American astronomers say new evidence supports the idea that a large telescope on the moon could study the oldest stars in the universe.

Now, a group of astronomers at the University of Texas at Austin say they have found new evidence that a telescope on the moon would be able to gather data on the first stars in the universe.

The first stars in the universe are believed to have formed more than 13 billion years ago.

The stars are thought to have formed after the Big Bang – the large explosion that many scientists believe created the universe.

The team says these stars were born out of a mix of hydrogen and helium gas.

The scientists say their moon-based observer would be able to gather data on the oldest stars, which no other telescope is equipped to do.

NASA has plans to send the James Webb Space Telescope, its newest telescope, to space in October 2021.

NASA says the telescope is designed to look deeper into space and offer more answers about the past than any other spacecraft.

It is a large infrared telescope, with a nearly seven-meter mirror for exploring space.

He added that the James Webb Space Telescope is expected to reach the time when galaxies first formed.

The team is proposing that the world astronomy community revisit the plan to use a lunar liquid-mirror telescope as a way to directly observe these early stars for the first time.
