This cylindrical projection global map is one of six new color maps of Saturn's midsized icy moons, constructed using 10 years of image data from the Cassini spacecraft. Discovered by Cassini (the astronomer) in 1684, Dione is about 1,120 kilometers across. Based on data extending from infrared to ultraviolet, the full resolution of this latest space-age map is 250 meters per pixel.
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.
We all know Usain Bolt is one of the fastest people on Earth. Now, students have shown his superhuman speeds would actually allow him to fly like a bird on one of Saturn's moons while wearing a wingsuit.
The world-record holding sprinter has reached top speeds of 12.27 metres per second, which would be fast enough for him to take off on Titan while wearing a regular wingsuit.
Theoretically, the Olympic athlete would then be able to soar above the planet – without any need for propulsion.
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.
