NASA has selected a fascinating new project for further development, known as the Diffractive Solar Sail. By bending light before it hits the sail, this device could propel spacecraft more efficiently than conventional propulsion technologies.

Since launching in February of 2020, the Solar Orbiter probe has been zeroing in on the Sun and has now used its advanced ultraviolet imager to capture the highest-resolution image ever of its outer atmosphere.

Scientists at Northeastern University have put an interesting new solution forward in the realm of UV monitoring – one that came about through a serendipitous discovery concerning the color-changing ways of camouflaging squid.

The Solar Orbiter spacecraft has captured a dramatic image of a giant eruption from the Sun. ESA says this solar prominence, which luckily wasn't pointing at Earth, is the largest ever observed with the full solar disk in a single image.

A new design for a solar-powered desalination device prevents the build-up of salt, making for an efficient and affordable system. Just four dollars' worth of materials should be enough for a device that can provide a family's daily drinking water.

In ice cores from both ends of the planet, scientists have discovered evidence of an extreme solar storm that struck Earth around 9,200 years ago, and strangely it seemed to have occurred during a period when the Sun should have been rather quiet.

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.
