Here on Earth, people are gearing up for Halloween with pumpkin carvings, costume shopping and candy cravings, and it seems our Sun wants in on the fun, too. NASA has just released photos of the Sun and its active regions, looking eerily like a toothy grin on a jack-o-lantern's face.
NASA has identified a massive patch of darkness snaking across the surface of the Sun. But don't worry, a giant space-snake has not made its new home so close to Earth. NASA's Solar Dynamics Observatory (SDO) has identified it as an unusually massive and long filament of solar material that is some one million miles across, from end to end.
Most of the water found in our solar system, Earth included, is older than the Sun, likely originating as ices that formed in interstellar space, according to new research.
Things are stirring up around a T Tauri star, the infant equivalent of our own Sun, as astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around the small solar system.
The Sun's "brightpoints" serve as new markers for determining the mysterious and ever-changing solar cycle of our closest star, according to a new study, changing scientists' previous beliefs about what drives this cycle.
Located in the heart of the Sun, physicists have for the first time directly detected neutrinos, revealing a little about our closest star and the sources of its energy, a new study describes.
Astrophysicists have a very general and extremely theoretical idea of what happened after the Big Bang, including the formation of our solar system's Sun and stars like it. However, a team of experts from Monash University now believe that they have discovered something that will take us a step closer to understanding what the Sun's birth was truly like.
A stellar nursery that produced our solar system formed 30 million years before the birth of the Sun, revealing details about the events leading up to the Sun's debut, according to a new study.
The Sun's outer atmosphere is hotter than its surface, and scientists have just pinned nanoflares as the reason behind this mysterious extra heat, according to a new study.
Earlier this month, NASA's Jet Propulsion Laboratory (JPL) confirmed that the unmanned spacecraft Voyager1 has slipped into interstellar space - a first for a manmade observational tool. However, researchers are now refuting this claim, saying that we won't truly know if this spacecraft has gone interstellar until late 2015.
Researchers have recently identified a portion of a prolific stellar nursery which has chemical signatures that would indicate a cold environment utterly impossible for its location. These signatures they say, could be explained by an unusual burst of stellar winds.
NASA scientists have discovered that the atmosphere of the Sun is even larger than thought, reaching out an estimated 5 million miles above the star's surface.
Last year, sun-watching spacecraft spotted a series of unusually slow eruptions on the surface of the Sun that the space agency has described as almost "reluctant." Now researchers have determined some of the factors that can cause such a slow eruption to occur.
NASA's Solar Dynamics Observatory caught two incredible solar flares on film from start to finish on Tuesday, reminding researchers why they study these mysterious but stunning phenomena.
