Scientists Use NASA Satellite Data to Track Ocean Microplastics from Space
The new technique relies on satellites that measure wind speed and ocean roughness
Key Building Block for Organic Molecules Discovered in Meteorites
While commonly associated with life, organic molecules also can be created by non-biological processes and are not necessarily indicators of life
Is There a Missing Ingredient in Dark Matter Theories?
Researchers have uncovered a discrepancy between the theoretical models of how dark matter should be distributed in galaxy clusters, and observations of dark matter's grip on clusters
NASA Missions Explore a 'TIE Fighter' Active Galaxy
Galaxy's appearance at different radio frequencies helps scientists learn more about how active galaxies can change dramatically on decade time scales
New 3D View of Methane Tracks Sources
Combining multiple data sets from emissions inventories into a high-resolution computer model, researchers now have an additional tool for understanding this complex gas
NASA Planet Hunter Finds Its First Earth-Size Habitable-Zone World
Scientists confirmed the find, called TOI 700 d, using NASA's Spitzer Space Telescope and have modeled the planet's potential environments to help inform future observations
With Mars Methane Mystery Unsolved, Curiosity Serves Scientists a New One: Oxygen
On Mars, oxygen behaves in a way that so far scientists cannot explain through any known chemical processes
Pressure Runs High at Edge of Solar System
This pressure was recently measured by scientists in totality for the first time—and it was found to be greater than expected
Satellite Data Record Shows Climate Change's Impact on Fires
In 2019, wildfires have already burned 2.5 million acres in Alaska in an extreme fire season driven by high temperatures, which have also led to massive fires in Siberia
