It's a year since the James Webb telescope launched, and we've marvelled at its pictures ever since.
The first thing you have to remember about James Webb is that it is an infrared telescope. It sees the sky at wavelengths of light that are beyond what our eyes are able to discern.
Astronomers use its different cameras to explore regions of the cosmos, such as these great towers of gas and dust. The Pillars were a favourite target of Hubble. It would take you several years travelling at the speed of light to traverse this entire scene.They call this scene the Cosmic Cliffs. It's the edge of a gigantic, gaseous cavity within another dusty, star-forming nebula, known as Carina.
The cavity has been sculpted by the intense ultraviolet radiation and winds from hot, young stars just out of shot. From one side of this image to the other is a distance of roughly 15 light years. One light year is equal to about 9.46 trillion km .This large galaxy to the right was discovered by the great Swiss astronomer Fritz Zwicky in the 1940s. Its intricate cartwheel structure is the result of a head-on collision with another galaxy. The diameter is about 145,000 light years.James Webb doesn't look into only the deep Universe. It probes objects in our own solar system, too.
