Planets too close to their star are too hot (such as Venus), those too far, are too cold (like Mars), whereas planets in the habitable zone are just right....
A strange phenomenon called visual masking can reveal the timescale of perception, but the underlying mechanisms are not well understood.
The colored plots...
Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear...
Pterygotid eurypterids (sea scorpions), giant aquatic arthropods with big claws, were all regarded as apex predators but some scientists then suggested...
There are more than 200 moons in our Solar System, but their relatively small sizes make similarly sized extrasolar moons (exomoons) very hard to detect...
Researchers have described a new species of the genus Calotes from southern China and northern Vietnam.
Photographs of live specimens and their habitats:...
The carbon atom provides the backbone for the complex organic chemistry composing the building blocks of life. The physics of the carbon nucleus in its...
Researchers at the Smithsonian Institution’s National Museum of Natural History have performed a comprehensive taxonomic review of the soft-furred hedgehog...
In a largely sleep-deprived society, quantifying the effects of sleep loss on emotion is critical for promoting psychological health. In a new systematic...
Scientists have identified a new genus and species of true toad from a single specimen found in the high forests of Mount Kenya, an extinct volcano in...
Baleen whales (mysticetes) include the largest animals on the Earth. How they achieved such gigantic sizes remains debated, with previous research focusing...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed a disk bending wave in BRI 1335-0417, the oldest known spiral galaxy...

An artistic reconstruction...
Astronomical observations show that polycyclic aromatic hydrocarbons (PAHs) are abundant and widespread in the interstellar medium. PAH molecules consist...
A Type Ia supernova named Encore is the second multiply-imaged supernova detected in MRG-M0138, a galaxy around 10 billion light-years away in the constellation...
