Some icy exoplanets may have habitable oceans and geysers
A NASA study expands the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) could have oceans of liquid water, an essential ingredient for life, beneath icy shells. Water from these oceans could.....»»
The next generation LIFE telescope could detect some intriguing biosignatures
The Large Interferometer for Exoplanets (LIFE) project is an ambitious plan to build a space telescope with four independent mirrors. The array would allow the individual mirrors to move closer or farther apart, similar to the way the Very Large Arra.....»»
Ocean biodiversity could be protected with green hydrogen byproduct, study shows
Climate change, warming temperatures and an increase in nutrient density in the world's oceans are causing a steady loss of oxygen in the marine environment and posing a serious threat to biodiversity......»»
Study says ice age could help predict oceans" response to global warming
A team of scientists led by a Tulane University oceanographer has found that deposits deep under the ocean floor reveal a way to measure the ocean oxygen level and its connections with carbon dioxide in the Earth's atmosphere during the last ice age,.....»»
Simulations show that exoplanets heated at deeper depths by their host stars display markedly different weather patterns
For many years, most astrophysical models assumed that planets beyond our solar system, known as exoplanets, are heated at similar depths by their host stars (i.e., stars like the sun around which planetary systems are formed). Analyses of recent obs.....»»
TESS discovers nine new "hot Jupiters"
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered nine new "hot Jupiter" exoplanets. One of the newly detected alien worlds is almost four times more massive than Jupiter. The finding was p.....»»
Global warming pushes ocean temperatures off the charts: study
In 2023, the world's oceans took up an enormous amount of excess heat, enough to "boil away billions of Olympic-sized swimming pools," according to an annual report published Thursday......»»
Information Theory Can Help Us Search for Life on Alien Worlds
Information theory can help us decode signs of biological activity hiding in the atmospheres of distant exoplanets.....»»
Researchers explore the impact of microplastics and toxin exposure on goldfish
The presence of plastics in our oceans and waterbodies is one of the most significant threats to marine ecosystems. In 2022, plastic production exceeded 400 million tons globally, which continues to rise. The presence of microplastics, ranging in siz.....»»
US Atlantic coastline is sinking, new study claims
The glaciers around our planet are slowly melting, releasing more water into the oceans. We’ve seen plenty of studies discussing what will happen if the … The post US Atlantic coastline is sinking, new study claims appeared first on BGR......»»
Daily Telescope: A crab found in the night sky rather than the world’s oceans
Oh, to have seen this supernova back in the day. Enlarge / The Crab Nebula in all its glory. (credit: Paul Macklin) Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough lig.....»»
AI predicts the influence of microplastics on soil properties
Plastic waste and its buildup in nature has become a major environmental concern in recent times. While plastic pollution in the oceans is undoubtedly a problem, the presence of plastics in soils around the world is also known to cause severe environ.....»»
New research reveals how to obtain high-quality DNA from marine samples
The oceans are still the most underexplored part of our planet. Diversity of large organisms in the Arctic Ocean has been investigated in many ways, yet research on the diversity of Arctic microorganisms is lacking. One of the problems, apart from in.....»»
Marine heat waves: Why the East Sea experienced extreme conditions in 2021
Extreme environmental events are becoming an ever more pressing concern with the continued stresses of climate change, both on land and in the marine realm. While terrestrial heat waves tend to occur over a few days, those in the oceans often have lo.....»»
People once lived in a vast region in north-western Australia—and it had an inland sea
For much of the 65,000 years of Australia's human history, the now-submerged northwest continental shelf connected the Kimberley and western Arnhem Land. This vast, habitable realm covered nearly 390,000 square kilometers, an area one-and-a-half time.....»»
Shipwrecks teem with underwater life, from microbes to sharks
Humans have sailed the world's oceans for thousands of years, but they haven't all reached port. Researchers estimate that there are some three million shipwrecks worldwide, resting in shallow rivers and bays, coastal waters and the deep ocean. Many.....»»
Astronomers scan hundreds of stars for "anomalous transits"
Telescopes have been collecting copious amounts of data on exoplanets in recent years. One of the most common datasets tracks what are known as transits, when an exoplanet crosses in front of its host star and dims the star's light slightly as it doe.....»»
Study shows how vertebrates shape the North Sea seafloor
The world's oceans are a vast habitat for countless creatures that settle, spawn, dig or feed on the seafloor. They also influence the shape of the ocean floor. How exactly this takes place has scarcely been investigated......»»
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.....»»

Researchers: Frozen methane under the seabed is thawing as oceans warm, and things are worse than we thought
Buried beneath the oceans surrounding continents is a naturally occurring frozen form of methane and water. Sometimes dubbed "fire-ice" as you can literally set light to it, marine methane hydrate can melt as the climate warms, uncontrollably releasi.....»»
