'There's just enough atomic oxygen at the top of Mars' atmosphere to appear the same color as green aurora on Earth,' physicist Nick Schneider said.
A massive explosion on the surface of the sun is expected to cause auroras on Mars, and they will look nothing like the northern and southern lights we see on Earth.Sunspot AR3738, a huge and volatile sunspot on the sun's surface, just spat out a powerful X1.9-class solar flare on July 16, sending a plume of solar plasma shooting out into space.
Mars is much smaller than Earth, so its interior has already cooled off and it can't create a magnetic field,' Nick Schneider of the University of Colorado's Laboratory for Atmospheric and Space Physics , previously told Newsweek.Mars can therefore experience auroras not just at its poles like Earth, but across the entirety of the planet, as the solar particles in a CME can collide with its sparse atmosphere all at once.
