Firework Displays are not unique to Earth anymore. The Hubble Telescope has detected a spectacular fireworks display in a galaxy nearby. The small galaxy looks like a lit up Fourth of July celebration.
For Kiso 5639 galaxy, the event is a star being born. This rare occurrence has filled the pancake shaped galaxy with sparkles, making it look like a skyrocket with a star-studded tail and a blazing head.
Kiso is a rare, close-up example of what used to be a common event during the early stages of the Universe: the birth of a star. Researcher Debra Elmegreen has pointed out that the Milky Way, Earth’s galaxy, must have gone through a similar stage, as it grew up.
With modern telescopes like Hubble, researchers are now able to look further into the Universe, which means they can see earlier stages of galaxy forming as their current situation is still light years away from us.
The Kiso galaxy is special because it seems out of sync with other galaxies, which have already formed stars. 10 % of all galaxies have pancake, elongated shapes and are called “tadpole galaxies.”
The galaxy is located around the corner, at an 82 million light-year distance. It’s development lasted for billions of years because it has been floating through an area of the Universe poor in gas.
The atypical galaxy measures 2,700 light years across. Its’ stars are less than 1 million years old and have huge masses.
When these star-forming, tadpole galaxies were first discovered in the 90’s, scientists believed that the unusual firework-like activity was because of them colliding with other galaxies. Now, based on computer simulations, a new theory emerges: that these galaxies encountered large gas deposits, as they drift through space.
A large amount of gas acts like a filament, firing up the galaxy and giving birth to new stars. Astronomers hope that by studying such objects, they will learn more about galaxy evolution, and may even lead to uncovering the processes which form starbursts and globular clusters.
New filters were installed on the Hubble telescope, which now allow it to see clearer, more detailed images of firework displays in galaxies. The young stars in Kiso Galaxy are up to six times more massive compared to stellar bodies seen in other galaxies.
