NASA Ends Swift Space Telescope Mission
NASA has ended the Swift space telescope mission after an unsuccessful attempt to stabilize its declining orbit. Its data will continue supporting transient astronomy.
JWST’s Little Red Dots: Galaxies or Black Holes?
JWST’s little red dots may be compact galaxies, rapidly growing black holes, or a mixture of both. Their nature could reshape models of early cosmic history.
How Climate Change May Delay the Next Ice Age
Human-caused greenhouse-gas emissions may delay the next glaciation for thousands of years, but this is not a climate victory. Modern warming is already causing severe risks.
Astronomers Report a Dead Star With a Green Glow
Astronomers reportedly observed a dead stellar remnant associated with an eerie green glow, but the source of the light and the meaning of the claimed first remain unconfirmed.
Cosmic Dawn: How Astronomers Study the First Galaxies
Discover how astronomers use ancient light, infrared observatories, spectroscopy, gravitational lensing, and simulations to study the universe's first stars and galaxies.
NASA Plans Faster, More Frequent Science Mission Selection
NASA is considering a faster, lower-cost process for selecting science missions, but success will depend on rigorous reviews, realistic budgets, and strong oversight.
Could an Armoured Amphibian Have Lived in Ancient Seas?
An armoured amphibian in ancient marine sediments would challenge assumptions about vertebrate evolution, but the supplied sources do not verify the animal or its habitat.
Are We Living Through a Sixth Mass Extinction?
Scientists are reassessing the Big Five mass extinctions while examining whether human-driven biodiversity loss has begun a sixth global extinction.
Lizards Shed Tails 99 Million Years Ago, Study Finds
An amber-preserved lizard tail suggests that anatomy compatible with tail autotomy existed about 99 million years ago, during the Cretaceous Period.
D-rex: What We Know About China’s Giant Fungus
Reports describe D-rex as a giant fungus found in China and linked to an ancient lineage. The 65-million-year figure refers to its evolution, not the individual organism.
Rubin Telescope Could Find More Earth Mini-Moons
The Vera C. Rubin Observatory could discover more of Earth's temporary mini-moons, helping scientists study their orbits, origins and potential as spacecraft targets.
Neutrinos: The Ghost Particles Shaping Modern Physics
Neutrinos pass through Earth, stars, and human bodies almost unnoticed. Their rare interactions reveal how stars work and where particle physics remains incomplete.
Lumina Simulation Maps the Early Universe at Record Scale
The Lumina simulation models cosmic evolution on a record-breaking scale, helping researchers study galaxy formation, rare structures, and the universe’s origins.
Did Global Warming Interrupt an Emerging Ice Age?
Research suggests a long-term cooling trend may have developed since the Roman period before human-caused warming redirected Earth’s climate trajectory.
What Happened to the Neanderthals?
Neanderthals disappeared as a distinct population about 40,000 years ago, likely because climate instability, demographic weakness, competition, disease, and interbreeding acted together.
Birdwatching May Support Brain Health and Healthy Aging
Birdwatching engages attention, memory, visual recognition, and spatial processing. Research suggests possible brain adaptations, but it has not been proven to prevent dementia.
On This Day: Cassini Discovers Iapetus in 1671
On Oct. 25, 1671, Giovanni Cassini discovered Iapetus, Saturn’s two-toned moon. Its dark hemisphere, bright ice, and equatorial ridge still intrigue scientists.
How Coffee Grounds Could Strengthen Concrete
Researchers are converting used coffee grounds into biochar for concrete, exploring a way to reduce landfill waste and develop more sustainable building materials.
Ancient Viral DNA and Human Brain Evolution
Ancient viral DNA may have become regulatory switches that helped shape differences between human and chimpanzee brain development, though evidence remains preliminary.
Hunter’s Moon 2026: When and How to See It
Learn when to see the 2026 Hunter’s Moon, why it may look large or orange, where to watch it, and how to photograph it.
