Off to Distant Worlds

Astronomy is the fascinating science of stars, planets, and outer space. It helps us understand how our universe works, why stars shine, and what secrets are hidden within our solar system and distant galaxies.

With a telescope, you can observe stars, planets, and even distant galaxies more closely and discover many details that are invisible to the naked eye.

What Types of Telescopes Are There?

[Image of Moon] [Image of Telescope] [Image of Telescope labeled]

Refractor Telescope

In a refractor telescope, light is focused using a large lens.

The lens collects the light and creates an image that you can see through the eyepiece. The eyepiece magnifies the image so you can see details. Refractor telescopes are easy to use and ideal for observing the Moon, stars, or planets like Venus. They are perfect for beginners because they are simple to handle and produce clear images.

Finder Scope

Why do you need this additional small telescope?

Many telescopes come with an additional small telescope. Why do you need a finder scope? It helps you locate planets more easily, as this is almost impossible with the naked eye. Once you’ve found an object, align the crosshairs to the center. In the finder scope, everything appears upside down and mirrored—but this does not interfere with observation. It offers a wider field of view, making it easier to locate celestial objects before switching to the higher magnification of the main telescope.

Tips for Observing

Tip 1
Instructions Step 1

Try It in Daylight First

Use your telescope for the first few times while it’s still bright outside. But be careful: never look at the Sun through a telescope! Once you’re familiar with how it works, nothing will stand in the way of observing the stars.

Tip 2
Instructions Step 2

Never Look Through a Window

Never observe through a window or a door. Through glass, it’s almost impossible to focus the image properly. Open the window if you want to see something.

Tip 3
Instructions Step 3

Get Used to the Magnification

Work your way up slowly to higher magnifications. It’s easiest to start with the lowest magnification.

Tip 4
Instructions Step 4

Dark & Cloud-Free

Pay attention to the weather. Depending on the conditions, observing can become difficult. Your observing location should be as dark as possible.

Image of the Sun and Earth

The Sun is a huge, blazing ball of gas.

It’s so big that more than a million Earths could fit inside it.

Frog Ferg
Structure of the Sun

Its surface is 5,500 degrees hot.

And inside, it’s as hot as 15 million degrees!

Frog with sunglasses
Sun shining its rays on Earth

Sunlight takes only 8 minutes to reach Earth.

Without the Sun, there would be no life. It provides warmth, light, and helps plants grow.

Solar Eclipse

Do you know what a solar eclipse is? It happens when the Moon moves in front of the Sun, so it suddenly gets dark during the day.

You’ll be able to experience this impressive event twice over the next two years:

on 12 August 2026 and
on 02 August 2027.

The Layers of the Earth

The Earth has several layers—like an onion or an egg. On the outside is the Earth’s crust, below that the mantle, then the outer and inner core. The core lies about 6,371 km deep and is very solid because the pressure there is the greatest.

Diagram of the layers of the Earth
This is the Earth’s crust

On the very outside is the Earth’s crust. It’s like the shell. This is where we live—where the seas, mountains, cities, and forests are.

This is the Earth’s mantle

Below that is the Earth’s mantle. It is very hot. Sometimes the rock there is solid, sometimes it is liquid—like lava from a volcano.

This is the outer core

The outer core lies beneath the mantle, is liquid, and very hot.

This is the inner core

The inner core lies in the center of the Earth. It is even hotter, but solid, because the pressure there is enormous. Together, the outer and inner core keep the Earth warm and strong.

Fun Facts About the Milky Way

Fact 1
Fun fact 1

Where does the name “Milky Way” come from?

The ancient Greeks thought it was spilled milk across the sky.

Fact 2
Fun fact 2

The Milky Way is a barred spiral galaxy

It has a thick bar of stars in the center, with spiral arms around it that look like the twists of a snail shell.

Fact 3
Fun fact 3

We can only see a small part of it

From Earth, we can see only about 6,000 stars. In reality, the Milky Way contains between 100 and 300 billion stars.

Fact 4
Fun fact 4

The Milky Way isn’t actually that big

Even though it seems huge, the Milky Way is just one of many galaxies in the universe—some, like the Andromeda Galaxy, are even much larger.

The Earth's Atmosphere

EXOSPHERE


>700 TO 190,000 KM

The exosphere is the outermost layer of air around our Earth. Satellites orbit the Earth in this layer and send us things like weather images or GPS signals. 🛰️

THERMOSPHERE


80 TO 700 KM

Thermosphere In the thermosphere, the air is very thin, but the temperature can get extremely hot—over 1,000 degrees! This is where the Northern and Southern Lights glow, and the International Space Station (ISS) orbits the Earth here. 🌡️

MESOSPHERE


50 TO 80 KM

Mesosphere
Frog in space

Look up at the sky on a clear night—maybe you’ll spot a shooting star!

Here the air is already very thin and it gets very cold. In this layer, many meteoroids burn up before they reach Earth. When that happens, we see them as shooting stars in the sky. 🌠

STRATOSPHERE


12 TO 50 KM

Stratosphere It starts above the troposphere and reaches up to about 50 km in altitude. The ozone layer is located here and absorbs a large portion of harmful UV radiation. ☀️

TROPOSPHERE


0 TO 12 KM

Troposphere The lowest layer, where we live and where almost all weather phenomena occur. 🌧️

BRESSER JUNIOR Astro Planetarium
The BRESSER JUNIOR Astro Planetarium quickly transforms your ceiling into a starry sky. And then it’s time for you to go exploring: This home planetarium projects over 8,000 stars and 61 named constellations using 2 projection discs and a bright LED, bringing the universe into your home. Ever curious about the constellations visible on your birthday? Why not have a look? Just set the date and a time between 8 PM and 2 AM, because during this time there will always be stars in the sky. Then just switch on the children's planetarium and the night sky of your birthday lights up above you. For the best experience, maintain a 2-meter distance from the ceiling. This allows the projection to cover a substantial area of approximately 1.6 x 2.1 metres. A focusing wheel ensures the celestial display is crystal clear. This is not just for special occasions like Christmas or birthdays; it's a year-round gateway to the stars. Use the star projector to enjoy the night sky indoors If you've ever used a telescope, the most crucial tool for stargazers, you know that clear skies are essential. Cloudy skies can obscure your view of the heavenly bodies. With this home planetarium, however, weather is no impediment. Rain or snow, your exploration of astronomy continues indoors. Thanks to its built-in motor, the projected sky rotates automatically. A counter-clockwise rotation mimics the natural movement of the northern hemisphere, while a clockwise rotation aligns with the southern hemisphere's pattern. Choose from 6 speed settings to tailor your experience. The shooting star mode adds a dash of magic, bringing meteor trails across your ceiling. Drift off to sleep under the stars There's something incredibly soothing about falling asleep under a starlit sky. The sleep mode turns off the home planetarium automatically after 30 or 60 minutes. For longer enjoyment, let it run normally, and it will switch off after 2 hours to conserve energy. You'll likely be deep in dreams of cosmic adventures by then. Turn your home into a place for celestial explorations with the BRESSER JUNIOR Astro Planetarium. FEATURESStar projector suitable for children aged 14 and up Shooting star function Automatic shut-off (after 30, 60, or 120 minutes) Projection area of 1.6 x 2.1 metres (at a 2-metre distance) 1 bright, white LED Motion-enabled projection through dual motors offering 6 speeds Focusing wheel for clear images Night sky simulation on walls or ceilings, adjustable for specific dates and times More than 8,000 celestial bodies and 61 constellations on 2 projection discs Maximum projection distance: 3 metres SCOPE OF DELIVERYAstro planetarium 2x projection discs 3x AA batteries Instruction manual
