Here’s what you’ll learn by reading this story: Scientists fired lasers at semiconductor nano-lasagna to show how electrons behave. In the right conditions, electrons become polarons, pulling oppositely charged atoms for a ride. The researchers took pictures of the newly born quasiparticle and measured its energy and mass. Scientists at Ludwig Maximilian University of Munich … Read more

A photon from a star billions of light-years away takes no time to reach a telescope. It’s not too little time. There is nothing. That result is not a measured or poetic way of speaking. It comes directly from the mathematics of special relativity, and it points to another strange thing about the nature of … Read more
For the first time, an astronomer has seen a comet change its speed and direction of rotation, thanks to a new analysis. The Hubble Telescope photos. The unexpected change is caused by “outgassing” jets that shoot an icy mixture of gas and dust into the solar system, according to a new study. Well, named 41P … Read more
Scientists have captured rare underwater footage of a whale giving birth, revealing a level of cooperation and support from nearby whales that researchers say has rarely been recorded in the wild. Video, recorded by the team of marine scientistsit not only shows the time of birth but also shows how other whales stayed close and … Read more

We may finally know what created the cosmic rhythms in the early Universe. According to information from the Hubble and James Webb Space Telescopes, the origin of free-flying photons in the early universe were small clusters of young stars that burst into life, removing the fog of smooth hydrogen that filled the interstellar space. A … Read more
