Invisible"global auroras" have been covering Mars frequently over the past few months, according to data collected by a NASA spacecraft. The rise in these planet-wide light shows, including an unprecedented"aurora hat trick" in February, is tied to solar maximum, the peak in the sun's roughly 11-year solar cycle.
In recent months, the number of global auroras and other auroral activity have risen significantly, Spaceweather.com reported. Mars is not the only planet other than Earth to have auroras. Similar light shows have been spotted on Mercury, Jupiter, Saturn and Uranus, according to Live Science's sister site Space.com. Last year, scientists also spotted aurora-like phenomena on the sun for the first time.
