Earth is not necessarily the best planet in the universe. Researchers have identified two dozen planets outside our Solar System that may have conditions more suitable for life than our own. Some of these orbit stars may be better than even our Sun. A study led by Washington State University scientist Dirk Schulze-Makuch, recently published ...
A new study by University of Alberta physicists provides an explanation for why changes to Earth’s magnetic field over time are weaker over the Pacific region — a mystery scientists have been trying to solve for nearly a century. “This is something that has been a puzzle since the 1930s when it was first noticed,” ...
New Curtin University-led research has uncovered how rocks sourced from the Earth’s mantle are linked to the formation and breakup of supercontinents and super oceans over the past 700 million years, suggesting that the planet is made up of two distinct “faces.” The research, published in the leading journal Nature Geoscience, examined the chemical and ...
Earth’s molten core may be leaking iron isotopes, according to researchers who analyzed how iron behaves inside our planet. The boundary between the liquid iron core and the rocky mantle is located some 1,800 miles (2,900 km) below Earth’s surface. At this transition, the temperature drops by more than a thousand degrees from the hotter ...
Ancient rocks from Greenland have shown that the building blocks necessary for the evolution of life did not come to Earth until very late in the planet’s formation — much later than previously thought. An international team of geologists — led by the University of Cologne and involving UNSW scientists — have published important new ...
The precursor of our planet, the proto-Earth, formed within a time span of approximately 5 million years, shows a new study from the Centre for Star and Planet Formation (StarPlan) at the Globe Institute at the University of Copenhagen. On an astronomical scale, this is extremely fast, the researchers explain. If you compare the solar system’s ...
An international team of researchers says findings reveal a daunting outlook for our changing climate. Chi Chen, a Boston University graduate researcher, and Ranga Myneni, a BU College of Arts & Sciences professor of earth and environment, are authors of a new paper that reveals how humans are helping to increase the Earth’s plant and ...
A new paper quantifying small levels of iodine in Earth’s stratosphere could help explain why some of the planet’s protective ozone layer isn’t healing as fast as expected. The paper posits a set of connections that link air pollution near the Earth’s surface to ozone destruction much higher in the atmosphere. That higher-level ozone protects ...
Stars have life cycles. They’re born when bits of dust and gas floating through space find each other and collapse in on each other and heat up. They burn for millions to billions of years, and then they die. When they die, they pitch the particles that formed in their winds out into space, and ...
Data from ESA’s Cluster mission has provided a recording of the eerie “Earth’s magnetic song” that Earth sings when it is hit by a solar storm. The song comes from waves that are generated in the Earth’s magnetic field by the collision of the storm. The storm itself is the eruption of electrically charged particles ...
