Next Tuesday, a lunar eclipse, often referred to as a 'blood moon,' will occur, but it will only be partially observable in Brazil. Residents of São Paulo and much of the country will be able to see a penumbral shadow covering the moon in the early morning hours, although this may be subtle enough to go unnoticed by some. In the western states of Amazonas, Acre, Roraima, Rondônia, and Mato Grosso, there will be a chance to view a partial eclipse early in the morning, providing an opportunity for those in these areas to see more than just the penumbral shading. This partial visibility adds to the excitement of the celestial event, offering a rare moment for sky watchers. A lunar eclipse occurs when the Moon passes through Earth's shadow, resulting in its characteristic reddish hue during the eclipse, often described as a 'blood moon.' According to NASA, this red coloration happens because the Earth blocks most of the sunlight, allowing only the filtered light to reach the Moon's surface through Earth's atmosphere. This event is not just a visually stunning spectacle but also an interesting reminder of the relationship between our planet and its natural satellite.
