Astrophysicists suggest that Venus "swallowed" its own Moon

Público15 September 2026 at 10:03

US astrophysicists have put forward a surprising hypothesis to explain the absence of a moon around Venus. According to this theory, the planet may have "swallowed" its own moon in a phenomenon described as "celestial cannibalism."

The American team proposes that Venus may have captured a moon that ended up colliding with the planet, or that the moon was slowly dragged toward Venus's surface over millions of years due to the gravitational interaction between the two bodies.

The mystery this theory aims to solve relates to the fact that Venus has no moon, despite being a planet very similar to Earth in terms of size and composition. This absence has intrigued scientists for decades.

The "celestial cannibalism" hypothesis thus emerges as a likely explanation for this phenomenon, suggesting that Venus may have once had a moon that ended up being absorbed by the planet itself.

Alert in Castelo Branco: Mosquito that transmits dengue and zika detected in the municipality

The Local Health Unit of Castelo Branco issued an alert confirming the detection of the Aedes albopictus mosquito, known as the tiger mosquito, in the municipality. This invasive species is capable of transmitting serious diseases such as dengue, zika and chikungunya, although authorities stress that no mosquito infected with virus has yet been identified in Portugal. The detection results from the work of the Vector Surveillance Network (REVIVE), which monitors the expansion of this species in national territory since 2017, having already been registered in Covilhã and in the Algarve and Alentejo regions. Authorities have activated an enhanced response plan to monitor the evolution of the insect in the region.
