This week the sky will serve as a runway for a real “moon dance”. Earth’s natural satellite will reach its furthest point from the planet (apogee), circle through the celestial hall, and reach its closest point to the Sun (perihelion) in its current orbit. After this extraordinary solo performance, she still performs two accompanied pieces. […]

In the vast cosmos that surrounds us, the Solar System hosts more than just planets in its orbit. Among the stars that parade across the vastness of space, dwarf planets appear as intriguing puzzles that challenge our conceptions of what constitutes a planet. Let’s explore what a dwarf planet is, how it differs from a […]

As reported by , the Perseid meteor shower peaked this weekend, around 1:30 a.m. (Brasilia time) on Sunday (13).

An over 100-year-old female Greenland shark found stranded on a beach in Cornwall (England) last year died in her teens. This is because the species can live up to 500 years, being considered the longest living vertebrate animal on Earth. While this is indeed an admirable lifespan, it falls far short of the longevity of […]

Four new species of feather stars have been discovered in Antarctica. They look like aliens, they belong to the echinoderm family, the same as starfish, but unlike them, these animals can have up to 20 legs. These new species belong to the group Promaccrine, a genus of free-swimming stemless crinoids. Until then, they were considered […]

One of the great mysteries of US history remains unanswered. The city of Cahokia, located in what is now the US state of Illinois, was home to approximately 15,000 people and was considered one of the most important in the region.

The Solar System is an impressive landscape of celestial bodies, with planets varying in size, composition and, of course, distance from our home, Earth. Looking at the night sky and gazing at the stars is an activity that makes us wonder about the vast cosmic distances and how big our universe is. A doubt that […]

Every year, between mid-July and late August, the Earth passes through the debris cloud left by comet 109P/Swift-Tuttle. When these residues reach our planet’s atmosphere, the Perseids occur, a meteor shower with greatest visibility in the northern hemisphere, but also observable (to a lesser extent) in countries below the equator, such as Brazil – depending […]

Chinese military complaint have significantly advanced the development of laser weapons, thanks to a state-of-the-art cooling system created by the country’s National University of Defense Technology. With it, high-energy equipment can stay powered up indefinitely without overheating, according to the developers. Laser technology has been around for decades, but the excess heat generated by these […]
