Interesting facts

A 454-gram stone that fell to Earth may be the last remnant of a planet between the Moon and Mars that disappeared 4.56 billion years ago, claims Aaron Bell’s team, which says they only know of this world’s existence because fragments of it landed here.

Giant Magellan Telescope promises to find “new Earths”: Observatory with a 25.4-meter mirror and resolution up to 10 times superior to Hubble’s will be able to photograph cold exoplanets and search for signs of life beyond the Solar System.

NASA has just tested a “giant” the size of a car that could change everything in the lunar race: a fuel cell that turns water into energy and then recharges itself, without any refueling from Earth. See how it works.

Something strange happened in the Earth’s core in 2011, scientists analyzed 27 years of data and discovered a reversed flow under the Pacific that still defies explanations about the planet’s magnetic field.

Japan is about to launch a satellite that captures solar energy in space and sends electricity to Earth in the form of microwaves. The technology promises to generate energy 24 hours a day without relying on clouds, night, or solar panels on the ground.

Science and Technology

A new study overturns the central idea we learned about planets and suggests that Earth is the exception rather than the rule; most rocky worlds in the galaxy may not have a core or mantle, just a single turbulent fluid extending to the center.

Science and Technology

Scientists have discovered that the Earth recycles its own continents in the depths, dragging pieces of crust down during plate collisions and returning them later as magma, in a mechanism called relamination that has helped build the continents for billions of years.

Science and Technology

The Earth’s core is younger than the surface for a reason that seems like fiction, but involves Einstein, gravity, and a 2.5-year difference in the planet’s clock.

Science and Technology

Earth is passing through the radioactive debris of an ancient supernova, and scientists have found frozen evidence in Antarctic ice with traces of iron-60 still falling on the planet.

Newly discovered asteroid with potential for urban destruction will pass at just a fraction of the distance to the Moon, leaving scientists alert to a possible warning.

Lunar samples collected by the Chang’e 6 mission reveal changes in the asteroids that hit Earth and the satellite billions of years ago and challenge the hypothesis about the arrival of water on our planet.

Mars may rely on asteroids to come off the drawing board: scientists propose seeking metals in space, using other bodies as fuel stations, and facing journeys so slow that a Martian base would take generations to be built far from the current Earth.

Mother and daughter build a 70 m² house with more than 8,000 discarded glass bottles and impress with their creativity; known as the Casa de Sal, the property is located on Itamaracá Island, in Pernambuco.

Workers were opening a new road connection near the Marginal Tietê when they found, in the underground of the construction site, remnants of locomotives, wagons, and boilers from the 19th century linked to the forgotten history of Lapa.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

He transformed an abandoned plastic water tank into an underground house in the “hobbit hole” style, using only repurposed pallet wood, without heavy machinery or expensive labor.

China has deployed snake-shaped robots to slide along power lines, where they have already inspected over 130 kilometers of cables using cameras and sensors to detect damaged wires, worn-out parts, and overheating.
