Astronomers have discovered a remarkable planetary system where three very different objects orbit a distant star—and their paths are constantly changing. The system, known as...

Scientists have long known that most of the matter in the universe is invisible. This hidden material, called dark matter, makes up about 85%...

Astronomers have captured striking new details of powerful jets shooting out from a black hole, revealing just how much energy these cosmic systems can...

Astronomers have long been puzzled by the discovery of extremely large black holes in the early universe. Some of these black holes, found less than...

In 2014, a strange cloudy object called G2 made a close approach to Sagittarius A*, (Sag A*) the supermassive black hole at the heart...

Space is full of objects that push the boundaries of imagination, but few do it quite as effectively as a black hole. At its simplest,...

Scientists have long suspected that water exists on the moon, but exactly how it got there—and where it is most concentrated—has remained a mystery. Now,...

A new study based on samples from China’s Chang'e-5 and Chang'e-6 missions is helping scientists understand how the basic ingredients of life arrived and...

The nebular hypothesis states that stars and the planets that orbit them form from the same reservoir of material, called a solar nebula. It's the...

For decades, scientists believed the early universe was filled with enormous amounts of hydrogen gas—the basic ingredient needed to form stars. But proving this idea...

Supermassive black holes sit at the centers of most large galaxies, and they are some of the most powerful objects in the universe. Scientists believe...

Jupiter and Saturn are the two largest planets in our solar system, and both are surrounded by dozens—even hundreds—of moons. But their moon systems look...

The most luminous quasar, known as SMSS J114447.77-430859.3 or simply J1144, has been observed in X-ray emissions. This observation provides a fresh understanding of how...

Analysis of radio pulses that passed through a galactic halo reveals a surprisingly quiescent halo with very low density and weak magnetic field. Using one...

Mars was once wet, but now its surface is desiccated. Its meagre atmosphere contains only a tiny trace amount of water vapour. But new research says...

One hundred years ago, on November 23, 1924, a groundbreaking discovery reshaped our understanding of the universe. A small article in The New York Times...

The Parker Solar Probe detected streams of high-energy particles that align with the supergranulation flows within coronal holes, revealing that these regions are the birthplace of the so-called "fast" solar wind.
