Bienvenue sur « Redshift live », le site communautaire du planétarium virtuel Redshift! 1 month ago Chronik-Fotos We love teaching you about all things in space 🌌. This time, we will brush up your Ancient Greek skills. Ready? 🤓 The closest point of a body’s direct orbit around the sun is called perihelion. Peri means “near”, -helion refers to our sun. If you wanted to talk about the nearest point of an object’s orbit around another sun, it would be called periastron (obviously). Oh, and the farthest point would be called respectively aphelion or apastron. And if you want to talk about both points, it’s called apsis (plural apsides). If you prefer to see aphelions and perihelions of other planets in the solar system, head on over to our app Redshift Sky. #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 ...

ESA’s ExoMars Trace Gas Orbiter recently found a green glow in the atmosphere around Mars. This glow is quite unusual; only Earth has something similar called night glow, which occurs because oxygen atoms emit a certain wavelength of light. You can only see it from an “edge on” perspective – when you look at Earth from the ISS, for example. The green glow around Mars seems to stem from oxygen atoms as well and has been predicted already 40 years ago. But there still needs to be a lot of research done on the behavior of oxygen. Green glow or not, you will always have a first-row seat for Mars with our app Redshift Sky (available for iOS and Android). #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 ...

Of course, the answer is yes, because remember: every body is a beach body. You just need to go to the beach. If you’re still in the middle of slimming down, you might be jealous of our sun. The Sun burns 4,300,000 tons every second. Then again, the sun’s mass is about 1,989,000,000,000,000,000,000,000,000 metric tons.

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. 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. 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. We guarantee you that you won’t have a second date afterward. 😀 But at least you will have time to check out our app Redshift Sky. #fact #facts #didyouknow #science #instafacts #dailyfacts #scientist #knowledge #dailyfact #interestingfacts #knowledgeispower #factzonly #instagood #stars #ceeling #galaxy #photographylovers #photographylife #telescope #outerspace #astronomy #spacetime #astronaut #spacetravel #spacegirl #spacecraft #astrophysics #astrology #universe #spaceapp ... See more View on facebook 1 month ago Chronik-Fotos Human bodies produce a lot of waste. On Earth, we have ways to deal with that. But what do you do with all the pee in space? ESA scientists might have a solution: building moon bases. It sounds a bit disgusting and weird, but recent research shows that urea, the main compound of urine, would help with mixing lunar concrete to make it more malleable before it hardens into its final shape. Not only is this a great recycling concept, but the mixture also seems to be very strong and easy to work with. Before we can move to the Moon or another planet, why not learn more about the Solar System with Redshift Sky? No pee involved, promise. #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 ...

The title of largest goes to Ganymede, one of Jupiter’s many moons. Titan of Saturn, Callisto, and Io (both Jupiter moons) come before our Moon size-wise. But as with many things, we have to see the moons in relation to their planets. The Earth is about 3.67 times larger in diameter than its companion. Ganymede, on the other hand, looks tiny next to Jupiter: the gas giant’s diameter is more than 27 times larger than of its largest moon. Whatever moon in whichever size you’re interested in: you’ll find them all in Redshift Sky. #facts #didyouknow #science #instafacts #dailyfacts #scientist #knowledge #dailyfact #interestingfacts #knowledgeispower #factzonly #galaxy #photographylovers #photographylife #telescope #outerspace #astronomy #spacetime #universe #spacetravel #spacegirl #spacecraft #spacefacts #spaceapp #moon #fullmoon #luna #nightsky #nightphotography #moonlight ...

The survival of the Earth might rely on us preventing future impacts. Like the one that probably happened near the Podkamennaya Tunguska River in Russia on June 30, 1908. We’re still not sure what exactly happened. One hypothesis is that an asteroid hit the area, flattening 80 million trees and causing a rumble that could be detected across Eurasia and as far away as Washington, D.C. Thankfully, this object hit an uninhabited area, so no casualties were reported. Also, if you were wondering why Asteroid Day is on June 30, now you know 😬.

This initiative has quite the glamorous founding story: It was co-founded by Dr. Brian May, who was not only guitarist of the legendary rock band Queen, but also an astrophysicist. (His PhD thesis is called “A Survey of Radial Velocities in the Zodiacal Dust Cloud”, if you’re interested in further reading.) All over the world, there are different events where you can learn more about asteroids. If there are no events where you are, you can always check out our app Redshift Sky – not only on Asteroid Day 😉 #fact #facts #didyouknow #science #instafacts #dailyfacts #knowledge #dailyfact #knowledgeispower #factzonly #photographylovers #photographylife #telescope #outerspace #astronomy #astronomyfacts #spacetime #spacegirl #spacecraft #universe #nasa #space #spaceexploration #hubble #cosmos #galaxy #interstellar #galaxyfaraway #spacetravel #asteroidday ... See more View on facebook 2 months ago Chronik-Fotos When was the last time you appreciated an asteroid? 👀😍 Definitely too long. In preparation of Asteroid Day on June 30, we like to hit you (see what we did there?) with some interesting facts about asteroids. Asteroids are basically mini-planets: Just as planets, they orbit the Sun, but unlike them, their orbit is not disc-shaped. They’re also smaller in size, although the larger ones are called planetoids. If you want to get a closer look at Ceres, Pallas, Juno, Vesta, or Astraea, or other asteroids check out our app Redshift Sky available in Google Play- and App Stores 🤗. #fact #facts #didyouknow #science #instafacts #dailyfacts #knowledge #dailyfact #knowledgeispower #factzonly #photographylovers #photographylife #telescope #outerspace #astronomy #astronomyfacts #spacetime #spacegirl #spacecraft #universe #astrology #nasa #space #spaceexploration #hubble #cosmos #galaxy #flatearth #interstellar ...

You need to be a scientist or engineer and have excellent physical and psychological health. But you also need to embrace being in the public a lot. ESA lists it as one of the requirements. Tweeting from space, interviews, appearances on TV – all part of an astronaut’s job today. If you’re more drawn to exploring rather than explaining space, we suggest using Redshift Sky. #fact #facts #didyouknow #science #instafacts #dailyfacts #scientist #knowledge #dailyfact #interestingfacts #knowledgeispower #factzonly #instagood #photographylovers #telescope #outerspace #astronomy #spacetime #astronaut #spacegirl #spacecraft #universe #astrology #nasa #space #spaceexploration #astronomy #cosmos #galaxy #astronaut ... See more View on facebook 2 months ago Chronik-Fotos Are you missing traveling as much as we do? We can only imagine visiting some tropical beach. But why stop there? Let’s go interstellar! 🚀 Visiting the nearest star first would be an option. So, let’s get out our sky maps (we recommend Redshift Sky) and plan for our hypothetical trip. 🤓 The closest star is the Sun, you might say. And, technically, you’re correct, because the Sun is a star. But when we’re talking interstellar travel, the closest stars would be Proxima Centauri and Alpha Centauri A and B. They’re only 4.22 and 4.3 lightyears from Earth. Basically, around the corner. #fact #facts #didyouknow #science #instafacts #dailyfacts #scientist #knowledge #dailyfact #interestingfacts #knowledgeispower #factzonly #instagood #stars #ceeling #galaxy #photographylovers #photographylife #telescope #outerspace #astronomy #spacetime #astronaut #spacetravel #spacegirl #spacecraft #astrophysics #astrology #universe #astrology ...

We all know of the forces that cause the tides on beaches and coast lines, and some might even feel personal influence of the Moon on their sleep cycle. But the Moon does not only make bodies of water move: the tidal forces are so strong that they even stretch the solid Earth by about 30 cm (about 1ft). If you want to learn more about the Moon, check out Redshift Sky. You can even look at the far side of the Moon 😉. #fact #facts #didyouknow #science #instafacts #dailyfacts #scientist #knowledge #dailyfact #interestingfacts #knowledgeispower #factzonly #instagood #moon #lune #planet #galaxy #photographylovers #photographylife #telescope #outerspace #astronomy #spacetime #universe #spacetravel #spacegirl #spacecraft #spacefacts #explore #cosmos ... See more View on facebook 2 months ago Chronik-Fotos Astronomy is often about measuring distances. But how do you measure the almost immeasurable? You invent new units. Enter the astronomical unit, or AU: it’s roughly the distance from Earth to the Sun, or 150 million kilometers (93 million miles). To be even more precise, an AU has been defined as 149,597,870,700 m. Whatever the distance: you can travel an astronomical unit or a parsec or even lightyears with the device in your pocket.

But today we only have something we don’t know: the origin of the Moon.The most common hypothesis is that a Mars-sized object slammed into the young Earth and catapulted huge amounts of debris into the Earth’s orbit, where it slowly formed into our Moon. But new findings suggest that this might not be true. Scientists found so-called volatile carbon on the Moon. These volatiles only exist if temperatures stay below a certain level. If the Moon was made from impact material, temperatures would have been so high that the volatile carbon would have boiled away. While we wait for scientists to come up with better explanations, you can check out the Moon on Redshift Sky. #fact #facts #didyouknow #science #instafacts #dailyfacts #scientist #knowledge #dailyfact #interestingfacts #knowledgeispower #factzonly #instagood #alien #alienlife #planet #moon #galaxy #photographylovers #photographylife #telescope #outerspace #astronomy #spacetime #universe #spacetravel #spacegirl #spacecraft #spacefacts #spaceapp ...
