The Hubble Space Telescope has captured a view of thousands of stars shining in shades of blue, gold and orange, according to Space.com. The image shows a dense ball of stars called Messier 30, or M30, and was released by the European Space Agency on Nov. 5.
Beyond its beauty, the scene matters to astronomers. Space.com reported that some of these stars are almost as old as the universe itself and could help explain how the Milky Way came to be.
M30 is a globular cluster, which Space.com describes as a roughly spherical collection of tens of thousands to millions of stars held together by gravity. It sits about 27,500 light-years from Earth, in the constellation Capricornus.
The Milky Way is home to at least 150 of these ancient stellar gatherings, according to the report.
Some globular clusters in our galaxy are estimated to be between 11.5 billion and 13.5 billion years old. For comparison, the universe is about 13.8 billion years old, which means the oldest of these clusters formed very early in cosmic history.
The old stars in these clusters preserve chemical clues about the conditions that existed when they formed. By reading those clues, astronomers can piece together the early history of the Milky Way. In that sense, a single sharp image of a cluster like M30 is also a window onto a period that no telescope can observe directly.
This is the part of the story that makes M30 more than a pretty picture. Astronomers have found that M30, along with several other globular clusters, travels around the Milky Way in the opposite direction to the galaxy's rotation.
That unusual motion raises the possibility that M30 did not form in our galaxy at all. According to Space.com, it may have been captured by the Milky Way billions of years ago. The idea is a possibility rather than a settled conclusion, and the report does not present it as proven.
For readers, the takeaway is that the glittering dots in this photograph are potentially fossils of two stories at once: how the oldest stars of the universe formed, and how our own galaxy grew, perhaps by absorbing objects that began their lives elsewhere.
Space.com featured the picture as its space photo of the day for Nov. 11, 2026. The image itself was published by ESA on Nov. 5. The report describes the view as a dazzling display and focuses on what the cluster can tell researchers rather than on any new measurement made with the picture.
A globular cluster is a tightly packed family of stars that formed together and has stayed together for billions of years. M30 is one of at least 150 such clusters around the Milky Way, and its backward motion makes it a candidate for a cluster that was captured rather than born in our galaxy. Studying objects like it is one of the ways astronomers work out the early history of the Milky Way.
