😀 But at least you will have time to check out our app Redshift Sky. We guarantee you that you won’t have a second date afterward. You can add also that it shouldn’t be mistaken with a meteorite: that is a solid piece of debris that falls to the Earth’s surface. You can earn extra points by pointing out that meteors are only the visible streak of light, while a meteoroid is a small object that is travelling though outer space. In case you two are lucky, he/she will say: “Look, a shooting star!” Then correct them by saying: “Shooting stars are no stars, they’re meteors.” Because stars are luminous spheroid of plasma. Want to ruin a perfectly good date? Here’s a good way how: Go stargazing. #alien #greenglow #fact #facts #science #instafacts #dailyfacts #scientist #dailyfact #interestingfacts #knowledgeispower #factzonly #ceeling #photographylovers #photographylife #telescope #outerspace #astronomy #spacetravel #spacecraft #astrophysics #universe #spaceexploration #nasa #universe #galaxy #photography #astrophotography #astronaut #spacelove. 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 “edge on” perspective – 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. What’s green, on Mars, but not a Martian?ĮSA’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, it’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 object’s orbit around another sun, it would be called periastron (obviously). Peri means “near”, -helion refers to our sun. The closest point of a body’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 🌌.
