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.
NASA's first asteroid samples fetched from deep space parachuted into the Utah desert Sunday to cap a seven-year journey.
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.
Astronomers using data from NASA’s James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Jupiters moon Europa.
Expedition 69 crew members on the ISS marked a busy week with cleaning, maintenance, and experiments. Frank Rubio, Sergey Prokopyev, and Dmitri Petelin celebrated a year in space, while others contributed to diverse tasks and scientific investigations.
The German project aims to explore beneath Earthly ice as a test for space exploration.
The U.S. Department of Defense wants fresh ideas on how to maintain military superiority in space.
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.
The sun’s outer atmosphere is vastly hotter than its surface. Scientists may be close to figuring out why.
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
Triton orbits to the beat of its own drum.
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
Scientists have discovered that cosmic structures grow slower than Einstein's Theory of General Relativity predicts, with dark energy playing a more dominant inhibitory role than previously thought. This finding may reshape our understanding of dark matter, dark energy, and fundamental cosmic theori
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
A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b...
The Apollo 17 lunar lander base is creating small-scale moonquakes on a daily basis.
Astronomers have discovered the first "bubble of galaxies," an almost unimaginably huge cosmic structure thought to be a fossilized remnant from just after the Big Bang sitting in our galactic backyard.
