SMM J2135−0102

SMM J2135−0102 is not just one star, but a super-duper bright galaxy far, far away! It's like a giant factory making new stars. This galaxy is so special because it's one of the brightest things we've ever seen in the universe. It's like finding the biggest, brightest toy in the whole toy store, but it's a galaxy instead!

How can we see something so far away? It's like magic, but it's science! There's another galaxy in front of SMM J2135−0102 that acts like a giant magnifying glass. This other galaxy bends the light from SMM J2135−0102, making it look even brighter and bigger to us here on Earth. It's like looking through a special lens that makes things appear much closer and clearer.

This galaxy is incredibly busy making stars! It's like a busy playground where lots of new stars are being born all the time. Scientists think it's making stars at a super-fast rate, much faster than our own Milky Way galaxy. This makes it shine with a brilliant light that travels across the universe to reach our telescopes.

When we look at SMM J2135−0102, we're not just seeing it as it is now. Because it's so far away, the light has taken a very, very long time to reach us. So, we're actually seeing SMM J2135−0102 as it was when the Earth was very young! It's like getting a postcard from the distant past, showing us what the universe looked like a long time ago.
