He continued: "It is a key question how star formation got going early in cosmic history. "We live in a universe of stars," Volker Bromm, a professor of astronomy at the University of Texas, said in a press release. These stars, born from the hydrogen and helium gasses that clouded the early universe, are likely 10 to 100 times larger than our sun and would be found in the furthest reaches of the observable universe. The astronomers, led by Anna Schauer, a NASA Hubble Fellow, hope to study some of the first stars formed after the Big Bang, more than 13 billion years ago.

One big drawback? Ionic liquid salts aren't highly reflective alone. Ionic salts are also much less dense than mercury and closer to the density of water, giving them a significant weight advantage. As Borra explained to NASA, ionic liquids evaporation rates are nearly zero and can remain liquid at the very low temperatures you would find inside a crater of the moon. One solution may be organic compounds known as ionic liquid salts. It would quickly turn to solid from the moon’s frigid temperatures and would easily evaporate when exposed to lunar vacuum. However, mercury would be unusable on the surface of the moon. Mercury, which is a metallic liquid at room temperature, reflects almost 75 percent of the light it receives, making it almost as effective as silver-coated mirrors. The LZT, like most liquid-mirror telescopes on Earth, uses mercury as its reflective liquid. To top it off, the telescope comes with a tripod, a finder scope, and a backpack to carry it all.

With two eyepieces-10mm to 20mm-it's suitable for a range of stargazing experiences. Great for beginners (and priced accordingly), this option features a wide, 70 millimeter aperture that will make stars and constellations appear bright and clear. But now, more than a decade later, astronomers from the University of Texas at Austin have resurrected the telescope and propose to build a new LLMT, nicknamed the “Ultimately Large Telescope.” The telescope was ahead of its time-so much so that NASA scrapped the idea because there wasn't enough supporting evidence for the existence of the ancient stars the telescope planned to study. The unbelievably large telescope, called the Lunar Liquid Mirror Telescope (LLMT), would have used a large spinning mirror made of liquid and be placed on one of the moon’s poles to study the earliest stars born in the universe. Let's nerd out over the universe together. In 2008, a group of astronomers from around the world came to NASA with a wild idea: Why not put a giant telescope on the moon? This telescope, nicknamed the “Ultimately Large Telescope,” could be different.Scientists already proposed that idea to NASA years ago, to no avail.Astronomers from the University of Texas at Austin want to build a telescope on the moon.
