Most meteorites from Mars are just a few hundred million years old, and likely come from relatively recent volcanic events such as the eruptions on the largest volcano in the solar system, Olympus Mons.
Human activities are making the globe saltier, specifically in our soils, fresh water and air, according to a new study. The excess salt has already caused serious issues in freshwater supplies in recent decades.
A new study has shown that the Southern Hemisphere has been drying out more than the Northern Hemisphere over the past two decades (2001-2020).
A system of seven sweltering planets has been revealed by continued study of data from NASA's retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system.
The phenomenon might play a role in the formation and evolution of fog and clouds, and thus would be important to incorporate into climate models to improve their accuracy.
A pyramid hidden within a hill on an island in West Java, Indonesia, could be the world’s oldest. Gunung Padang, also known as “mountain of enlightenment”, sits at the top of an extinct volcano and is considered a sacred site by locals.
Long ago, an alien planet crashed into Earth – causing a collision so big the debris formed the Moon and left mysterious remnants lodged deep in the Earth’s mantle.
Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Brazil's rapid expansion of soy production has meant an associated rise in pesticide use. Researchers found a statistically significant correlation between soy expansion and acute lymphoblastic leukemia deaths in children between 2008 and 2019.
Fine dust suspended in the atmosphere may have played a significant role in the extinction of dinosaurs after all.
Within 12 hours Hurricane Otis which slammed into the coastal city of Acapulco, Mexico went from a regular tropical storm to a “category 5” hurricane, the most powerful category and one which might occur only a few times worldwide each year.
Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
Disposable diapers are a huge source of global waste, largely because they're difficult to recycle. A new process, however, could salvage the "superabsorber" polymer utilized in the liners of those diapers.
With only one habitable planet (Earth) and one technologically advanced civilization (humanity) as examples, scientists are still confined to theorizing where other intelligent life forms could be.
Two new papers show a 150 kilometer-thick layer of molten silicate rock at the base of the mantle envelopes Mars' liquid iron-alloy core.
