Cosmic Rays Could Be the Key to Unlocking the Mysteries of the Universe
Cosmic rays are high-energy particles that travel through space at nearly the speed of light. They originate from various sources, such as supernova explosions, active galactic nuclei, and gamma-ray bursts. Some of them are so powerful that they can reach energies of over a quadrillion electron volts (PeV), which is...
Plants may be able to absorb more CO2 than expected, new study suggests
A new study published in the journal Science Advances has revealed that plants may be able to take up more carbon dioxide (CO2) from human activities than previously thought. The study, led by Dr. Jürgen Knauer from Western Sydney University, used a more realistic ecological model that accounted for some...
NASA Achieves First-Ever Laser Communication from Deep Space
NASA’s Deep Space Optical Communications (DSOC) experiment has successfully transmitted data via laser from nearly 10 million miles (16 million kilometers) away, setting a new record for optical communication in space. The experiment, which is part of the Psyche mission to explore a metallic asteroid, aims to demonstrate the potential...
NASA’s Artemis II Astronauts Get a Close Look at the SLS Rocket Core Stage
