Thanks to new technology, we can better measure distances in space. But we still face some problems:

1. Accuracy Problems: Tools we use can be thrown off by the air around us, which can cause mistakes in measurements.

2. Huge Distances: Space is really big! Even small errors can become big problems when measuring long distances.

Here are some ways we're working to fix these issues:

• We are building better space telescopes to avoid problems caused by the air.
• We are using techniques like parallax and lidar to get more exact distance measurements.

With ongoing effort, we can solve these challenges!
