Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected in space and brought to Earth by NASA show evidence of high-carbon content and water.
Earth's amphibians are being pushed closer to the brink due to habitat destruction, disease and climate change, with 41% of species now threatened with extinction.
The densest naturally occurring element on the periodic table is the metal osmium. But there are some objects out there in the Solar System that seem to be way more dense than osmium.
Not all plants are created equal, and not all can survive the harsh conditions of space. One that might thrive on long spacefaring voyages also happens to be the smallest flowering plant on Earth. It is called Watermeal.
There is some evidence suggesting that our physical reality could be a simulated virtual reality rather than an objective world that exists independently of the observer.
The world's most diverse forest, the Amazon, may also host more than 10,000 records of pre-Columbian earthworks (constructed prior to the arrival of Europeans), according to a new study.
A new method for scanning telescope images for the faintest signs of rock far beyond Pluto has uncovered evidence that our Solar System's disc of material extends far further into interstellar space than we thought.
Researchers note a "synchronicity" of geochemical signals suggesting that fragments of a comet struck Earth approximately 13,000 years ago.
An international study found that certain groupings of iron atoms in the Earth’s inner core are able to move about rapidly, changing their places in a split second while maintaining the underlying metallic structure of the iron.
Among the most striking geologic features on the surface of Arrokoth is the ensemble of large, broadly similarly sized mound-like features seen on the larger lobe.
A very rare, strange burst of extraordinarily bright light in the universe just got even stranger. The phenomenon, called a Luminous Fast Blue Optical Transient (LFBOT), flashed onto the scene where it wasn't expected to be found.
Sunlight on Mars interacts with iron-rich dust that hangs in the atmosphere. This ultimately scatters lower-frequency red light through the sky during the day. At twilight, however, the red light is filtered away and the sky glows a cool blue.
A powerful laser was able to deflect a lightning bolt almost 200 feet before it hit a lightning rod, greatly improving the rod's function.
An international team of researchers has developed a new theoretical framework that bridges physics and biology to provide a unified approach for understanding how complexity and evolution emerge in nature.
Resent studies question the evolution of the Moon magnetic field thanks to its demonstration of the existence of the inner core.
