Next generation of greenhouses may be fully solar powered

Many greenhouses could become energy neutral by using see-through solar panels to harvest energy — primarily from the wavelengths of light that plants don’t use for photosynthesis. Those are the findings of a new modeling study conducted by engineering, plant biology and physics researchers at North Carolina State University.advertisement “Plants only use some wavelengths of […]

Solar power from ‘the dark side’ unlocked by a new formula

Solar panels mounted on ground (stock image).Credit: © liptakrobi / Adobe Stock Most of today’s solar panels capture sunlight and convert it to electricity only from the side facing the sky. If the dark underside of a solar panel could also convert sunlight reflected off the ground, even more electricity might be generated.advertisement Double-sided solar cells […]

First identified comet to visit our solar system from another star

Comet 2I/Borisov is only the second interstellar object known to have passed through the solar system. These two images, taken by NASA’s Hubble Space Telescope, capture the comet appearing near a background galaxy (left) and soon after its closest approach to the Sun (right).Credit: NASA, ESA, and D. Jewitt (UCLA) When astronomers see something in […]

NASA’s Parker Solar Probe sheds new light on the sun

In August 2018, NASA’s Parker Solar Probe launched to space, soon becoming the closest-ever spacecraft to the Sun. With cutting-edge scientific instruments to measure the environment around the spacecraft, Parker Solar Probe has completed three of 24 planned passes through never-before-explored parts of the Sun’s atmosphere, the corona. On Dec. 4, 2019, four new papers […]
