The International Space Station is abuzz with the return of one of NASA’s Astrobee smart robots. The yellow Honey Astrobee, one of three free-flying robots,

In 2009 a giant star 25 times more massive than the sun simply vanished. OK, it wasn't quite that simple. It underwent a period of brightening, increasing in luminosity to a million suns, just as if it was ready to explode into a supernova. But then it faded rather than exploding. And when astronomers tried to see the star using...

NASA's OSIRIS-REx sample collection from asteroid Bennu exceeded expectations in material quantity, slowing the curation process. Advanced analysis methods are underway, with a more detailed examination planned for the coming weeks. The initial curation process for NASA’s OSIRIS-REx sample of ast

Whether or not UFOs exist, we need to pay attention to how they are influencing our politics and culture

A large, gaseous planet orbits a red giant star that should have destroyed it. It's 530 light-years from Earth.

India's sun-monitoring spacecraft has crossed a landmark point on its journey to escape "the sphere of Earth's influence", its space agency said, days after the disappointment of its moon rover failing to awaken.

Study reveals how magma oceans may affect the evolution of hot exoplanets. Lava worlds, massive exoplanets home to sparkling skies and roiling volcanic seas called magma oceans, are distinctly unlike the planets in our solar system. To date, nearly 50% of all rocky exoplanets yet discovered ha

NASA is funding eight new studies aimed at better understanding how the human body reacts to spaceflight. These studies will be done on Earth without the need

Liftoff is scheduled for 6:39 p.m. ET tonight (Sept. 29).

China is the latest nation to study lunar lava tubes as locations for bases. They provide natural protection that's impossible to ignore.

In 1960, Freeman Dyson proposed how advanced civilizations could create megastructures that enclosed their system, allowing them to harness all of their star's energy and multiplying the habitable space they could occupy.

Astronomers have spotted a gigantic void they believe to be a baryon acoustic oscillation — a relic from when the universe was a fiery plasma soup

In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star.

OSIRIS-REx's samples of asteroid Bennu will land at 10:42 a.m. EDT (1442 GMT), while the spacecraft itself heads to a new target.

The German project aims to explore beneath Earthly ice as a test for space exploration.

Of all the objects in the Solar System, perhaps the most spectacular are the great comets that occasionally grace our skies. If you’ve been on social media in the past few days, you’ve probably seen articles proclaiming we have such a comet in our skies right now: C/2023 P1 (Nishimura).

Scientists studied the Squid Galaxy, Messier 77, to determine how chemicals swirl around its shrouded central black hole.

NASA is eyeing a privately built 'Apollo' space robot for continued investment — and future space missions.

Planning is underway for NASA's Habitable Worlds Observatory In early August, scientists and engineers gathered in a small auditorium at Caltech to discuss how to build the first space telescope capable of detecting life on planets like Earth. The proposed mission concept, called the Habitable Worl

The curvature of space-time around a colossal mass has yielded the most detailed measurement of the cosmic distribution of dark matter yet.

Queen’s researchers lead the discovery of two potential polar ring galaxies. A group of international astronomers, including researchers from Queen’s University, has identified two potential polar ring galaxies, according to results published on September 13 in the Monthly Notices of the Royal As

NASA's Small Bodies Assessment Group wants the agency to send spacecraft to visit the asteroid Apophis before it makes a close approach to Earth in 2029.

The decadal survey has highlighted such investigations as the effects of space on biology as being key to NASA's next 10 years and to the Artemis mission.

NASA's Lucy spacecraft provides its first glimpse of asteroid Dinkinesh. Over a span of two months, Lucy will get closer, testing its systems before a close flyby on November 1, 2023. The small dot moving against the background of stars is the first view from NASA’s Lucy spacecraft of the main be

NASA's quest for extraterrestrial life now includes technosignatures, evidence of advanced civilizations on distant exoplanets. Through AI, new research methods, and a broadened focus, scientists remain hopeful in discovering life beyond Earth. Our first confirmed proof of life beyond Earth might
