In May 2024, auroras were observed at unusually low latitudes across the globe, lighting up skies that rarely see such displays. Inside Earth's magnetosphere, the region of space surrounding our planet and dominated by its ...

Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit ...

The Himalayas are often seen as one of Earth's great natural barriers, separating the heavily populated and industrialized regions of South Asia from the remote Tibetan Plateau. But new research, published in Geophysical ...

Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied ...

Over recent decades, harmful algal blooms have become increasingly common. These blooms often consist of bacteria called "cyanobacteria" in freshwater ecosystems. They can produce debilitating toxins, suffocate marine life ...

Astronomers from Germany and Turkey have analyzed available data from various space telescopes to investigate an ultraluminous X-ray source designated X-4, which is located in the nearby galaxy NGC 4631. Results of the new ...
