(CNN) The Hubble Space Telescope has captured images of glowing auroras over Jupiter just days before NASA's new Juno spaceship arrives to orbit the gas giant. "These auroras are very dramatic and among the most active I have ever seen," said Jonathan Nichols from the University of Leicester, UK, and principal investigator of the study. "It almost seems as if Jupiter is throwing a fireworks party for the imminent arrival of Juno," Nichols said in press release. The new Hubble images show bluish lights that appear to dance over Jupiter's poles. NASA says the observations of the auroras were supported by measurements made by Juno, which starts orbiting Jupiter on Monday, July 4.
