The earliest atmosphere on Mercury
Mercury is a most unusual planet. The smallest planet in the solar system, and the closest planet to the sun, it is in a 3:2 spin resonance, slowly turning and experiencing scorching heat up to 430 degrees Celsius, and the night side frigid, down to.....»»
Adapting to hypoxia: Zooplankton influence efficiency of biological carbon pump in the Humboldt Current
Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ocean where it can be stored for long periods of time. Until now, this.....»»
Video: Tracking human emissions from space
The Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) mission will be the first satellite mission to measure how much carbon dioxide is released into the atmosphere through human activity......»»
Jet stream will get faster as climate change continues, study finds
A new study in Nature Climate Change takes one of the first deep dives into how climate change will affect the fastest jet streams—the powerful, narrow winds in the upper atmosphere that steer much of the Earth's weather systems and are connected t.....»»
Researchers investigate how climate change drivers reshape ocean methane and nitrous oxide cycles
The ocean is a critical life-support system for our planet through its role in global climate regulation. It absorbs most of the carbon emissions and heat trapped in the atmosphere, which result from human activities. Over the years, this has led to.....»»
Deep within an inhospitable desert, a window to first life on Earth
CU Boulder geologist Brian Hynek has helped to document what may be a unique kind of ecosystem on Earth—and a possible window into the earliest stages of life on this planet 3.5 billion years ago, and even life on ancient Mars......»»
New fungus is the oldest disease-causing species found to date
The earliest disease-causing fungus has been discovered within the Natural History Museum's fossil collections. The new fungal plant pathogen, Potteromyces asteroxylicola, which is 407-million-years-old, has been named in honor of celebrated Tales of.....»»
Don"t expect under-screen Face ID tech until iPhone 18 at the earliest
A publication that draws info from Apple's supply chain is moving goalposts again, and is now saying that Face ID under the screen isn't coming until "after 2026."The rumors of an all-screen iPhone with no camera penetrations is evergreen, and goes b.....»»
Scientists develop a new high-efficiency mercury removal photocatalyst
Scientists from Shanghai University of Electric Power of College of Energy and Mechanical Engineering have developed a new high-efficiency mercury removal photocatalyst......»»
How are toxic brown carbon nitroaromatics produced in biomass smoke?
Biomass burning from wildfires puts large amounts of aromatic hydrocarbons in the atmosphere every year, which are thought to convert into more light-absorbing and toxic nitroaromatics......»»
Scientists just revealed the colossal amount of CO2 emitted in 2023
Researchers released the 2023 Global Carbon Report, which detailed how much carbon dioxide nations emitted into the atmosphere this year. Emissions grew 1.1 percent higher in 2023. Global carbon emissions are projected to go up in 2023 and are.....»»
Earliest-known fossil mosquito suggests males were bloodsuckers too
Researchers reporting in the journal Current Biology on December 4 have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing mouthpart.....»»
One of the largest magnetic storms in history quantified: Aurorae from the tropics to the polar regions
In early November of this year, aurora borealis were observed at surprisingly low latitudes, as far south as Italy and Texas. Such phenomena indicate the impacts of a solar coronal mass ejection on the Earth's magnetic field and atmosphere. Far more.....»»
Carbon dioxide becomes more potent as climate changes, study finds
A team of scientists found that carbon dioxide becomes a more potent greenhouse gas as more is released into the atmosphere......»»
An anisotropic density turbulence model from the sun to 1 au derived from radio observations
Density turbulence in the solar corona and solar wind is evident via the properties of solar radio bursts; angular scattering-broadening of extra-solar radio sources observed through the solar atmosphere, and can be measured in-situ in the solar wind.....»»
ISS astronauts witness fiery end of Russian spaceship
Astronauts on the space station witnessed the fiery demise of a Russian spacecraft on Wednesday as it burned up in Earth’s atmosphere at high speed......»»
ISS astronauts witness fiery end of Russian cargo ship
Astronauts on the space station witnessed the fiery demise of a Russian spacecraft on Wednesday as it burned up in Earth’s atmosphere at high speed......»»
A tiny quadcopter could gather rocks for China"s sample return mission
Space exploration is always changing. Before February 2021 there had never been a human made craft flying around in the atmosphere of another world (other than rocket propelled landers arriving or departing). The Mars Perseverance rover changed that,.....»»
Aerocapture is a "free lunch" in space exploration
When spacecraft return to Earth, they don't need to shed all their velocity by firing retro-rockets. Instead, they use the atmosphere as a brake to slow down for a soft landing. Every planet in the solar system except Mercury has enough of an atmosph.....»»
Marine biota birth new atmospheric particles in the South Pacific Ocean
An international team of marine biogeochemist and atmospheric scientists have made a rare discovery in the almost uncharted atmosphere of the South Pacific Ocean. They found that nocturnal nanoparticle bursts that contain nitrogenous compounds origin.....»»
Next-generation space telescopes could use deformable mirrors to image Earth-sized worlds
Observing distant objects is no easy task, thanks to our planet's thick and fluffy atmosphere. As light passes through the upper reaches of our atmosphere, it is refracted and distorted, making it much harder to discern objects at cosmological distan.....»»
