NASA’s Curiosity rover has made an unprecedented chemical discovery at a new Mars location, revealing unexpected complexity in the planet’s ancient geological environment.
Astronomers report the strongest evidence yet that a molten rocky exoplanet has an atmosphere, challenging long-held assumptions about how planets survive extreme heat.
nterstellar comet 3I/ATLAS is passing close to Earth, giving astronomers a rare chance to study material formed around another star and deepen understanding of cosmic origins.
Scientists have identified a mysterious rock layer about 20 kilometers beneath a major Atlantic island, suggesting a more complex geological history than previously believed.
Scientists have discovered a uniquely thick rock layer more than 12 miles beneath Bermuda’s crust — a geological feature unlike any seen elsewhere, raising new questions about Earth’s deep structure.
China’s Taikonauts installed debris protection panels on its Tiangong space station’s exterior during recent spacewalks, bolstering defenses after a debris impact and highlighting orbital hazards.
Scientists have sequenced the massive genome of the vampire squid, uncovering new clues about cephalopod evolution and revealing how it retains ancient chromosome features linking squids and octopuses.
Astronomers have identified a binary star system where one star is being devoured by its companion and is expected to explode as a supernova so bright it could be visible from Earth in broad daylight.
A Japanese astronaut aboard the ISS has shared striking December images of Earth, highlighting seasonal contrasts, glowing cities, and the planet’s quiet unity from orbit.
The Geminids meteor shower peaks tonight, offering one of the year’s most reliable celestial displays with bright, frequent streaks visible to patient skywatchers.
Dark stars may have shaped the early universe without shining, using dark matter to influence galaxy formation and cosmic structure before conventional light emerged.
The Bay Area will see the Geminid meteor shower at its peak, with bright lights from debris of the old dead comet-like object 3200 Phaethon streaking across the night sky.
A cougar struck by a vehicle in Michigan’s Upper Peninsula survived and walked away, prompting renewed caution from state wildlife officials about road risks in forested areas.
Scientists recommend threatened status for Southern California’s mountain lions as habitat loss, road dangers, and genetic isolation put long-term survival at risk.
New research shows the Amazon is shifting toward a hotter, drier “hypertropical” climate, threatening tree survival and weakening its role as a global carbon absorber.
Astronomers observed a black hole blasting winds at nearly 130 million mph, revealing a powerful phenomenon that shapes galaxies and expands our understanding of cosmic forces.
A new scientific report urges that human missions to Mars prioritize the search for alien life, arguing astronauts are essential for detecting and protecting potential biological evidence.
NASA astronaut and Los Angeles native Jonny Kim has returned to Earth after 245 days on the International Space Station, completing a long-duration mission focused on science and exploration.
NASA has lost contact with its MAVEN spacecraft after a decade orbiting Mars, prompting efforts to reestablish communication with the long-running atmospheric mission.
Scientists have determined that clocks on Mars tick about 477 microseconds per Earth day faster than those on Earth due to weaker gravity and orbital motion, a consequence of Einstein’s relativity that must be accounted for in future Mars navigation and communication systems.
Archaeologists discovered evidence that ancient humans made fire around 400,000 years ago in Suffolk — about 350,000 years earlier than previously believed.
A robotic float drifted under East Antarctica’s ice shelves for eight months — then resurfaced with rare ocean-temperature and salinity data from beneath ice.
SpaceX aims for a mid-2026 IPO, hoping to raise over $30 B and reach a $1.5 T valuation — a record-breaking debut reshaping the boundaries between space and finance.
Chinese astronauts performed a spacewalk to inspect debris damage on Shenzhou-20’s re-entry capsule, triggering safety upgrades and a thorough review of orbital debris risks.
