Thick lithosphere casts doubt on plate tectonics in Venus"s geologically recent past
At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers has used that ancient impact scar to explore the.....»»
New study suggests some forms of life could exist in Venus"s sulfuric acid clouds
A team of chemists and planetary scientists from Worcester Polytechnic Institute, Nanoplanet Consulting and MIT has found evidence that a form of life that uses sulfuric acid as a liquid medium could exist in some of the clouds covering Venus. The te.....»»
Mysterious missing component in the clouds of Venus revealed
What are the clouds of Venus made of? Scientists know it's mainly made of sulfuric acid droplets, with some water, chlorine, and iron. Their concentrations vary with height in the thick and hostile Venusian atmosphere. But until now they have been un.....»»
Plate tectonics in the Archean: Observation versus interpretation
The plate tectonics theory established in the 20th century has been successful in interpreting many geological phenomena, processes, and events that have occurred in the Phanerozoic......»»
TRAPPIST-1c isn"t the exo-Venus we were hoping for, but don"t blame the star
A recent study posted to the arXiv preprint server and accepted to The Astrophysical Journal uses computer models to investigate why the exoplanet, TRAPPIST-1c, could not possess a thick carbon dioxide (CO2) atmosphere despite it receiving the same a.....»»
Miniaturized jumping robots could study an asteroid"s gravity
Missions focusing on small bodies in the solar system have been coming thick and fast lately. OSIRIS-Rex, Psyche, and Rosetta are all examples of projects that planned or did rendezvous with a small body in the solar system. But one of their biggest.....»»
The atmosphere of an exoplanet reveals secrets about its surface
As astronomers have begun to gather data on the atmospheres of planets, we're learning about their compositions and evolution. Thick atmospheres are the easiest to study, but these same thick atmospheres can hide the surface of a planet from view. A.....»»
NASA beamed a cat video back to Earth from deep space
NASA has transmitted an ultra high definition video of a ginger cat named Taters from 19 million miles away from Earth. NASA has a lot on its plate, between staring at strange things on Uranus, monitoring solar flares, investigating Enceladus,.....»»
Exoplanets" climate: It takes nothing to switch from habitable to hell, say researchers
The Earth is a wonderful blue and green dot covered with oceans and life, while Venus is a yellowish sterile sphere that is not only inhospitable but also sterile. However, the difference between the two is only a few degrees in temperature. A team o.....»»
Shaggy dog yarn: Study unravels history and demise of long-haired canine
A little-known dog lineage with fur so thick it was spun into blankets was selectively bred for millennia by Native Americans of the Pacific Northwest until its rapid demise following European colonization, a study in Science showed Thursday......»»
Move over, Blitzen: Geese outpace reindeer impacts on Arctic ecosystems
In the frigid seas halfway between mainland Norway and the North Pole, two types of animals browse the palatable vegetation of a high-tundra archipelago, munching on thick moss, cropped grasses, and low-lying shrubs......»»
Video: Permafrost thaw: A silent menace
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth's surface. Ground that has been frozen for thousands of years, called permafrost, is thawing—addin.....»»
Discovery of 72-kilometer fault line on Canada"s Vancouver Island
A team of geologists, mineralogists and Earth and ocean scientists affiliated with institutions in Canada, the U.S. and France has discovered a 72-kilometer fault line on Canada's Vancouver Island. In their project, reported in the journal Tectonics,.....»»
Catalyzing momentum for health negotiations at COP28
By now, there is no doubt that the climate crisis is also a significant health crisis affecting people across the globe......»»
Evidence that ancient Tethys Ocean influenced Earth"s past environments
A recent study, published in Science China Earth Sciences and led by geologist Bo Wan from the Chinese Academy of Sciences' Institute of Geology and Geophysics, connects the Tethyan plate tectonic movements to changes in Earth's surface environment......»»
Researchers safely integrate fragile 2D materials into devices, opening a path to unique electronic properties
Two-dimensional materials, which are only a few atoms thick, can exhibit some incredible properties, such as the ability to carry electric charge extremely efficiently, which could boost the performance of next-generation electronic devices......»»
Seafloor shapes on the flanks of mid-ocean ridges linked to magma supply
At nearly 65,000 kilometers long, the mid-ocean ridge system is the longest mountain range in the world. Running beneath the ocean's surface, mid-ocean ridges are formed at divergent plate boundaries, where tectonic plates stretch apart and magma ris.....»»

Building blocks for life could have formed near new stars and planets
While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. According to research published in ACS Central Science, the simplest amino acid, carbamic acid, could have f.....»»
