This artist’s concept illustrates a catastrophic collision between two rocky exoplanets in the planetary system BD +20 307, turning both into dusty debris. Ten years ago, scientists speculated that the warm dust in this system was a result of a planet-to-planet collision. Now, NASA's SOFIA mission found even more warm dust, further supporting that two rocky exoplanets collided. This helps build a more complete picture of our own solar system’s history. Such a collision could be similar to the type of catastrophic event that ultimately created our Moon.
The greater sage-grouse, also known as the sagehen, is the largest grouse in North America. Its range is sagebrush country in the western United States and southern Alberta and Saskatchewan, Canada. It was known as simply the sage grouse until the Gunnison sage-grouse was recognized as a separate species in 2000.
Developed for a NASA project, the soft sheets full of high-tech gear can turn almost anything into a versatile automaton.
When NASA put out a call for soft robotic technologies, Rebecca Kramer-Bottiglio and her team at Yale University replied with something remarkable: robotic skins that can wrap around everyday objects, turning almost anything into a moving, grasping robot.
The National Solar Observatory has captured the highest resolution video ever of the Sun's surface.
Each of the visible "cell-like structures" is about the size of Texas, NSO says
