“Where did the Milky Way come from?” , — Scientists ask questions, in the words of historian Nestor. If we study similar objects from their origins in the early universe, it is possible to reconstruct the evolutionary paths of our galaxy. Of the trillions of galaxies in the universe, there are billions of galaxies not unlike the Milky Way. Such a galaxy was discovered thanks to gravitational lensing. This is our galaxy’s newborn twin; It is only 600 million years old.

The twin galaxy of the Milky Way received the poetic name Firefly Sparkle. amplifying light from a distant galaxy. They were able to study its structure and detect several star-forming regions within it.

For the most part, the success in observing this object was achieved due to the high sensitivity of the infrared sensors of the space observatory named after it. James Webb. It was his sensors that helped create the image of a distant, young galaxy after the distortions inevitable during gravitational lensing.

The Firefly Sparkle galaxy is observed 600 million years after the Big Bang. It has 10 different active star formation regions. Regions each have a mass of 10 or more⁵ up to 10⁶ solar masses These observations provide science with the first spectrophotometric view of a typical galaxy in the early stages of its development in the universe. The Firefly Galaxy even has two companion dwarf galaxies, whose role in the Milky Way is played by the Large and Small Magellanic Cloud galaxies.
