The cosmos is vast, peculiar, and brimming with unanticipated phenomena. It drives us to launch interstellar probes to distant parts of our solar system and beyond, motivates us to construct telescopes, and inspires us to send astronauts soaring into the void.
In the inaugural episode of the series Farscape, currently available on Peacock, astronaut John Crichton embarks on an experimental spacecraft that utilizes Earth’s gravity for a slingshot into distant space. His aim is to expand human exploration, and he achieves this goal, although not in the manner he anticipated. During his swift journey around the planet, Crichton becomes entangled in a roving wormhole and is displaced to the farthest reaches of the galaxy.
Currently, astronomers have authenticated the presence of an unpredictable colossus in our reality – a solitary black hole traversing our beloved Milky Way Galactic system.
Hubble confirms first rogue stellar-mass black hole ever discovered
In 2022, a group of astronomers identified a potential roaming black hole, approximately 5,000 light-years away in the constellation Sagittarius. Initial observations indicated an object with an extraordinary amount of mass, but the scientists were not certain about its identity. Some hypothesized it could be a black hole with stellar mass, while others speculated it might be a less massive neutron star.
New data gathered from the Hubble Space Telescope supports the hypothesis that this is indeed a wandering black hole, marking the first time such an object has been found among stars of stellar mass. This groundbreaking finding was reported in the prestigious journal, The Astrophysical Journal.

Previously, every identified black hole was bound to a galaxy, star cluster, or other substantial and observable objects due to their gravitational nature. The process of locating black holes is unique because they don’t emit light and can’t be observed directly with traditional methods. Instead, astronomers find and investigate black holes by detecting the gravitational impact they have on nearby objects or by studying the rapid, heated matter rotating around a black hole’s event horizon. It’s simpler to locate black holes when they are part of a galaxy system.
Astrophysicists believe that untraceable black holes might be wandering through space, thanks to their exceptional ability to evade detection. However, even though they’re skilled at staying hidden, they can’t escape the pull of their immense gravitational force.
How astronomers detected a wandering black hole in our galaxy
In 2011, the initial indication of an unruly black hole emerged when it moved in front of a faint, distant star. Black holes possess such an immense gravitational pull that they noticeably bend space around them. As one passes in front of another object, such as a star or galaxy, this bent space functions like a lens, intensifying the light from behind it. Additionally, astronomers observed that the magnified starlight appeared to change position due to its close encounter with the mysterious object.
Researchers can’t directly observe a black hole, but they can detect its influence on other celestial bodies such as the bending of light (lensing effect) and the gravitational pull on nearby stars. This new study is based on recent observations made with the Hubble Space Telescope in 2021 and 2022, as well as archival data collected between 2011 and 2017. With the newly gathered information, scientists have estimated that this object has a mass approximately seven times greater than our Sun, thus placing it within the realm of stellar-mass black holes.
Given that we’ve discovered one solitary black hole wandering near us within our own galaxy, it’s highly probable that many more exist. Astronomers speculate there could be up to 100 million isolated black holes in our galaxy. Thankfully, the vastness of space makes it unlikely that any of them will approach us in the foreseeable future.
