New stars are being formed in sites where “hydrogen atoms are stripped of their electrons by intense radiation from massive, young stars”
When you look at the above image, please note that:
“Small stars are scattered throughout the NGC 346 region, while massive stars populate its center. These massive stars and most of the small ones formed at the same time out of one dense cloud, while other less massive stars were created later through a process called “triggered star formation”. Intense radiation from the massive stars ate away at the surrounding dusty cloud, triggering gas to expand and create shock waves that compressed nearby cold dust and gas into new stars. The red-orange filaments surrounding the centre of the image show where this process has occurred.”
