Narrator: Serious scientists, like myself, believe our solar system was formed by the collapse of a giant cloud of gas and rock and is held together by the gravitational pull of the Sun.

This stunning photo shows every single planet in the solar system at the same time during a rare alignment that won’t happen again until 2040. Taken from a field in Somerset, the groundbreaking ...

The Solar System's journey around the Milky Way's center takes it through varying galactic environments. "Imagine it like a ship sailing through varying conditions at sea," explains Efrem Maconi ...

The way people think of the Solar System has changed many times throughout history. Before the development of the telescope, these ideas were based on what could be seen with the naked eye.

This week Mercury joins the queue. Now every other world in our solar system will be visible among the stars at the same time — if you know where to look. According to Gerard van Belle ...

The team's research indicates the solar system's passage through the Orion region occurred between approximately 18.2 and 11.5 million years ago, with the most likely time between 14.8 and 12.4 ...

Now, researchers develop a green solvent system for fabrication of large-area perovskite solar modules using industrially viable and scalable deposition methods, which achieve high power ...

Here's how to spot it and why it happens. The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations ...
