NASA's Chandra telescope shows the Milky Way is bigger than we thought

NASA's Chandra telescope made a new discovery.

The Milky Way's arms may be longer than we knew.

Scientists used two telescopes to measure dust clouds in the Milky Way's arms.

They used special bursts of energy from far away to measure the dust clouds.

This is what the Milky Way might look like with longer arms.

NASA is working on new moon missions.

The new method is more direct and doesn't rely on assumptions about the Milky Way's rotation.

The dust cloud in the farthest arm is about 3,500 light-years wide.

Astronomers have known about the Milky Way's arms for a long time, but mapping them is hard.

Here is a picture of the Milky Way near a park in California.

NASA is giving money for moon missions.

The new method of studying gamma-ray bursts could change how we understand our galaxy.

The new distances are important for understanding the Milky Way and its mass.

The downside is that suitable gamma-ray bursts are very rare and hard to find.

The scientists will keep looking for more gamma-ray bursts.
