China's Tianwen-2 space probe, which is set to bring back samples from an asteroid for research, has reached its target after traveling 1 billion kilometers (620 million miles) over more than a year, the Chinese space agency said Monday.

With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we have the potential to see (or in some cases, listen) farther and more clearly than ever before. That is certainly the case for the new Square Kilometer Arr

Water flowing from hot springs near volcanoes often contains a mixture of meteoric water that has percolated underground and a deeper component known as magmatic water. Researchers at the University of Tsukuba used numerical simulations and isotopic data to show that magmatic wat

Visitors to the Fernando de Noronha archipelago, located about 340 miles (545 kilometers) off the coast of Pernambuco in northeastern Brazil, soon notice a small lizard. Seemingly ubiquitous, it roams among rocks, trails and urbanized areas, approaching people and stealing food i

New roads bring changes to the regions they traverse. They can enable job opportunities, access to medicine and health care, and electricity. But they also disrupt local ecosystems and can have surprising consequences for human health, including increased disease risk.

A new study published in Quaternary Science Reviews dates the dramatic collapse of one of the largest glaciers ever documented in the Himalayas. The findings overturn a long-held assumption about what sustains wet-climate (monsoon-dominated) glaciers.

Pyrite, an iron sulfide ore, is often known as fool's gold because its shiny metallic luster and pale brass-yellow color can easily fool the untrained eye into mistaking it for real gold. This time, however, 360 kilometers (220 miles) south of Tokyo, scientists have uncovered inv

As scientists around the world closely monitor the possible development of a powerful "Super El Niño," a new study suggests that another tropical ocean deserves equal attention. Researchers have found that temperature changes in the Indian Ocean can significantly influence winter

Ocean tides push upstream along coastal rivers, in some cases reaching hundreds of kilometers (hundreds of miles) inland. These inland stretches are known as tidal rivers, and they're the scene of complex interactions between the river current and tidal oscillations. When rivers

Elephants can communicate with other elephants across distances of up to five kilometers (3 miles) by producing sounds that travel through the air. However, they have a second way of sending signals: seismic waves traveling through the ground. These vibrations are transmitted fro
