Mars has unveiled its captivating secret as scientists reveal the mesmerizing green glow that illuminates the planet during the night.
The Martian atmosphere has revealed a new discovery thanks to ESA's ExoMars Trace Gas Orbiter. The mission has detected a green nightglow, which is different from auroras, and provides valuable information on atmospheric processes. This finding is a significant step forward in our understanding of Mars and could potentially aid future missions to the planet. The nightglow could also serve as a source of illumination for astronauts and rovers exploring the polar regions of Mars. This phenomenon occurs when two oxygen atoms combine to form an oxygen molecule, emitting light at lower altitudes.
The Martian nightglow is believed to be caused by a process in which carbon dioxide molecules in the planet's atmosphere are split into carbon monoxide and oxygen atoms when exposed to solar ultraviolet radiation above an altitude of 70 km. These oxygen atoms are then transported by a Hadley cell to high winter latitudes, where they recombine into molecular oxygen, emitting infrared radiation at an altitude of 30-50 km. The resulting emission is responsible for the nightglow observed on Mars. The discovery of this phenomenon is unexpected and interesting for future missions to the Red Planet.
Airglow is a natural phenomenon that occurs in Earth's atmosphere when sunlight interacts with atoms and molecules. Astronauts aboard the International Space Station captured an image in 2011 that shows a green band of oxygen glow over Earth's curve. The image also reveals portions of northern Africa, with evening lights shining along the Nile River and its delta. This stunning image was credited to NASA.
ESA's ExoMars Trace Gas Orbiter has captured an artist's depiction of the green glow of oxygen in the martian atmosphere. This fascinating emission, resembling the night glow observed around Earth's atmosphere from space, was detected on the dayside of Mars. The Trace Gas Orbiter, positioned at an altitude of 400 km above the Red Planet, utilized the NOMAD instrument's ultraviolet-visible channel to monitor the night side of Mars. This instrument, developed by the Royal Belgian Institute for Space Aeronomy in collaboration with teams from Spain, Italy, the United Kingdom, and others, covers a wide spectral range from near ultraviolet to red light. By focusing on the edge of Mars, the NOMAD experiment aims to gain a better understanding of the upper atmosphere.
The scientific value of studying the nightglow lies in its ability to serve as a tracer for atmospheric processes. It offers valuable insights into the composition, dynamics, and oxygen density of a region of the atmosphere that is challenging to measure. Additionally, it provides information on how energy from both the Sun's light and the solar wind, a stream of charged particles originating from our star, is deposited in the Martian atmosphere.

In 2015, NASA astronaut Scott Kelly captured an image of the Milky Way and Earth together beyond the International Space Station. The photo shows the Milky Way below the curve of Earth's limb, with a faint green airglow visible. The galaxy's central bulge is also visible, with starfields cut by dark rifts of obscuring interstellar dust. This snapshot from space is a stunning reminder of the beauty of our universe. Credit goes to NASA and Scott Kelly for this incredible image.
Understanding the properties of Mars' atmosphere is crucial for missions to the Red Planet's surface. The density of the atmosphere affects the drag experienced by orbiting satellites and the parachutes used to deliver probes to the Martian surface. Nightglow, a phenomenon observed on Earth and Mars, is often confused with auroras. However, auroras are just one way in which planetary atmospheres light up. Nightglow is more homogeneous and exhibits a wide range of colors depending on atmospheric gases. The green nightglow on Earth is best seen from an 'edge on' perspective, as shown in images taken by astronauts from the International Space Station.
During his six-month Principia mission on the International Space Station, European Space Agency astronaut Tim Peake captured a timelapse video. In this video, Peake showcases the mesmerizing view of an 'aurora rise' from the International Space Station, and he also points out the presence of two satellites at the end. The timelapse was created by compiling images taken at one-second intervals and playing them back 25 times faster. This incredible footage provides a unique perspective of the Earth's beauty from space. Credit for the video goes to ESA/NASA.
