Roughly every 11 years, at the height of the solar cycle, the Sun’s magnetic poles flip — on Earth, that’d be like the North and South Poles swapping places every decade — and the Sun transitions from sluggish to active and stormy.During the most active part of the cycle, known as solar maximum, the Sun can unleash immense explosions of light, energy, and solar radiation — all of which create conditions known as space weather. Space weather can affect satellites and astronauts in space, as well as communications systems — such as radio and GPS — and power grids on Earth. When the Sun is most active, space weather events become more frequent.

Launching in 2018, Parker Solar Probe will provide new data on solar activity and make critical contributions to our ability to forecast major space-weather events that impact life on Earth.In order to unlock the mysteries of the corona, but also to protect a society that is increasingly dependent on technology from the threats of space weather, we will send Parker Solar Probe to touch the Sun.In 2017, the mission was renamed for Eugene Parker, the S. Chandrasekhar Distinguished Service Professor Emeritus, Department of Astronomy and Astrophysics at the University of Chicago. In the 1950s, Parker proposed a number of concepts about how stars—including our Sun—give off energy. He called this cascade of energy the solar wind, and he described an entire complex system of plasmas, magnetic fields, and energetic particles that make up this phenomenon. Parker also theorized an explanation for the superheated solar atmosphere, the corona, which is – contrary to what was expected by physics laws -- hotter than the surface of the sun itself.

In humans, large doses of radiation can damage DNA and harm bodily tissue. To help ensure the safety of airline passengers and crew, a NASA-funded project called NAIRAS (Nowcast of Atmospheric Ionizing Radiation System) has modeled the impact of space weather on radiation levels in the atmosphere with up-to-the-hour accuracy.

Five decades later, scientists are still trying to unlock the mysteries of these phenomena known as the Van Allen Belts. As solar wind and cosmic rays carry fast-moving, highly energized particles past Earth, scientists think some of these particles become trapped by the planet's magnetic field. The resulting belts, one inner and one outer, can swell or shrink in size in response to incoming particles from Earth's upper atmosphere and changes in the solar wind. But sometimes the belts don't change when scientists expect them to. New NASA spacecraft scheduled to launch in August 2012 seek to determine what kinds of solar outbursts and other space weather cause specific changes in the radiation belts—answering some of the questions first raised decades ago.

Within minutes of the eruption, solar particles swirled into the Earth's magnetosphere—the protective envelope that shields our planet from the sun's powerful rays. Dazzling auroras electrified the night sky as the coronal mass ejection raced behind the flare at almost 1,400 miles per second and hit Earth within 36 hours.

The solar wind shoots out from the sun until it pushes up against the galactic medium and slows down at a line called the termination shock. Beyond this lies the heliosheath, where the solar wind's journey stops completely. Scientists thought the solar wind turned back smoothly at this point, sweeping back around the outskirts of the solar system.

Crossing the globe, visualizations trace North America's East Coast and ocean currents in the North Atlantic Ocean. The lights of the world's cities then show human impact. Next, two models probe nearby-space phenomena, fluid behavior in microgravity conditions and an asteroid collision. A jaunt to Mars explores the mountains and trenches of its dry, rocky exterior. The video concludes at a binary neutron star system, where two city-sized objects with the Sun's mass merge in a titanic explosion. || ", "hits": 76 }, { "id": 90, "url": "https://svs.gsfc.nasa.gov/90/", "result_type": "Visualization", "release_date": "1995-11-07T12:00:00-05:00", "title": "SAMPEX - Yohkoh: Solar Modification of Relativistic Electrons in the Earth's Radiation Belts", "description": "The Solar Anomalous and Magnetospheric Particle Explorer, SAMPEX, measures fluxes of energetic particles from the sun, the Earth's magnetosphere, and cosmic ray sources over a broad range of energies.
