After setting off back in 2018 on a history-making mission to study the Sun by getting up close and personal with its atmosphere, NASA's Solar Parker Probe has finally entered this region area for the first time.

A rarely seen total eclipse of the Sun in Antarctica on December 4 is drawing the attention of an international partnership of scientists who hope to learn more about the effects of such eclipses on space weather.

NASA's Parker Solar Probe has set a new pair of records after it survived its 10th close encounter with the Sun, coming within 5.3 million miles of the surface and reaching a speed of 363,660 mph, making it the fastest-ever artificial object.

Last year, physicists reported that an experimental dark matter detector picked up a strange signal. A new Cambridge study suggests it could be the first direct detection of dark energy, the mysterious force accelerating the expansion of the universe.

Mercury’s disproportionately massive core may be the result of the Sun’s powerful magnetic influence rather than the consequence of a cataclysmic collision with another body in the ancient past, according to the results of a new study.

A new study has revealed that crewed missions launching to Earth’s moon and beyond may soon be facing a new challenge. Just five years from now, such ventures could be at an increased risk of extreme space weather events emanating from the Sun.

More than 40 years after launch, Voyager 1 is still making new discoveries. The latest achievement by the craft is the detection of a faint, plasma “hum,” indicating that there may be more activity in interstellar gas than previously thought.

NASA's Parker Solar Probe continues to edge closer and closer to its target, setting one new record after another. The latest came during a close approach today, where the spacecraft exceeded blistering speeds of 330,000 mph (532,000 km/h).

Scientists have made a breakthrough in the way we study this plasma, managing to trap an ultracold form of it in a magnetic "bottle" for the first time, an achievement that could act as a springboard for research into nuclear fusion energy.

Astronomers have released a stunningly detailed image captured by the by the Daniel K. Inouye Solar Telescope, revealing the structure of a massive sunspot as it temporarily darkened the Sun’s surface on January 28, 2020.

Scientists have condensed decades of footage taken of our Sun’s atmosphere into a 47-minute video showcasing solar activity on a grand scale. The video was released to mark the 25th anniversary of the NASA/ESA Solar and Heliospheric observatory.

Borexino, a huge underground particle detector in Italy, has picked up a never-before-seen type of neutrino coming from the Sun. These neutrinos confirm a 90-year-old hypothesis and complete our picture of the fusion cycle of the Sun and other stars.
