You live on Earth. The Earth is part of a planet-moon system that is part of a larger solar system. The solar system revolves around a single star in the Milky Way galaxy. The Milky Way galaxy is home to at least 100 billion stars and maybe as many as 400 billion … and it’s just one galaxy. Now, in a new research paper, a team of astronomers has announced the discovery of 44 completely new galaxies, each containing countless stars, planets, moons and you. Wait, not you, but everything else before that.
The researchers used data from various sources to hunt for previously undiscovered galaxies hiding in a space of space called the Fornax cluster. The Fornax cluster is a cluster of galaxies about 65 million light-years from Earth that has been a huge source of galaxy discovery in the past. In this case, data from several surveys and observation campaigns have been used to detect the presence of 44 new galaxies, but they are nothing like the Milky Way.

There are many different types of galaxies in space. Spiral galaxies like ours are only one type, and each variant of the galaxy can be in different sizes. These new galaxies are what are known as UCDs or ultra compact dwarf galaxies. As the name suggests, these galaxies are extremely compact and are only about 200 light-years away. By comparison, the Milky Way is thought to be approximately 100,000 light-years in diameter, lasting or lasting several lifetimes.
Because they are smaller in size, they also contain fewer stars. UCDs are estimated to contain approximately 100 million stars, although this is again a very rough estimate. These “tiny” galaxies are a relatively recent discovery for scientists, with the first UCDs classified less than two decades ago. They are also quite a bit harder to spot than their larger, more impressive counterparts, and that’s why they may have been hiding in data already studied.
After searching for available information, the research team had a huge 220 potential candidates for UCD. That’s a lot, so the scientists decided to focus their efforts on objects that are probably UCDs. They ended up with 44, which are probably new galaxies yet to be documented, and are located near the edge of a larger cluster. The researchers say the new galaxies are more than 1,170 light-years away from the core of the cluster, which may also have made it harder for them to spot in previous research efforts.
“With deep optical images of the Fornax In-Depth Survey, combined with public infrared data, we are revisiting the UNA population of the Fornax cluster and, for the first time, systematically searching for UCD candidates up to the virium of the cluster galaxy,” the researchers explain.
At a distance of about 65 million light-years from Earth, the impressive fact is that we can know that these galaxies exist. Unfortunately, it will be a long time before we have the technology to learn much more about them or what they contain.
