solar system for almost half a century are getting a new lease on life as NASA engineers order the Voyager 1 and 2 deep-space probes to shut down two instruments to save power.

Asteroid 2024 YR4 has grabbed headlines lately, after NASA briefly gave it had the highest ever chance of an impact for an asteroid of hazardous size. Thankfully, new observations have dropped that probability to almost zero – for Earth, anyway.

A retro-futuristic spacecraft with a mixture of the old and new has passed a major milestone as it's readied for its debut orbital mission. Sierra Space has announced that its Dream Chaser cargo spaceplane has demonstrated that it can handle payloads.

Asteroid Bennu seems to have come from a long-lost world on the fringes of the solar system, where saltwater pooled and dried over thousands of years and life’s basic ingredients were widespread.

Next time you're driving around on Mars and need to get your tire replaced, chances are good it'll look something like a revolutionary new version made by NASA and Goodyear. The mesh cage design can take a beating and roll right on.

NASA has confirmed that its Parker Solar Probe is safe and fully operational after its Christmas Eve close encounter with the Sun. On December 24, 2024, the robotic probe came within a record 3.8 million miles (6.1 million km) of the Sun's surface.

Astronomers have discovered an exoplanet with a tail, like a gigantic comet. The planet, known as WASP-69b, is slowly evaporating in the radiation of its host star.

The two NASA astronauts "not stranded" on the International Space Station (ISS) are "not stranded" for another month. Due to a delay in the next crew rotation mission, Butch Wilmore and Suni Williams will remain on the station until late March.

Future space helicopters may benefit as NASA completes history's first interplanetary aircraft crash inquiry. The yet-to-be-released technical report explains why the space agency's Ingenuity Mars helicopter crashed on January 18, 2024.

NASA's X-59 aircraft has been marching toward a fest flight since it entered development in 2016 with the goal of bringing back commercial supersonic travel. Next, the agency will test jet-mounted shock-sensing cones to measure its "sonic thuds."

The Artemis II and III missions slated to return US astronauts to the Moon have been set back. At a press conference, NASA officials said that problems with the heat shield and life support systems would delay the launches until 2026 and 2027.
