Mystery of how the Moon formed may be solved: it was born in just five hours after Earth's collision with a planet the size of Mars

SAPO Notícias5 September 2026 at 12:04

The mystery of how the Moon formed may finally be solved. Scientists propose that our natural satellite was born in just five hours after a violent collision between Earth and a planet the size of Mars.

This theory dates back about 4.5 billion years, in a period when early Earth had no oceans, continents, animals, or plants. The Solar System was still in its infancy, and collisions between worlds were a natural part of its evolution.

The particularly violent collision is believed to have given rise to a debris disk that eventually aggregated to form the Moon. This new scientific model may explain the characteristics observed both on Earth and on our natural satellite.

Researchers believe this theory resolves some of the outstanding questions about lunar formation, offering a more precise explanation for the process that created the Moon in just a few hours after the catastrophic impact.

Lito Sousa: ANVISA authorizes import of experimental medication for influencer's treatment

The National Health Surveillance Agency (ANVISA) authorized on Friday (4th) the exceptional import of the experimental medication ALN-6457, developed by Regeneron Pharmaceuticals, for the treatment of influencer Lito Sousa, who lives with Creutzfeldt-Jakob disease, a rare and rapidly progressive neurological condition. The authorization was necessary because the pharmaceutical company does not have a legal representative in Brazil and the drug is not commercially registered with the agency, in addition to being in the pre-clinical study phase, meaning it has not yet been tested in humans with this condition. The request was made by Hospital Israelita Albert Einstein after Lito was accepted for compassionate use of the treatment.

The Mediterranean is seeing its temperatures increase at twice the rate of the global average temperature increase

The Mediterranean is experiencing a temperature increase twice the global average, according to climate change experts. Filipe Lisboa, an expert in the field, analyzes the growth in meteorological instability associated with global warming, with special emphasis on the increase in ocean temperatures, which contributes to more extreme climate conditions in the Mediterranean region.

Why Brazil 'grew' in new map approved by the UN

Brazil appeared larger on a new world map approved by the United Nations (UN), due to an update of the global geodetic system (WGS84). The new cartography reduces distortions that shrank countries near the Equator line, such as Brazil, and enlarged territories near the poles. The correction benefits not only Brazil but also other tropical countries, and should impact areas such as navigation, telecommunications, and defense.

Ocean heat waves have already claimed a land victim: children living in coastal cities

A study led by researchers from Penn State and the University of North Carolina, published in the Proceedings of the National Academy of Sciences, revealed that marine heat waves — periods during which ocean surface temperature remains abnormally high — are affecting the health and survival of children in coastal communities in low- and middle-income countries. Climate change is impacting these communities that depend on the ocean for food and financial livelihood, with children being particularly vulnerable to the effects of ocean warming.
