US firm cleared to test a massive space mirror, sparking debate over potential climate impacts and the risk of permanently brightening the night sky. A federal panel has cleared a U.S. firm to launch its inaugural test satellite that will bounce...

A NASA satellite image captured years ago still astonishes scientists with an unexpected feature that sets it apart from every other picture. A striking view of the Great Bahama Bank captured by NASA Earth Observatory continues to draw attention almost...

NASA’s pioneering space-food experiment aims to revolutionize long‑term astronaut nutrition, boosting survival on multi‑year missions. Space crews face a nutritional gap because many vitamins and essential compounds degrade over the years‑long journeys...

Over 34 years since its launch, the Hubble Space Telescope has completed 200,000 orbits while capturing a distant explosion magnified by a galaxy cluster. NASA’s Hubble Space Telescope has officially reached a historic milestone, completing its...

Astronomers have discovered a star stripping material from a brown dwarf in a bizarre, record-breaking 87-minute orbit marked by a strange triangular signal. Astronomers have discovered a rare cosmic feeding cycle unfolding just 300 light-years from...

A Russian military satellite is performing precise maneuvers near a U.S. spacecraft, sparking renewed concerns about escalating surveillance in orbit. A Russian military satellite has engaged in a series of sophisticated, uncoordinated orbital...

See the 1873 comet as it swings close to Earth, giving binoculars a rare view and marking 150 years of scientific observations. Comet 10P/Tempel 2, discovered in the 19th century, will swing through the inner Solar System this summer under one of the...

Astronomers confirm a rare super‑Jupiter on a 180‑day orbit, marking one of the longest‑period transiting exoplanets ever found. A newly confirmed super‑Jupiter that circles its star once every 180 days has been identified after extensive, years‑long...

New Hubble observations suggest comet 41P may have slowed down, stopped, and started spinning the opposite way after its close pass by the Sun in 2017. Comets may look calm in telescope images, glowing softly against the dark sky. But in reality, they...

NASA has successfully tested a new CubeSat propulsion system that integrates two distinct space maneuvers into a single, efficient fuel source. NASA has officially cleared its latest innovation in satellite technology for flight, following a rigorous...

Scientists used a novel technique on NASA data to uncover a previously hidden planet, revealing a world once thought out of reach. NASA’s TESS (Transiting Exoplanet Survey Satellite) has identified a distant exoplanet hidden in its archive by...

ESA’s CRISTAL satellite has passed a critical testing milestone, bringing it one step closer to monitoring Earth’s changing polar ice from space. Europe’s upcoming polar monitoring mission has cleared a critical engineering hurdle, moving the CRISTAL...

A mysterious rocky exoplanet once thought to break the laws of physics may be an illusion, as new data challenges our understanding of its true size. The existence of “mega-Earths”—massive, dense rocky worlds that seem to defy standard planetary...

NASA’s Roman Space Telescope moves into final Falcon Heavy integration, nine months early, aiming for an August launch. NASA’s Nancy Grace Roman Space Telescope is moving through a critical stage of its launch campaign at Kennedy Space Center, as...

NASA astronauts have completed the 100th U.S. spacewalk at the International Space Station, marking a major milestone in orbital engineering and power upgrades. NASA has reached a significant operational milestone aboard the International Space Station...

A unique orbital alignment between Ganymede and Io has unveiled the complex, hidden choreography governing the moons of Jupiter. Astronomers have captured a rare celestial dance as two of Jupiter’s largest moons crossed paths, creating a stunning...

Spacecraft designers are reimagining windows, balancing structural safety and the psychological need for astronauts to view Earth from space. As humanity prepares for long-duration missions to the Moon, Mars, and beyond, spacecraft designers are...

In a daring race against time, two cosmonauts braved a frozen, dead Salyut 7 space station to pull off one of history’s most complex orbital rescues. In February 1985, the Soviet Salyut 7 space station effectively became a ghost ship. A catastrophic...

Astronomers have detected an unusual signal from a distant star, revealing a mysterious giant planet that opens a groundbreaking new line of investigation. Astronomers have uncovered a curious celestial anomaly: a massive gas giant known as TOI-1355 b,...

The U.S. has officially confirmed the deployment of operational space control weapons designed to counter hostile actions and defend assets in orbit. The United States has officially confirmed the deployment of orbital space control weapons designed to...
