The companies want to put a 2-meter radio antenna along with a smaller optical telescope on a lunar peak, most likely the 5-km-high rim of a crater called Malapert. From this position, both telescopes could view the center of our Milky Way galaxy with unprecedented clarity because they wouldn't be subjected to our atmosphere's hazy interference. The moon would also block them from radio and other electromagnetic noise created by modern civilization. Astronomers have long proposed putting similar telescopes on the moon's far side – which faces permanently away from our planet – because the pictures could exceed anything produced by the best terrestrial or even space-based instruments.
Yummy Moon by artist Yona Lee uses 450 partially eaten Nilla Wafers to depict the different phases of the Moon. A photo on Lee's site shows the artist using a projector to map the image and match the shape of the cookies to various shapes needed to display the Moon's phases.
Pluto, a distant icy dwarf planet, orbits the Sun 29 times farther out than the Earth and has estimated surface temperatures of -380 degrees Fahrenheit (-229 degrees Celsius). These frigid temperatures are far too cold to allow liquid water on Pluto's surface. Its location and small size make it very difficult to observe; however, with NASA's New Horizons mission slated to reach the distant world next year, scientists hope to map Pluto and its moons in great detail.
Current models predict one moon in particular, Charon, is of great interest to study. The models indicate Charon has surface fractures, indicative of a possible subsurface ocean. Further analysis is needed to determine in the moon's interior is warm enough to support liquid water.
