Among mammals, larger species generally have longer lifespans, ranging from a few years for mice to nearly 200 years for some whale species. However, when scientists examine differences within each species, they often find exactly the opposite: smaller animals tend to live longer than their larger counterparts. This is particularly evident in dogs. Great Danes … Read more

One of the most dangerous glaciers on Earth is emerging as a potentially larger driver of future sea level rise than previously thought. A team of glaciologists from the University of California and NASA’s Jet Propulsion Laboratory developed a new ice sheet model to obtain a more accurate projection of the melting of the Thwaites … Read more

A SpaceX rocket provided a stunning pre-dawn display over Florida as a huge, luminescent “jellyfish cloud” stretched for miles, caused by an expanding plume of fuel exhaust crystallizing in the sky and reflecting sunlight off frozen particles. The phenomenon occurred shortly after Tuesday’s 6:33 a.m. ET launch of the Falcon 9 rocket carrying cargo to … Read more
Now you see them, now you don’t. Scientists have discovered that some of the most powerful explosions in the universe, hypernovae, may not occur at all. These explosions, known as hypernovae, were first proposed to explain unusual stars in the halo of our Milky Way galaxy and a neighboring dwarf galaxy. It was suggested that … Read more
A scorching planet nearly 320 light-years from Earth has provided the first direct evidence of a fundamental assumption about how planets form. Astronomers discovered that WASP-189b shares an important chemical feature with its host star, supporting a long-standing idea that also helps scientists investigate potentially habitable worlds. The breakthrough came with the first simultaneous measurement … Read more
The partial skull of a tiger-sized predator that roamed what is now the Isle of Wight off the southern coast of England about 120 million years ago is giving scientists a better understanding of an enigmatic group of carnivorous dinosaurs known for chasing down prey and tearing it apart with enormous claws. The researchers said … Read more
When geologist J. Harlen Bretz proposed the idea that the rugged canyons and hills of eastern Washington did not form gradually but were carved out in days by a cataclysmic flood, his colleagues called him a quack. In 1923 everyone knew that geology is measured in millennia, not days. Huge canyons and hills simply couldn’t … Read more
