NASA's Hubble captures dozens of blooming pink nebulae in spiral galaxy NGC 2835

This NASA/ESA Hubble Space Telescope image features the nearby spiral galaxy NGC 2835.

The universe never stops surprising us, and now Hubble has revealed a new face of a familiar spiral galaxy. The telescope’s latest image of NGC 2835, located 35 million light years away in Hydra, highlights fresh details.

What makes this image different from earlier ones?
Unlike past releases from Hubble and the James Webb telescope, this view includes new Hubble data. It captures a specific red wavelength of light called H-alpha. This addition shows bright regions across the galaxy’s spiral arms. The striking pink nebulae resemble flowers blooming against the starry background.

Why are astronomers interested in H-alpha light?
H-alpha emission signals the presence of different nebulae. Young massive stars form H II regions that emit strongly in H-alpha. Old stars also contribute, producing supernova remnants or planetary nebulae. Each phase adds new detail to the galactic landscape as it evolves.

What are researchers hoping to learn from this survey?
By using Hubble’s advanced instruments, scientists plan to map 19 nearby galaxies. They aim to identify more than 50,000 nebulae in total. The findings will explain how starlight and stellar winds shape star-forming regions. This could deepen our knowledge of how stars transform their cosmic neighbourhoods.
