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.....»»
Decades after global regulations, the Arctic Ocean"s legacy persistent organic pollutants haven"t dropped
The presence of persistent organic pollutants (POPs) in all the world's oceans but one has been in steady decline since 2001, when 152 countries agreed on a comprehensive global ban. The exception has been the Arctic Ocean, which has seen a sharp ris.....»»
How many additional exoplanets are in known systems?
One thing we've learned in recent decades is that exoplanets are surprisingly common. So far, we've confirmed nearly 6,000 planets, and we have evidence for thousands more. Most of these planets were discovered using the transit method. though there.....»»
Mangrove degradation threatens carbon storage in China"s Pearl Bay
Carbon sinks are important in the fight against climate change as they draw down atmospheric carbon dioxide levels by storing organic carbon in the oceans and soil, for example. Within tropical and subtropical intertidal locations, wetland plant comm.....»»
Report reveals how the state of our oceans is intrinsically linked to human health
A study published in the journal One Earth explores how marine biodiversity conservation, human health and well-being are connected. The results suggest that marine protected areas can be good for both planet and people......»»
Mars may have been habitable much more recently than thought
Evidence suggests Mars could very well have been teeming with life billions of years ago. Now cold, dry, and stripped of what was once a potentially protective magnetic field, the red planet is a kind of forensic scene for scientists investigating wh.....»»
Newly discovered cyanobacteria could help sequester carbon from oceans and factories
An international coalition of researchers from the United States and Italy has discovered a novel strain of cyanobacteria, or algae, isolated from volcanic ocean vents that is especially adept at growing rapidly in the presence of CO2 and readily si.....»»
Plastics: lifesaver turned environmental threat
Before it threatened biodiversity, the oceans and the global food chain, plastics saved lives and transformed societies as a durable, malleable and cheap material......»»
Did some of Earth"s water come from the solar wind?
The source of Earth's water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth's water was either part of the planet from the beginning of its formation in the solar nebula or delivered later, mayb.....»»
Life can maintain a habitable environment in hostile conditions, research suggests
Everybody knows that for life to thrive on any world, you need water, warmth, and something to eat. It's like a habitability mantra. But, what other factors affect habitability? What if you relaxed the conditions conducive to life? Would it still exi.....»»
Old data yield new secrets as NASA"s DAVINCI preps for Venus trip
Due to launch in the early 2030s, NASA's DAVINCI mission will investigate whether Venus—a sweltering world wrapped in an atmosphere of noxious gases—once had oceans and continents like Earth......»»
Catching prey with grappling hooks and cannons: The unusual weapons arsenal of a predatory marine bacterium
Countless bacteria call the vastness of the oceans home, and they all face the same problem: the nutrients they need to grow and multiply are scarce and unevenly distributed in the waters around them. In some spots they are present in abundance, but.....»»
Plankton balloon to six times their size in newly discovered mode of oceanic travel
Many plankton journey from the cold, dark depths of our oceans to the surface, only to eventually drift down again into the darkness in a perpetual rhythm. Yet, how single-celled phytoplankton, most of which have no appendages to help them swim, make.....»»
Identifying the genes that viruses "steal" from ocean microbes
The microbes that cycle nutrients in the ocean don't do the work on their own—the viruses that infect them also influence the process. It's a vital job for the rest of the planet, enabling oceans to absorb half of the human-generated carbon in the.....»»
Ship-mounted camera systems help increase protections for marine mammals
Vessel strikes and entanglement are some of the leading causes of injury and death to marine animals such as whales. Increasingly urbanized waterways, warming oceans, changes in prey distribution—and in some cases, increasing species populations—.....»»
Reoxygenating oceans: Startups lead the way in Baltic Sea
European scientists have teamed up with two startups in a pioneering experiment to tackle one of the major problems facing sea life—the depletion of oxygen in the ocean, causing the disappearance of fish and marine biodiversity......»»
Europa Clipper blasts off to study whether Jupiter’s icy moon could host life
NASA's Europa Clipper mission aims to study whether the liquid water ocean beneath Europa's icy crust could potentially support life......»»
NASA probe Europa Clipper lifts off for Jupiter"s icy moon
NASA probe Europa Clipper lifted off from the US Kennedy Space Center on Monday, bound for an icy moon of Jupiter to discover whether it has the ingredients to support life......»»
Can life exist on an icy moon? NASA"s Europa Clipper aims to find out
With a spacecraft launching soon, the mission will try to answer the question of whether there are ingredients suitable for life in the ocean below Europa's icy crust......»»
How to watch the Europa Clipper mission launch on Monday
The launch of NASA's Europa Clipper mission to the icy moon of Jupiter was delayed due to Hurricane Milton. Now, the launch could go ahead on Monday......»»
Exoplanet discovered in a binary system could explain why red dwarfs form massive planets
In recent years, the number of known extrasolar planets (aka. exoplanets) has grown exponentially. To date, 5,799 exoplanets have been confirmed in 4,310 star systems, with thousands more candidates awaiting confirmation. What has been particularly i.....»»
