New method minimizes alignment errors in microlens array production

Double-sided microlens arrays (DSMLAs) play a crucial role in improving the performance of optical devices, supporting applications from advanced imaging systems to laser beam homogenization. However, traditional manufacturing methods often struggle with alignment errors that diminish the functionality and efficiency of these arrays.

Could alien solar panels be technosignatures?

If alien technological civilizations exist, they almost certainly use solar energy. Along with wind, it’s the cleanest, most accessible form of energy, at least here on Earth. Driven by technological advances and mass production, solar energy on Earth is expanding rapidly.

Finding the age of a contact binary ‘moon’

There are millions of asteroids floating around the solar system. With so many of them, it should be no surprise that some are weirdly configured. A recent example of one of these weird configurations was discovered when Lucy, NASA’s mission to the Trojan asteroids, passed by a main-belt asteroid called Dinkinesh.

Maybe ultra-hot Jupiters aren’t so doomed after all

Ultra-hot Jupiters (UHJs) are some of the most fascinating astronomical objects in the cosmos, classified as having orbital periods of less than approximately three days with dayside temperatures exceeding 1,930°C (3,500°F), as most are tidally locked with their parent stars.

New discoveries about the nature of light could improve methods for heating fusion plasma

Both literally and figuratively, light pervades the world. It banishes darkness, conveys telecommunications signals between continents and makes visible the invisible, from faraway galaxies to the smallest bacterium. Light can also help heat the plasma within ring-shaped devices known as tokamaks as scientists worldwide strive to harness the fusion process to generate green electricity.
