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. Redshift Sky helps you travel our Solar System completely hassle-free.

Usually, we give you facts on what we know about space. 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.

Look into the sky – what do you see? If it’s bright and neither the Moon nor the Sun, don’t call NASA just yet for a UFO sighting 👽.
It's probably Venus. Named after the Roman goddess of love, it’s beautiful to look at – from far, far away. From up close, Venus is basically hell: with surface temperatures of 470 C, an atmosphere made of carbondioxide, and sulphuric acid rains that evaporate immediately before even hittingthe ground. Definitely no place for a human. If it’s too cloudy to enjoy Venus in living colors in the night sky, head over to our app Redshift Sky to see it in all its hellish beauty.

Even without Martians: exploring the Red Planet is still one of the most exciting endeavors of humankind. Before anybody sets foot on Mars, NASA’s Rovers will do the groundwork. After Spirit, Opportunity and Curiosity the next rover to explore Mars will be called Perseverance and is set to launch in July 2020.

Alex Mather, a Virginia seventh grader, came up with the name. In his submission to NASA’s naming contest he writes: “If you think about it, all of these names of past Mars rovers are qualities we possess as humans. (…) If Rovers are to be the qualities of us as a race, we missed the most important thing: perseverance. We as humans evolved as creatures who could learn to adapt to any situation, no matter how harsh.”

We were at the edge of our seats but alas, ‘twas not to be: this week the spaceship Crew Dragon was scheduled to launch for a trip to the ISS. It would have been the first time in nine years that a NASA mission would head to the ISS from national ground.
Only 15 minutes before lift-off, the launch was canceled due to the weather conditions. Even with our advanced technology, the rule still applies: bad weather is the natural enemy of space exploration.
We feel sorry for the thousands of people who traveled to NASA’s Kennedy Space Center in Florida for the launch. Our next chance is on Saturday, 1922 GMT. We keep our fingers crossed for better weather. Will you be watching attempt no. 2? 👀

Many people are still salty that Pluto has been demoted to dwarf planet (Let it go, please! It’s been 15 years!). Other objects might be happy if they earned the title of dwarf planet – like Hygiea. 🥇
Hygiea always checked three of the four boxes for dwarf planet, namely it orbits around the Sun, it’s not a moon, and it has not cleared the neighborhood around its orbit like a full-sized planet. Just now we were able to check for the final criterion: an (almost) spherical shape. Thanks to the VLT (Very Large Telescope), astronomers could see that this is the case. And another title might await Hygiea: It could be the smallest dwarf planet in our Solar System, even smaller than Ceres.

So, go Hygiea, and congratulations! 🏆 It’s one small reclassification for man, but a great promotion for a former asteroid.

As we live on Earth, we consider a planet with a magnetic field as something normal. But even in our Solar System it’s not that common – of the rocky planets in the inner Solar System, only Earth and Mercury have one. And with Mercury, we are not sure why.
Scientists considered Mercury too small to have a magnetic field, which is one hundred times weaker than that of Earth. One hypothesis is that, like Earth’s magnetism, Mercury’s core must at least partially be molten.
But more data will hopefully be on the way: 🚀 ESA’s and JAXA’s BepiColombo mission is sending two orbiters to Mercury to find out more about its core. Estimated arrival is December 2025. While we wait for results, you can watch Mercury on our app Redshift Sky.

Rock solid, gaseous, or uninhabitable wasteland – there are many words to describe planets. But we never thought that “cotton candy-like” would be one of them. But those planets exist, and their nickname will melt your heart: NASA calls this newly discovered class of planets super-puffs 😍.
The solar system Kepler 51 has several super-puff planets. Unlike planets in our solar system which are mostly terrestrial, liquid or gaseous, Kepler-51 b and Kepler-51 d are very low in density. These planets are nearly as big as Jupiter, with only 1/100th of its mass – like a spoonful of sugar that is spun into a huge cloud of cotton candy. There’s still so much to discover in space, and with Redshift Sky you can go on an expedition on your phone.

When it comes to naming things in space, astronomers love using terms from Greek mythology. And we can’t be mad at that; after all, mythology is a treasure-trove of imaginative creatures.

Which is why it makes sense (kind of), to call Centaurs after the mythological mix of humans and horses. In astronomy, Centaurs are a hybrid between asteroid and a comet. The icy planetesimals can be found between Jupiter and Neptune. Since they cross the orbits of giant planets on their path around the sun, their own orbits are rather wobbly.
What objects classify as Centaurs is still up for debate; there are different criteria for Centaurs. But let this not deter you to discover more small Solar System bodies with Redshift Sky.

In ancient times, people feared the wrath of the Heavens or the sky falling on their heads.👷‍♂️ And truth be told, space is a dangerous place for humans – even when you’re not actually in space, as one unfortunate soul had to experience on Aug. 22, 1888.

That is the date of the first recorded death caused by a Meteorite. A group of researchers in Turkey found the incident in old records from the Ottoman Empire. According to the documents, the meteorite not only killed one person in Sulaymaniyah, Iraq, but also severely injured another.
Probably another good reason to stay home and stay safe. For exploring the sky safely, we recommend our app 😇.

PLUTO HAS A HEART OF ICE ❄️ 💛


We’ve all seen the wonderful high-resolution pictures of Pluto from the New Horizons flyby, and we all fell in love with the bright heart-shaped region on Pluto’s surface. While the view might be heart-warming, temperature-wise Pluto’s heart is rather cold because it’s made of different ices.
The Tombaugh Regio, as the heart is officially called, contains nitrogen, carbon monoxide, and methane ices. Wander the icy plains of Pluto’s surface yourself with our app Redshift Sky.

There are many objects flying around in the Solar System, some large, some small. Vesta earns the title of largest asteroid in our solar system: It has a diameter of 530 km at its widest, which is roughly to the distance from Berlin to Vienna. And before you ask: Ceres used to have this title, but since then has been promoted to dwarf planet status. Travel tens of thousands of kilometers with a tip of your finger - with the new app Redshift Sky for Android and iOS no distance is too far for you!

How do you feel today? Well rested? Or did you wake up feeling like a zombie, in desperate need of brains?

In space, you might not wake up feeling like a zombie, but you sleep like one. As gravity even in Earth’s orbit is considerably lower than on Earth, your arms tend to float up, leaving astronauts in the zombie sleeping position. To avoid that you would have to strap your arms to your sleeping bag, which is probably too uncomfortable for a good night’s sleep.
How about space discovery from your own bed? Our app Redshift Sky works great 😉

Have you ever seen a solar eclipse? For most people, it is a once in a lifetime event.
Except that this is not the whole truth:
Every year, about three to five solar eclipses occur.
However, most of them are either partial eclipses, i.e. the Moon only covers parts of the Sun, or annular eclipses, i.e. the moon is directly in front of the Sun, but the Moon seems too small so that a ring of the Sun is still visible. In many of these cases the Sun is too bright to recognize more than a slight dimming 👀.

The special solar eclipses are, of course, the total ones. These are indeed very rare. Statistically speaking, there is a total solar eclipse about every 18 months somewhere on Earth. But not every place on Earth has the same chance of experiencing a total eclipse: mathematicians calculated that some places might see one only every 400 years 🙄!
To get a good view of our Sun without damaging your eyes check out our app Redshift Sky Pro.

A grain of sand can hide 10,000 galaxies!

We all know that space is, well, spacious. But let’s look at an example to demonstrate the vastness of our universe:
if you hold a grain of sand in the night sky, the surface that this grain covers will hide about 10,000 galaxies 🌌.
Galaxies that are as big or even bigger than our own, the Milky Way.

With the new app Redshift Sky for Android and iOS, nothing remains hidden from you. Start your expedition into space now and discover the universe anew! 🔭
