In the race to make solar energy cheaper and more efficient, a team of UNSW Sydney scientists and engineers have found a way to push past one of the biggest limits in renewable technology.

Singlet fission is a process where a single particle of light—a photon—can be split into two packets of energy, effectively doubling the electrical output when applied to technologies harnessing the sun.

In a study appearing in ACS Energy Letters , the UNSW team—known as “Omega Silicon”—showed how this works on an organic material that could one day be mass-produced specifically for use with solar panels.

“A lot of the energy from light in...

An interstellar comet that originated outside our solar system has just made its closest pass to the sun, brightening dramatically and rapidly as it did so. The reason for the sudden extreme activity is currently puzzling scientists.

As more and more exoplanets are discovered throughout the galaxy, scientists find some that defy explanation—at least for awhile. A new study, published in Nature, describes a process that might explain why a large portion of exoplanets have water on their surface, even when it doesn’t make sense.

Water where it shouldn’t be
A particular category of exoplanets that are between the size of Earth and Neptune, referred to as “sub-Neptunes,” generally have a rocky core, which is surrounded by an envelope of either hydrogen or water...

This new NASA/ESA/CSA James Webb Space Telescope Picture of the Month features a cosmic creepy-crawly called NGC6537—the Red Spider Nebula. Using its Near-InfraRed Camera (NIRCam), Webb has revealed never-before-seen details in this picturesque planetary nebula with a rich backdrop of thousands of stars.

Planetary ne...
