IUCAA Astronomers Discover Giant Bubbles Around Tiny Galaxy
Imagine a tiny galaxy far, far away, like a little city that's making lots of new stars very fast.
These stars don't live long and explode, creating huge bubbles around the galaxy, kind of like giant soap bubbles.
Scientists in India have found these massive bubbles around one of these tiny galaxies.
These bubbles are caused by powerful winds from the explosions.
They are much bigger than the galaxy itself, and even bigger than any seen before, which is a surprise to scientists.
These bubbles help scientists understand how galaxies grow and change over time, especially in the early universe.
Astronomers discovered giant bubbles surrounding a small galaxy named J1044+0353.
The galaxy is 170 million light-years away and has a diameter of 7,100 light-years.
The bubbles are 23,000 light-years in diameter, some intact, some seemingly popped.
Supernovae from massive stars are thought to create these galactic winds and bubbles.
These bubbles are larger than any previously observed around similar galaxies.
