A galaxy held together by gravity and is a huge collection of gas, dust, billions of stars and their solar system. Galaxies come in a variety of sizes, from small dwarf galaxies with only a few billion stars to giant elliptical galaxies with trillions of stars. Although most galaxies are elliptical in shape, a few have unusual shapes like toothpicks or even rings. Although many galaxies lie thousands or even millions of light-years away from Earth, NASA, ESA and other space agencies have closed this gap with the help of advanced technology.
James Webb Space telescope how wonderful we with its capacity with each passing day. NASA’s $10 billion space telescope has captured breathtaking images of distant galaxies, star clusters, black holes, etc. Now it’s added another feather to its hat by imaging a spiral galaxy called LEDA 2046648, located nearly 1 billion light-years from Earth in the constellation Hercules. LEDA 2046648 can be seen behind spatial crowded by many other stars and galaxies.
What is a Spiral Galaxy?
According to NASA, Spiral galaxies are actively forming stars that make up a large number of galaxies in our neighboring universe. They can be divided into two groups: normal spirals and barred spirals. In barred spirals, a bar of stars runs through the central bulge of the galaxy.
JWST’s amazing technology captured the image
The image was captured by the James Webb Space Telescope’s Near Infrared Camera (NIRCam), which is the main camera on the telescope. It has three dedicated filters and takes pictures in two different infrared bands. Incredibly, it is capable of capturing some of the farthest near-infrared images ever obtained, detecting light from the first stars and galaxies. NIRCam also has spectral and coronal capabilities and is the primary tool for telescope alignment.
