NASA’s Hubble Telescope has discovered numerous “ghost” stars wandering in giant galaxies for billions of years.
These stars are not gravitationally bound to any galaxy.depending on the page Daily Scitech.
A recent infrared study by the Hubble Space Telescope shows that these stars have been wandering for billions of years.
When did they get lost in intergalactic space? The true origin of these orphan stars remains a mystery.

Thanks to the Hubble telescope, astronomers now know wandering star families. There isn’t even a possible galaxy that stars can call “home.”
The diffuse, dim light from lone stars creates a ghostly background light within the galaxy cluster.
Clues about lonely stars were first discovered in 1951. In fact, Hubble can now easily detect the light from these stars. It’s only 1/10. 000 lights of the night sky seen from ground-based telescopes.
Understanding the origin of light within galaxy clusters could give astronomers new insights into the history of galaxy clusters.
The nagging question for astronomers: How did the stars get scattered throughout the galaxy cluster in the first place?
Some scientists think it’s possible that the stars were separated from the galaxy cluster or were thrown out after the galaxies merged. Others think they were present in the early years of galaxy cluster formation, several billion years ago.
Professor James Jee of Yonsei University in Seoul, Korea, in research published in the journal Naturesaid: “These stars were homeless during the early stages of cluster formation. We don’t know exactly what caused them to become homeless. But one way or another, they were created in large numbers at the beginning of the universe.
“If we find the origin of these stars, we will understand the history of the entire galaxy cluster. At the same time, they may act as traces of dark matter surrounding the galaxy cluster.”added Professor Hyungjin Joo of Yonsei University.
Black matter is the invisible scaffolding of the universe, connecting galaxies and galaxy clusters.
Scientists hope that the infrared capabilities and sensitivity of NASA’s James Webb Space Telescope will significantly expand the search for stars deep within galaxy clusters, and thus help uncover many hidden secrets.
