In December 2021, a new telescope was launched into space. It was the James Webb Space Telescope. It took a long time to build. It cost a lot of money. The Webb telescope is one of a kind. It is the most powerful telescope ever built.

The Webb telescope uses mirrors to make images. The mirrors are covered in gold. They collect light from faraway stars.

The telescope can see infrared light. This light is invisible to our eyes. But we can feel it as heat. Infrared vision helps the telescope see through space dust.

Stars and planets form from gas and dust. Seeing into the dust can help us see how they form.
