Visualization of the HESS telescope array capturing the showers of particles that can be produced by high-energy cosmic electrons, positrons, and gamma rays. © MPIK / H.E.S.S. Collaboration Using a telescope in Namibia, astronomers and physicists have discovered extremely energetic electrons among the continuous rain of cosmic rays, the charged particles (mostly protons and electrons) […]
Astronomers have used the Hubble and James Webb space telescopes to gain an unprecedentedly clear view of the disk of gas and dust surrounding the star Vega. There’s no sign of large planets orbiting within it, forcing astronomers to reconsider the range of possible disk architectures and how common planetary systems like the solar system […]
Using the CHIME radio telescope, astronomers detected a three-second flash from a far-off galaxy that contained beat with a surprising regularity.
