\n Mars is known as the Red Planet due to its coppery hue. It\u2019s a dry, dusty, windy place, but that wasn\u2019t always the case. The planet was once very, very wet, with vast rivers and lakes dotting its surface. If life took root there in the distant past, it may have even been green with life.<\/p>\n

Researchers writing in the journal Nature Astronomy report that Mars is once again green, but not because it\u2019s suddenly sprouted lush plant life. It\u2019s actually the thin atmosphere of the planet that has taken on a green glow as observed by the Trace Gas Orbiter which currently calls Mars home.<\/p>\n

Residents of certain parts of planet Earth are occasionally treated to some pretty spectacular light shows in the night sky. The Northern Lights (or Southern Lights, depending on which end of the globe you\u2019re on), are a well-known and often-studied phenomenon. On Earth, the streaks of green, blue, and other colors in the sky are a byproduct of our planet\u2019s magnetic field channeling energized particles.<\/p>\n

The glow that the TGO is seeing on Mars is an entirely different phenomenon, but it\u2019s not unique to the Red Planet. Mars doesn\u2019t have a strong magnetic field like Earth does, but it does have oxygen in its atmosphere. Those oxygen atoms get charged up by sunlight and then when they relax, they glow a pale shade of green.<\/p>\n

Astronauts have observed this happening around Earth, and to see it on Mars isn\u2019t necessarily surprising, but it does offer researchers some information about the planet\u2019s atmosphere.<\/p>\n

\u201cBy looking at the altitudes of where this emission is, you can actually tell the thickness of the atmosphere and how it\u2019s varying,\u201d Dr. Manish Patel, co-author of the study, said in a statement. \u201cSo, if you were to keep observing this phenomenon, you could see the height of the atmosphere change, something it does for example when it heats up during dust storms. This is an issue we face when we try to land on Mars because we\u2019re never quite sure just how thick the atmosphere will be when we plough through it to get to the surface.\u201d<\/p>\n

Knowing the position and thickness of the atmosphere is important when you\u2019re travel<\/a>ing to a new world, as it affects the angle of approach that a spacecraft would need to take to avoid damage or skipping off into space. NASA and other space agencies have already made it clear that they plan on sending humans to Mars in the not-so-distant future, so this information could come in handy.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
