The sun is believed to be 4.6 billion years old, but how long this glorious plasma ball exactly took to form is still unknown. A team of international researchers has found the answer to this question ...

Stars are thought to form within enormous filaments of molecular gas. Regions where one or more of these filaments meet, known as hubs, are where massive stars form. These massive stars, located ...

The discovery of a planet that is far too massive for its sun is calling into question what was previously understood about the formation of planets and their solar systems. The discovery of a planet ...

Our solar system is filled with rocky debris tumbling around the sun, most of which is the same age, but sometimes you find something much older.

When most of us learn about the solar system, it seems like a pretty well-ordered place. Our sun formed first, about five billion years ago, and the planets appeared a little later. As a very general ...

You might assume that there has always been water on Earth — that water was there from the very beginning when our planet formed. But scientists increasingly think that water on Earth may have ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of ...

Data from the Atacama Large Millimeter/submillimeter Array (ALMA) shows that the water around V883 Orionis predates the star itself, and that suggests it could be the same for our solar system. Share ...

When you saw the Hale-Bopp comet, you may have seen material from a distant star passing by. In a new study, a team of astronomers argues that most of the comets that streak through our solar system ...

Since the first discovery of planets beyond the solar system in 1995, more than 6,000 exoplanets have been identified. Many ...
