UNIVERSE TODAY - Mars holds a special place in the Solar System. It represents marginal habitability. This means it transitioned from warm and wet and potentially hospitable, to cold and dry and inhospitable. What can its transition tell us about exoplanet habitability? New research to be published in the Planetary Science Journal examines the question...
SCIENTIFIC AMERICAN - Today a stretch of Canada’s remote Northwest Territories is covered in snow-covered peaks. But more than half a billion years ago this wilderness was an ancient seafloor home to the wrinkled pancakes, fleshy fronds and spiral-shaped critters that were among Earth’s earliest complex life-forms. Researchers recently unearthed a trove of fossils that...
The Department of Earth & Planetary Sciences at the University of California, Riverside has launched the new UCR Experimental Landscapes Facility, an innovative research space designed to help scientists better understand how landscapes evolve over time. Led by Eric Barefoot, Assistant Professor of Earth & Planetary Sciences, the facility allows researchers to recreate scaled-down versions...
EARTH.COM - The majority of California’s water comes from the Pacific Ocean. Atmospheric rivers build over the sea, ride the jet stream east, and slam into the Sierra. When forecasters track wet winters, they watch ocean temperatures off the coast to predict weather conditions. However, they may need to look beyond what is proximate. A...
EARTH.COM - Space agencies have spent decades designing life-detection instruments around a single idea: biology leaves specific molecules behind. Send the right probe, find the right chemicals, and the question of whether life existed answers itself. The idea has a flaw. Those same molecules form without life in cold meteorite chemistry and deep-sea vents. A...
THE WEATHER NETWORK - Scientists may have solved a mystery of how Earth recycles its carbon, and what it could mean for the future. The general understanding of how Earth's climate is regulated is that it happens through the climate-sensitive reaction of carbon dioxide (CO2) removal by the weathering of silicate rocks on land. As...
NEW SCIENTIST - Compared with Earth, Mars is tiny, yet it seems to have an outsized effect on our planet’s climate cycles. Similar small planets could affect the climates of worlds beyond our solar system, which we must begin to take into account when evaluating their potential habitability. Stephen Kane at the University of California...
THE WEEK - Small but mighty, the red planet — our celestial neighbor — has made Earth’s climate what it is today. Mars’ gravitational pull serves as a stabilizing force for our home’s orbit, tilt and position from the sun. Without it, life could potentially have been a lot different from what we know today...
ZME SCIENCE - Mars is about half Earth’s size and roughly a tenth its mass — not really the sort of planet you’d expect to leave fingerprints on Earth’s climate history. Yet a new set of simulations by an international group of researchers suggests the Red Planet helps shape some of the slow, repeating orbital...
DAILY GALAXY - Mars, long admired for its rusty hue and alien deserts, may play a far greater role in shaping life on Earth than once believed. A new study published in the Publications of the Astronomical Society of the Pacific reveals that Mars’ gravitational influence subtly but significantly affects Earth’s climate cycles, planetary tilt...
