According to CNET, the long-delayed James Webb Space Telescope of NASA will be able to stare at the past and illuminate the birth of the first galaxy in the universe. But some astronomers want to go further and study the earliest stars. A radical lunar telescope concept may achieve this goal.

A group of astronomers from the University of Texas at Austin re-examined the concept of building a liquid mirror telescope on the moon. This concept was first put forward ten years ago, but it was shelved by NASA. Researchers will publish a new paper on this idea in a future issue of the Journal of Astrophysics.

This kind of lunar telescope will be unusual. It breaks the use of solid mirrors, as we see in james webb. The researchers said: "The mirror of the telescope will be a rotating liquid bucket with metal on it-so it is reflective-liquid."

The telescope needs to be 330 feet (100 meters) in diameter and can be built in lunar craters at the two poles of the moon. It can run on solar energy. Compared with telescopes made of traditional materials, liquid mirror telescopes are easier to transport to the moon. Its size and location will make its power amazing.

In keeping with some interesting naming conventions of earth telescopes (look at the very large array in the United States and the very large telescope in Chile), the Lunar Observatory will be called the "ultimate telescope".

This is not the only lunar telescope concept that scientists are studying. NASA is funding a study on the idea of using radio telescopes to turn lunar craters into disks. This requires the use of robots to lay barbed wire on the crater.

"The appearance of the first star marks a key change in the history of the universe," Brom said. "When the original conditions set by the Big Bang gave way to the increasingly complex universe, it finally brought life to planets, life and intelligent creatures like us."
