Scientists in Mexico are examining a mysterious metal orb recovered in Colombia, sparking UFO interest.

The sphere, filmed floating before crashing near Buga in March, has decorative etchings and reportedly no visible welds.

Researcher Jose Luis Velazquez said X-rays show it has three layers of varying densities.

However, physicist Julia Mossbridge dismissed alien origin theories, suggesting it may be an art project, The Hill has reported.

The Pentagon recently reported no confirmed UFOs or alien interactions, despite public speculation.
