The curling waves of the Kelvin-Helmholtz instability – appearing briefly in the center of the image before dissipating – may explain how gases mix in otherwise stable layers of the atmosphere.
The Stratospheric Observatory for Infrared Astronomy examined several types of pulsating stars in our Milky Way galaxy, watching as some spewed carbon, a key ingredient of life as we know it, into interstellar space.
NASA’s Lucy mission's critical components, and subsystems, scientific instrumentation, electrical and communication systems, and navigation systems are coming together.
Using data from NASA’s Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun’s biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense... Read More
NASA's Mars 2020 Perseverance rover mission is on its way to the Red Planet to search for signs of ancient life and collect samples to send back to Earth.
In a Q&A, spacesuit designer Amy Ross explains how five samples, including a piece of helmet visor, will be tested aboard the rover, which is targeting a July 30 launch.

NASA will host a media teleconference at 4:30 p.m. EDT Thursday, July 16, to provide an update on the status of the agency’s James Webb Space Telescope, the world’s next premier infrared space observatory and the largest, most complex space telescope for astronomy ever built.
As of June 2020, NASA’s Solar Dynamics Observatory — SDO — has now been watching the Sun non-stop for over a full decade. From its orbit in space around the Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This... Read More
