(Image credit: NASA/SDO/GSFC) SAN FRANCISCO — The sun's current space-weather cycle is the most anemic in 100 years, scientists say. Our star is now at "solar maximum," the peak phase of its 11-year activity cycle. But this solar max is weak, and the overall current cycle, known...

Recently, the NASASun Twitter handle shared an image of the sun seemingly ‘smiling’. Captured by the NASA Solar Dynamics Observatory, the image has dark patches on the sun’s surface resembling eyes and a smile. NASA explained that the patches are called coronal holes, which can be seen...
For low latitudes, we examined the sensitivity of the resulted ROTI maps to detect plasma irregularities associated with equatorial plasma bubbles development for low, middle, and high solar activity periods.doi:10.3390/s22103748Cherniak IuriiZakharenkova Irina...
The radiation risk for astronauts in long space flights depends on the impact of low-intensity galactic and solar radiation on the spaceship. There is a sm
According to the paper [53], NASA has recently established the “Starlight” program, which basic assumption is to develop a small, interstellar unit to be send outside our solar system. NASA conceptual roadmap aims at both robotic space exploration and in-depth characterization of well-known ...
NASA's and ESA's Planetary Protection offices ensure responsible exploration of the solar system and aim at avoiding inadvertent contamination of celestial bodies with biomolecules or even living organisms. Life forms that have the potential to colonize foreign planetary bodies could be a threat to ...
