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.
-
NASA and NOAA have confirmed that the Sun has entered a new solar cycle, with activity beginning to ramp back up from its minimum in December 2019. This next cycle is forecast to be rather quiet, continuing a long-term trend of reduced activity.
