Stars and planets are naturally associated with one another. While some planets have gone rogue and are drifting through space, the vast majority are in solar systems, where they’re gravitationally

An international team of astronomers has performed multi-band radio observations of diffuse radio emission in a galaxy cluster known as Abell 3558. As a result, the observational campaign detected that

Trans-Neptunian objects (TNO) are some of our solar system’s lesser-known objects. They number in the thousands, and they get their name from their orbits. These dwarf planets orbit the sun

Interstellar objects are visitors from solar systems beyond our own, and the third ever such object, known as 3I/ATLAS, has just been discovered. Using the Gemini North telescope, astronomers have

View of Earth as seen by ESA project astronaut Sławosz Uznański-Wiśniewski inside the seven-windowed cupola, the International Space Station’s “window to the world.”

Alone among known planets, Earth has vast oceans on its surface and its landmasses are marked with lakes and extensive river drainage systems. Water is the biosphere’s lifeblood, and without

A new method to analyze gravitational-wave data could transform how we study some of the universe’s most extreme events—black holes smashing into each other.

Our circumstances here on the wondrous, life-supporting Earth can give us a false understanding of what the universe is really like. But our blue-skied, temperate planet is the extreme exception

The International Space Station’s first visitors from India, Poland and Hungary headed back to Earth on Monday, wrapping up a private mission and catching a ride home with SpaceX.

An international team of astronomers report the discovery of a long-period radio transient, which is unusually circularly polarized and showcases an accelerating spin period. The finding of the new transient,
