Learn how you can say farewell to comet 3I/ATLAS as it passes by Earth on Dec. 19, 2025, and what we have learned during its brief visit near Earth.

From an early age, we are taught to understand that the planets of our solar system change in position while orbiting a central star, the sun. But does the sun itself move within the solar system?

The solar system originated from a collapsing cloud of gas and dust approximately 4.5 billion years ago, with the Sun forming in the central region through nuclear fusion and the planets condensing ...

Astrophysicists are mapping a vast, hidden structure in the gas around the Sun that behaves like a tunnel carved through ...

Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

And the earth was without form and void, and darkness was upon the face of the deep. Sometimes, if the night is dark and clear enough, you can look up and see the Milky Way in its arc across the sky.
