View Full Version : X-Ray Portrait of Proxima Centauri

SUMMARY: NASA's Chandra X-Ray Observatory took this image of red dwarf star Proxima Centauri, our closest stellar neighbour (after the Sun, of course). The image shows that its surface is in a constant state of turmoil, with flares occurring almost continuously. Proxima Centauri has only 1/10th the mass of our own Sun, and the conversion of hydrogen to helium happens much more slowly. This creates turbulent, convective motion throughout its interior, which stores up magnetic energy - the energy is what creates all the flares.
