Like Earth, Jupiter's magnetic field channels electrically charged particles into its atmosphere, resulting in the formation of brilliant aurorae near its poles. However, the brightness and variety of Jupiter's auroral emissions exceed those generated on our planet. Of particular interest are patches of emission that originate from even closer to the poles than the main aurorae, a feature that appears far stronger at Jupiter than at Earth or Saturn.

In 1977, NASA created two LP records with tracks of global music, greetings in different languages, sounds of the planet, and sonified images, and then attached them to the two robotic probes launched that year as part of the Voyager space mission bound for the outer solar system and beyond. This Golden Record, said Alexander Rehding, Fanny Peabody Professor of Music, is "effectively a mixtape for extraterrestrial civilizations, a sign that we exist and a glimpse of what human culture is about.

The night sky is going to get much busier thanks to thousands of new internet satellites set to launch over the next few years—and researchers say it's going to affect Canada more than most places on Earth.

Researchers from the University of Toronto, the University of Regina and the University of British Columbia found that most light pollution is expected to happen near 50 degrees latitude north and south due to the orbits of the new satellites.
