Irregular galaxy NGC 7673
Irregular galaxy NGC 7673, optical Hubble Space Telescope image. Intense star birth regions (blue) make this a starburst galaxy. Two other galaxies are seen (centre right and upper right) in the background. Two theories may explain the large amount of star birth activity. NGC 7673 may have collided with another galaxy, prompting implosions of gas clouds to form stars. The other theory says that this could be an example of the vigorous star formation that occurred in the early history of the universe. NGC 7673 lies around 150 million light years away in the constellation Pegasus. Photographed in 1997

EDITORS COMMENTS
This print showcases the irregular galaxy NGC 7673, a mesmerizing celestial wonder captured by the optical Hubble Space Telescope. The vibrant blue regions within this star-studded galaxy indicate intense star birth activity, earning it the classification of a starburst galaxy. In the background, two other galaxies can be observed, adding to the cosmic spectacle. Scientists have put forth two theories to explain the remarkable abundance of star formation in NGC 7673. One suggests that this galactic phenomenon may have been triggered by a collision with another galaxy, causing gas clouds to implode and give rise to new stars. Alternatively, it is proposed that this extraordinary display could be an example of vigorous star formation occurring during the early stages of our universe's history. Located approximately 150 million light years away in the constellation Pegasus, NGC 7673 remains an enigmatic beauty awaiting further exploration and study. This photograph was taken in 1997 using Hubble's Wide Field Planetary Camera 2 (WFPC2), capturing intricate details and offering valuable insights into galactic evolution and cosmology. Immerse yourself in this unique glimpse into our vast universe as you marvel at NGC 7673's peculiar characteristics and its role in unraveling some of nature's most profound mysteries.
