About six gigatons -- roughly 12 times the mass of all living humans -- of carbon appears to be emitted over land every year, according to data from the Chinese Global Carbon Dioxide Monitoring Scientific Experimental Satellite (TanSat).
Little is known about the weather at night on Venus as the absence of sunlight makes imaging difficult. Now, researchers have devised a way to use infrared sensors on board the Venus orbiter Akatsuki to reveal the first details of the nighttime weather of our nearest neighbor. Their analytical methods could be used to study other planets including Mars and gas giants as well.
Traces of the gas phosphine point to volcanic activity on Venus, according to new research from Cornell University.
Scientists have used data from the Southwest Research Institute-led Magnetospheric Multiscale (MMS) mission to explain the presence of energetic heavy elements in galactic cosmic rays (GCRs). GCRs are composed of fast-moving energetic particles, mostly hydrogen ions called protons, the lightest and most abundant elements in the universe. Scientists have long debated how trace amounts of heavy ions in GCRs are accelerated.
Scientists knew a burst of UV light left its mark on our solar system. Now they know the source of that light.
New research highlights the importance of understanding sea surface temperatures patterns in predicting future hurricane frequency.
Meteorites that do not experience high temperatures at any point in their existence provide a good record of complex chemistry present when or before our solar system was formed. So researchers have examined individual amino acids in these meteorites, many of which are not in present-day organisms. In Physics of Fluids, researchers show the existence of a systematic group of amino acid polymers across several members of the oldest meteorite class, the CV3 type.
California's old-growth blue oak woodlands are dying off, shows a new study by the open access publisher Frontiers. The authors use a new approach to show that heat, drought and wildfires are the all contributing to the loss and deterioration of these native ecosystems. The study focuses on the extreme drought of 2012-2016, but suggests that these conditions will become more frequent in the future.
Ozone levels in the earth's troposphere (the lowest level of our atmosphere) can now be forecasted with accuracy up to two weeks in advance, a remarkable improvement over current systems that can accurately predict ozone levels only three days ahead. The new artificial intelligence system developed in the University of Houston's Air Quality Forecasting and Modeling Lab could lead to improved ways to control high ozone problems and even contribute to solutions for climate change issues.
Solar activities, such as CME(Coronal Mass Ejection), cause geomagnetic storm that is a temporary disturbance of the Earth's magnetosphere. Geomagnetic storms can affect GPS positioning, radio communication, and power transmission system. Solar explosions also emit radiation, which can affect satellite failures, radiation exposure to aircraft crew, and space activity. Therefore, it is important to understand space weather phenomena and their impact on the Earth.
