"James Webb Space Telescope Unveils Spectacular Galaxies and Stellar Phenomena"

The James Webb Space Telescope has captured a striking image of the irregular dwarf galaxy I Zwicky 18, located 59 million light-years away in the constellation Ursa Major. The image reveals multiple sudden bursts of star formation within the galaxy, characterized by low heavy element content and surrounded by brown filaments of gas bubbles. The presence of another nearby galaxy may be triggering the star formation. This new insight builds on previous observations by the Hubble Space Telescope and sheds light on the galaxy's life cycle of dust and recent star formation.
