Cornell Astronomers Discover Uniquely New Galaxy

Cornell astronomers detailed a newly-discovered galaxy with many unique traits, which make it a subject of further exploration, in a Feb. 17 paper. Published in The Astrophysics Journal Letters, the study found that the newly-uncovered galaxy likely has an efficient star formation rate, meaning that more stars are born per year relative to other galaxies. 

The galaxy, known as SPT0418-SE, was discovered in James Webb Space Telescope images of a well-known galaxy, SPT0418-47. The galaxies are close enough for SPT0418-SE’s  gravitational fields to disturb those of SPT0418-47, a characteristic of the system that appears to contradict earlier research. Such findings are relevant to scientists studying the beginnings of the universe and galaxy evolution.

“It’s like looking at a human,” said author Bo Peng, a doctoral student in astronomy.” Looking at the growth of an infant is much more interesting than a 30-year-old person.”

SPT0418-47 is well-documented due to its unique
