Earth is immersed in material streaming from the Sun. This stream, called the solar wind, is washing over our planet, causing breathtaking auroras, impacting

From space weather to science missions, there's a lot to be excited about in heliophysics this year.

The science of the sun and its effects on the solar system is a sprawling discipline that expects a very exciting 2025

From a death swirl into Jupiter to "Ghost Riders in the Sky," here are some of the most exciting space missions coming in 2025.

Astronomers have discovered a transiting exoplanet -- named IRAS 04125+2902b -- orbiting a 3-million-year-old, 0.7-solar-mass protostar in the Taurus Molecular Cloud.

Another in a series of unusually strong solar storms hitting Earth produced stunning skies full of pinks, purples, greens and blues farther south than normal, including into parts of Germany, the United Kingdom, New England and New York City.

There is a profound mystery in our sun. While the sun's surface temperature measures around 10,000 degrees Fahrenheit, its outer atmosphere, known as the solar corona, measures more like 2 million degrees Fahrenheit, about 200 times hotter.

Combined data from ESA and NASA has demonstrated how fluctuations in the sun's magnetic field accelerate and heat the solar wind. The post Probes see fast solar wind getting a magnetic shove first appeared on EarthSky.

Scientists analyzed famed astronomer Johannes Kepler's 1607 sketches of sunspots to solve a mystery about the sun's solar cycle that has persisted for...

NASA's Parker Solar Probe has found news clues in the longstanding mystery of why the sun's outer atmosphere, or corona, is so much hotter than our star's surface.

A new weather satellite will monitor both Earth and space-based weather. The GOES-U mission will gauge storm severity on Earth and track solar storms.

The U.S. National Oceanic and Atmospheric Administration issued a rare severe geomagnetic storm warning when a solar outburst reached Earth on Friday afternoon, hours sooner than anticipated.

Coronal moss grows, solar rain falls and plasma eruptions rear their gargantuan heads in this fiery landscape of the sun's outer atmosphere, taken by ESA's Solar Orbiter.

Some stars erupt with 'superflares' 10,000 times as powerful as solar flares from the sun. A team of "stellar detectives" are on the case and may now know...

The total solar eclipse on April 8 plunged Syracuse, New York's Milton J. Rubenstein Museum of Science & Technology into darkness for 90 seconds, creating a wondrous and memorable totality.

Maps outlining the solar eclipse's path of totality may not be exact — and no one can be certain. NASA advises moving as close to the path's center as...
