Fine dust suspended in the atmosphere may have played a significant role in the extinction of dinosaurs after all.
Record concentrations of a helium isotope found inside 62-million-year-old Arctic rocks could be the most compelling evidence to date of a slow leak in our planet's core.
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.
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.
The ozone hole over Antarctica is one of the biggest on record, roughly three times the size of Brazil. It's a natural phenomenon, but scientists are concerned climate change could begin reopening ozone holes.
A similar solar storm today would be catastrophic for modern technological society—potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions of pounds.
In 250 million years, for the first time since Pangea cracked apart, the continents of Earth will crash together into a new supercontinent dubbed Pangea Ultima.
Six of nine planetary boundaries—climate change, deforestation, biodiversity loss, synthetic chemicals including plastics, freshwater depletion, and nitrogen use—are already deep in the red zone, an international team of 29 scientists reported.
The most high-resolution map yet reveals something we previously never knew about: an ancient ocean floor that may wrap around the core. This thin but dense layer exists around 2,900 kilometers below the surface.
NASA has awarded a contract to TransAstra to clean up space junk. One category of debris they will target is CubeSats, small satellites the size of a Rubik’s Cube. The recycling centers would allow the collected debris to be recycled.
The Deniliquin structure spans up to 520 kilometres in diameter. This exceeds the size of the near-300km- wide Vredefort impact structure in South Africa, which to date has been considered the world's largest.
We’ve known about the vents above for a long time, but this is basically a completely new ecosystem below.
Scientists are seeking to confirm that a black rock discovered in Morocco in 2018 departed Earth's pull for outer space, only to return to it like a prodigal child.
In a recent study, more than 40 international scientists assessed the planet’s capacity to provide a safe future. What they concluded is that Earth would fail in 7 of the 8 boundaries for a safe planet.
