Mercury, the planet nearest the sun, shares with Earth the distinction of being one of the two mountainous planets in the solar system with a global magnetic field that shields it from cosmic rays and the solar wind. Now ...
NASA has selected a new mission to study how the Sun generates and releases giant space weather storms—known as solar particle storms—into planetary space. Not only will such information improve understanding of how our solar ...
NASA has selected proposals for four missions that would study cosmic explosions and the debris they leave behind, as well as monitor how nearby stellar flares may affect the atmospheres of orbiting planets.
In February 2020, NASA's Solar Dynamics Observatory—SDO—is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the sun, studying how the sun creates solar activity and drives ...
Europe and NASA's Solar Orbiter rocketed into space Sunday night on an unprecedented mission to capture the first pictures of the sun's elusive poles.
A mission to study the interaction of the solar wind with the ancient cast-off winds of other stars, and the fundamental process of particle acceleration in space, has completed a critical NASA review and is now moving closer ...
Astrophysicists are redrawing the textbook image of pulsars, the dense, whirling remains of exploded stars, thanks to NASA's Neutron star Interior Composition Explorer (NICER), an X-ray telescope aboard the International ...
In August 2018, NASA's Parker Solar Probe launched to space, soon becoming the closest-ever spacecraft to the Sun. With cutting-edge scientific instruments to measure the environment around the spacecraft, Parker Solar Probe ...
The wind speed of a devastating Category 5 hurricane can top over 150 miles per hour (241km/hour.) Now imagine another kind of wind with an average speed of 0.87 million miles per hour (1.4 million km/hour.) Welcome to the ...
NASA launched a satellite on Thursday night to explore the mysterious, dynamic region where air meets space.
