This image is historic. It’s the first time humans saw the entire Earth with their own eyes. The Apollo 8 astronauts took this picture on as they ventured into deep space on December 1968. Till today only 24 humans had the chance to see the Earth from this distance.

There is no better place than space to realise the inherent unity and oneness of everything on the planet and the irreplaceable value it has for all of us.

Frank Borman, one of the three astronauts on bord of the Apollo 8 spacecraft said:

The view of the Earth from the Moon fascinated me – a small disk, 240,000 miles away… Raging nationalistic interests, famines, wars, pestilence don’t show from that distance.

The Cosmic Watch is not just a clock, it’s an astronomical instrument which visualizes the cycles of Earth and the solar system, helping to understand how we measure and experience time since thousands of years.

#frb_text_1439143517.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1439143517.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

The Earth is the central focal point of the Cosmic Watch. It can be used to demonstrate the apparent movement of the sky and celestial objects around us. It also shows beautifully the concept of the celestial sphere and celestial coordinates used in navigation and to locate objects in the sky.

The Cosmic Watch is a virtual planetarium on your mobile device. It calculates the positions of the sun, moon, planets, stars and constellations, in relation to the earth and time. It gives us the possibility of observation from different points of view as well as to add several layers of information.

#frb_text_1513947224.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1513947224.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

The Cosmic Watch starts in the clock mode.

Tap on the Cosmic Watch logo on the top left to show or hide the control buttons (GUI).

Swipe the screen in a direction to rotate the globe or your view.

Pinch the screen to zoom in or zoom out.

The Clock mode is the default setting to use the Cosmic Watch as a desktop clock. Connect your tablet to the electricity and find a nice tablet stand. To disable the automatic sleep mode of the tablet go to the device settings and choose “don’t sleep while recharging”. (This can also be called Kiosk mode). Find out more here.

The Astrology mode shows the planets with their ancient symbols in the zodiac signs. Set your birthday on the time control to show your natal chart. Use the horizon to find out which sign is your ascendant. You can see the moon knots, the points where the eclipses take place. Use the planet connections to see if a planet is at opposition or conjuction. The interpretation is up to you!

This view is centred on Earth. We call this a geocentric point of view. The sun, the planets and the sky rotating around Earth is an optical effect which happens because the earth is rotating every day on its own axis. The moon is the only celestial object actually rotating around the Earth.

We all know that the Earth and all the planets are rotating around the Sun. Seen from Earth it looks like the Sun is rotating around us, passing through all the zodiac constellations in a year.

#frb_text_1153585761.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1153585761.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

The Solar System View shows the clockwork of the Cosmic Watch. This view has the option to see it from a geocentric or heliocentric perspective. The former has the Earth fixed in the centre and the latter the Sun – showing the real motion of the planets around their star. The geocentric view is handy to understand how we experience the solar system from Earth.

Fast-Forward time to see the planets moving and understand their apparent motion in the sky with the geocentric option. This is a clear representation of the retrograde motion of planets!

All orbits are represented in a realistic scale.

THE CLOCK

#frb_text_1341731895.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1341731895.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

The clock face of the Cosmic Watch is set on the Ecliptic. The sun, the moon and the planets are always around this imaginary line, as this is somehow the plane of the solar system.

#frb_text_1891041523.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1891041523.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

The time dial points from the selected location to the 24 hours clock face. This allows to visualize the day as one circle and see how much time has passed and how much of the day is left.

#frb_text_2018257524.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_2018257524.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

The ecliptic clock face show the approximate time around the world. (-> see time on earth)

#frb_image_484375245.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_image_484375245.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms; #frb_image_484375245 .frb_image_hover background:#000000;

An interesting property of the clock-face is that it shows at which approximate time the celestial bodies will be at the highest point in the sky. For example, the Sun pass the meridian approximately at 12 o’clock and a full moon will pass the meridian at approximately 12 o clock in the night.

#frb_image_1451333764.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_image_1451333764.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms; #frb_image_1451333764 .frb_image_hover background:#000000;

To customize your clock tap on SETTINGS (the gearwheel left-down the screen) and tap on CLOCK. You can display the YEAR as a circular calendar where the sun marks the date. You can see visually where in the year you are right now and when the next SEASON will start.

#frb_text_1748453923.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1748453923.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

The DIGITAL button is useful if you want to have the cosmic watch as your daily clock, like I do 🙂

#frb_text_1728195401.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1728195401.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

Like every clock the cosmic watch has also a SECOND dial showing how long a minute is.

#frb_separator_1766791394.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_separator_1766791394.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

THE TIME CONTROL

#frb_text_605725019.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_605725019.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

The Time control is the main feature of the Cosmic Watch and holds the key of understanding the apparent motion of the sky.

#frb_text_768012772.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_768012772.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

To fast-forward the time is a mind blowing experience. It’s like watching a time-lapse video. Perhaps we don’t know how the future will be, but we know where the planets will be. (The cosmic Watch should be accurate for the next thousand years 🙂

#frb_image_1867344120.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_image_1867344120.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms; #frb_image_1867344120 .frb_image_hover background:#000000;

Tapping the fast-forward button consecutive times allows the user to speed up the Time. By one day per second the Cosmic Watch releases the Anchor so you don’t get crazy turning around! Note that on an earth scale this rate looks fast but on a solar system scale it’s still very slow.

#frb_image_1179336310.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_image_1179336310.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms; #frb_image_1179336310 .frb_image_hover background:#000000;

The ANCHOR is a very important function. With this button we can anchor the camera and rotate with the Earth. We call this a topocentric point of view. It’s like a geostationary satellite, like the ones we use for weather monitoring. (check links to find out more) With the anchor on, it looks like the sky is rotating around the Earth, like we experience from the Earth’s surface.

#frb_text_1484448501.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1484448501.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

By releasing the Anchor the user can float freely in space around the Earth. The observer is still geocentric, (the Earth is at the center), but able to see that it’s actually the Earth which rotates around its own axis. The stars are the only objects that are fixed. Like this one can observe the moon moving around the Earth and the Sun’s apparent movement through the zodiac constellations.

#frb_image_1089162344.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_image_1089162344.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms; #frb_image_1089162344 .frb_image_hover background:#000000;

With the pause button you can stop fastforwarding or rewind time and get to a normal time flow at that specific moment. You can’t stop time on the cosmic watch, we did this on purpose, because this seems to be a quality of time, it never stops, it just keeps flowing!. When you press pause you will see at the bottom of the time control the time difference to now. With this feauture you can find out how many days old you are or how many days are left to your next birthday!

To go back to the present just press the NOW-button! (the circle with the triangle)

#frb_text_1472115241.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_text_1472115241.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

With the little arrows (triangles) over and under the time and date display you can choose any moment you like. You can watch how the planets where at the moment of your birth, or find out when the next full moon will be.

While fast forwarding time, the planets will leave a trace of their apparent movement as observed from Earth. Like this it is very easy to understand what a Retrograde motion looks like. Combined with the solar system view one can have a clear observation and visual understanding of why this phenomenon happens.

The horizon is a very important guide because it defines your actual vision of the sky. You can only see half of the sky because the other half is under the horizon. In combination with the time control you can find out when a celestial body is going to rise (pass the horizon to the East) and set (pass the horizon to the West)

You can switch on the horizontal coordiantes button to locate an object in the sky. This coordinate system is widly used in astronomy and celestial navigation. It also shows the zenith and the meridian of your location. (more info)

Use the compass to align your device to north. Unfortunately the compass is not always functioning very well depending on the specifications your device. But luckily you can find out where north is with the cosmic watch itself if the time and the location are correct. During the day you can align the cosmic watch with the sun and during the night you will need the moon, a planet clearly recognizable or any of the star constellations. This is how explorers on both land and sea use to navigate themselves.

The connections are the essence of the Cosmic Watch and are the true dials of this clock.

Everything is connected in the universe

When this lines overlap, the celestial bodies are in conjunction. This means they are aligned with the Earth. A new moon is a conjunction of the moon with the sun.

#frb_h_170021678.frb_onScreen.frb_animated -webkit-animation-duration: 1000ms; animation-duration: 1000ms;#frb_h_170021678.frb_onScreen.frb_hinge -webkit-animation-duration: 2000ms; animation-duration: 2000ms;

There is a little marker opposite to each planet position. This marker helps to find planetary oppositions. In this case the celestial bodies are also aligned, with the Earth in between them. A full moon is a opposition of the moon with the sun.

This is the educational part of the cosmic watch. This option is named like this, in honor of the armillary sphere, which is still used to demonstrate the apparent movement of the sky and means “the instrument with the rings”. These are the main guidelines you need to know for observation of the sky.

The Ecliptic is the plane of Earth’s orbit around the Sun. Seen from the Earth it is the optical path of the Sun in one year. The 12 constellations on this plane are the zodiac. The Sun, the Moon and the planets are allways found close to the ecliptic. (more info)

The celestial equator is the projection of the Earth’s equator in the sky. The stars appear to move parallel to this line. To find it in the sky, find the Orion constellation. It passes over the equator, and as three stars aligned. This line is in a right angle (90°) with the celestial north and south poles, which are the center points of the apparent rotation of the sky because the axis of the Earth points towards them. (Precession) This line crosses the horizon exactly due East and West.

This is the preferred coordinate system to pinpoint objects on the celestial sphere because they are independent of the observer’s location and the time of the observation. They are used to set the telescope. (more info)

The Celestial Sphere is a simplified model of the sky, where all the stars are considered to be the same distance away from us, like on the surface of a sphere. It’s used for orientation and to locate objects in the sky.

Halo (optical phenomenon)

Halo is the name for a family of optical phenomena produced by light interacting with ice crystals suspended in the atmosphere. Halos can have many forms, ranging from colored or white rings to arcs and spots in the sky. Many of these are near the Sun or Moon, but others occur elsewhere or even in the opposite part of the sky. Among the best known halo types are the circular halo (properly called the 22° halo), light pillars and sun dogs, but there are many more; some of them fairly common, others (extremely) rare.

The ice crystals responsible for halos are typically suspended in cirrus or cirrostratus clouds high (5–10 km, or 3–6 miles) in the upper troposphere, but in cold weather they can also float near the ground, in which case they are referred to as diamond dust. The particular shape and orientation of the crystals are responsible for the type of halo observed. Light is reflected and refracted by the ice crystals and may split up into colors because of dispersion. The crystals behave like prisms and mirrors, refracting and reflecting light between their faces, sending shafts of light in particular directions.
