This news is about space. The European Space Agency launches a satellite. Its name is Gaia. It carries a very good camera. It takes pictures of our galaxy, the Milky Way.
The pictures turned into a 3D map. This takes time. There are 1 billion stars in the galaxy. We must wait for the pictures until the end of 2017.
Right now, we have pictures of 2 million stars. The ESA makes a video from this. The video starts in our solar system. It goes through the Milky Way. It ends 150 light years away.
Difficult words: launch (send in the air or in space), Gaia (the ancient Greek word for “Earth”), ESA (the European Space Agency).
The European Space Agency launched its Gaia satellite three years ago. It has a one-billion-pixel camera which takes pictures of our galaxy, the Milky Way.
The camera is making the most detailed 3D map of the galaxy. The information will help answer questions about our galaxy and its future.
We will not get to see the full map with 1 billion stars until the end of 2017, but we have details about two million stars. From this, the ESA made a video. The video goes from our solar system through the Milky Way until 150 light years away.
The European Space Agency’s Gaia satellite is in the process of assembling the most detailed 3D map ever made of the Milky Way Galaxy, including tracking the exact positions and movements of a billion stars.
The satellite is now three years into its mission and the ESA released details of two million stars. From this, the organisation managed to create a virtual journey from our solar system through the Milky Way until we reach 150 light years away.
The information gathered will help answer questions about our galaxy’s structure and how it is evolving. To do this, the spaceship is orbiting around what is called the L2 Lagrangian points while utilising a billion-pixel camera.
We will not get to see the full map with 1 billion stars until the end of 2017. Then we will really know what is beyond the dark side of the moon.
Difficult words: assemble (put together), track (follow the movement of something), gather (collect), utilise (make use of).
