The Buga Sphere is a real metallic sphere that crashed in Buga, Colombia, in March 2025. The origins of the sphere are highly speculated, with some claiming that it’s a manmade art project and others claiming that it’s of alien origin. Nothing has been proven, but there have been similar objects found to be manmade.

The Buga Sphere is a mysterious sphere that crashed in Buga, Colombia. The sphere is of unknown origin, but was discovered in March 2025 by local resident Jose Arias. When it was discovered, it reportedly resembled a soccer ball, weighed 4.5 lbs (2 kg) before ballooning up to 22 lbs (9.8 kg), was cold to the touch but instantly turned water into steam, and apparently made Arias sick (although no radiation or chemical residue was found around the site).^{[1]

- What is the Buga Sphere made of? The Buga Sphere is reportedly made of an aluminum alloy, three circular, metal-like, seamless layers, and has mysterious glyphs etched into the surface.
- It also apparently features a honeycomb structure that’s visible under a magnifier and has nine microspheres that surround a central nucleus.
  - These discoveries were supposedly made through X-ray by Jose Luis Velazquez, a radiology specialist.
- Videos of the sphere have reportedly featured it making zig-zag motions in the sky and shifting in altitude before crashing out of the sky, but some have called these out as fake.^{[2]

The origin is unknown, but some speculate that it’s from space. Some speculate that the Buga Sphere is from space due to its unique composition. Mexican ufologist Jamie Maussan, Dr. Steven Green, and other prominent figures in the UFO community argue that the unknown alloy that makes up the sphere, as well as the impeccable construction, are proof that it’s of alien origin.^{[3]

- Some argue that when it comes to scientific matters, Maussan isn’t credible, as he has a history of advocating for extraterrestrial theories later revealed to be hoaxes.^{[4]

In a post on X on May 27, 2026, @FalconSpaceLabs said they visited Mexico and drilled into a second, recently discovered Buga Sphere. In the second sphere, they found screws, epoxy, and other materials that suggested it was manmade. Based on this discovery, people in the replies of the post have concluded that the first sphere is also manmade.

Nothing has been confirmed, but the space relation could be a conspiracy theory. According to conspiracy expert John Paul Gomez, “Most conspiracy theories begin with [a] kind of gap in knowledge. A small piece of information gets misread or taken out of context, someone spins a story around it, and others add their own interpretations.^{[5]

- Since there isn’t much scientific research around the Buga Sphere, any current theories may simply be conspiracies that are trying to fill the knowledge gap mentioned by Gomez.

The Buga Sphere was indeed discovered in Buga, Colombia, but the theories about its origin are simply theories. Nothing has been proven that confirms that it comes from outer space, but it is a real object that is currently in the possession of Jaime Maussan.^{[6]

Theories About the Buga Sphere

One Reddit user believes the Buga Sphere is a hydrazine propellant fuel tank due to the spherical composition of both objects. In a post on r/Aliens, u/The_Necbromancer explained that it looks like a Dremel was taken to it and that they noticed the guidelines used for the glyphs. Although it’s plausible, this theory has not been confirmed.

Others speculate that the Buga Sphere is an alien communication device. Some online users believe that the glyphs on the Buga Sphere are a type of alien language that’s meant to send a message to those who can read it. Reddit user u/lizilok explained that they believe, “The strange engravings on [the sphere’s] surface might be a form of alien communication, similar to how we sent the Voyager Golden Record into space.”
- Others online have claimed that the glyphs translate into specific messages, with one Medium poster claiming that AI models translated them into a message that reads “Beware the sky, signal received.”

One theory claims it’s a missing core for ancient temples and pyramids. This theory says that ancient temples were designed with Earth’s vibrational harmonics in mind. According to the theory, the Buga Sphere was a core for these temples and helped power them when specific Sanskrit sounds were chanted. This theory suggests that the sphere is a technological artifact with specific abilities.^{[7]

- This theory has arisen mainly because the sphere reportedly responded to frequencies in the range of 190-300 Hz.
This theory has been proposed by Dr. Julia Mossbridge, a physicist from the University of San Diego, who noted that things like magnetic pulse welding and superplastic forming may be responsible for producing the seamless look on the Buga Sphere’s exterior.^{[8]
