Green glow or not, you will always have a first-row seat for Mars with our app Redshift Sky (available for iOS and Android). But there still needs to be a lot of research done on the behavior of oxygen.

The green glow around Mars seems to stem from oxygen atoms as well and has been predicted already 40 years ago. You can only see it from an вЂњedge onвЂќ perspective вЂ“ when you look at Earth from the ISS, for example. This glow is quite unusual only Earth has something similar called night glow, which occurs because oxygen atoms emit a certain wavelength of light. WhatвЂ™s green, on Mars, but not a Martian?Д®SAвЂ™s ExoMars Trace Gas Orbiter recently found a green glow in the atmosphere around Mars. #fact #facts #didyouknow #science #instafacts #dailyfacts #scientist #knowledge #dailyfact #interestingfacts #knowledgeispower #factzonly #photographylovers #telescope #outerspace #astronomy #spacetime #astronaut #spacegirl #spacecraft #universe #astrology #nasa #space #spaceexploration #hubble #cosmos #galaxy #flatearth #interstellar. If you prefer to see aphelions and perihelions of other planets in the solar system, head on over to our app Redshift Sky. And if you want to talk about both points, itвЂ™s called apsis (plural apsides). Oh, and the farthest point would be called respectively aphelion or apastron. If you wanted to talk about the nearest point of an objectвЂ™s orbit around another sun, it would be called periastron (obviously). Peri means вЂњnearвЂќ, -helion refers to our sun. The closest point of a bodyвЂ™s direct orbit around the sun is called perihelion.

This time, we will brush up your Ancient Greek skills. We love teaching you about all things in space рџЊЊ.
