Science and Technology

Elon Musk could compromise night sky observation with a $2.4 trillion plan that envisions more than 1 million satellites; simulation indicates up to 14,072 visible objects in São Paulo, and astronomers issue a worrying warning.

Science and Technology

A planet 120 light-years away orbits two “failed suns” in a nearly perpendicular trajectory, challenging planetary formation models and revealing one of the rarest systems ever observed by astronomy.

Science and Technology

Astronomers identify 45 rocky planets that could harbor life, and one of them is just 4.2 light-years from Earth, making it the closest neighbor with the potential to have liquid water on its surface.

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

Libya built over 4,000 kilometers of underground pipelines to bring water from the Sahara to coastal cities in a project that the government itself called the Eighth Wonder of the World.

Almost 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland. Houses form a continuous row, and behind them, narrow agricultural strips emerge, creating one of the most unusual rural patterns in Europe.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

Described by astronauts as one of the most unlikely natural phenomena on Earth, the Okavango Delta spreads over up to 15,000 square kilometers in the middle of the desert and transforms Botswana into a living labyrinth of channels, islands, and flooded areas.

Two helicopters, 41 people, and over 38 tons of bait were mobilized on a remote Pacific atoll to eliminate rats; five years later, native trees grew by 5,000%, seabirds gained habitat, and the rainforest began to regenerate.
