New research suggests that moons orbiting sunless 'rogue' planets could maintain liquid water and potentially host life for billions of years through internal tidal heating.
Scientists have developed a new theoretical method to analyze the interior of neutron stars, which could confirm the existence of a state of matter from the Big Bang.
NASA has officially begun building its nuclear-powered drone, Dragonfly, which is scheduled to launch in 2028 to explore Saturn's largest moon, Titan.
The European Space Agency's Plato satellite is undergoing critical tests in a massive vacuum chamber, simulating the extreme hot and cold of space.
A small NASA team is preventing collisions between a growing number of spacecraft orbiting the Moon, as a near-miss last year highlighted the rising risks.
New data confirms NASA's DART mission in 2022 permanently altered the solar orbit of the entire Didymos-Dimorphos asteroid system, a historic first.
A 1,300-pound NASA satellite is expected to make a fiery return to Earth this week. Officials state the risk to the public is low, with a 1 in 4,200 chance of harm.
Private companies have taken the lead in space, conducting 70% of global launches in 2024. This commercial surge is driving the space economy toward a projected $1 trillion valuation by 2032.
New data from NASA's DART mission shows the 2022 asteroid impact did more than expected, altering the solar orbit of the entire Didymos-Dimorphos system.
New observations from the James Webb Space Telescope have ruled out any possibility of asteroid 2024 YR4 hitting the Moon in 2032, confirming a safe pass.
The world's first commercial space telescope, Mauve, has successfully captured its first light, beginning a mission to study nearby stars for signs of habitability.
For decades, the mystery of NASA's 700 missing Apollo 11 tapes fueled conspiracy theories. The truth is not a cover-up, but a story of cost-cutting.
Scientists have proposed a high-risk mission to catch interstellar comet 3I/ATLAS by sending a probe on a daring dive toward the Sun to achieve record-breaking speeds.
ESA's Proba-2 satellite captured breathtaking images of a 'ring of fire' solar eclipse on Feb. 17, 2026, an event almost entirely missed by observers on Earth.
A surge in satellite mega-constellations, with over a million new satellites proposed, threatens to permanently alter the night sky and create a crisis in Earth's orbit.
London is preparing to host Space-Comm Expo, Europe's largest space industry event, on March 4-5, gathering over 5,400 global leaders to discuss technology, defense, and investment.
NASA has launched a series of sounding rockets into the aurora borealis from Alaska to study the complex electrical systems that power the northern lights.
Astronomers have witnessed a massive star in the Andromeda galaxy vanish, concluding it collapsed into a black hole without a supernova explosion.
Scientists are re-examining data from NASA's 1976 Viking missions, arguing that the probes did find evidence of microbial life that was misinterpreted at the time.
International Space Station research has been vital in preparing for the Artemis II lunar mission, contributing critical life support systems, health studies, and observation techniques.
