<p></p> <p>For a planet, this would be like a day at the spa. After years of growing old, a massive planet could, in theory, brighten up with a radiant, youthful glow.

<p style="text-align: center;"></p> <p>Supernovas are often thought of as the tremendous explosions that mark the ends of massive stars’ lives. While this is true, not all supernovas occur in this fashion.

<p>NASA’s Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded
