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
Hubble Uncovers Black Hole That Shouldn't Exist
The unexpected presence of a disk of material so close to a black hole offers a unique opportunity to test Albert Einstein's theories of relativity
NASA Helps Warn of Harmful Algal Blooms in Lakes, Reservoirs
With limited resources to monitor these often-unpredictable blooms, water managers are turning to new technologies from NASA and its partners to detect and keep track of potential hazards
NASA Finds Possible Second Impact Crater Under Greenland Ice
If the second crater is confirmed as the result of a meteorite impact, it will be the 22nd largest impact crater found on Earth
